6 reasons why you might want or need a centrifuge


Centrifuges use high rotational speeds to separate different materials according to their densities. These devices are common in laboratories, dairy applications, and they are also becoming popular among cooking enthusiasts who prefer a scientific approach to preparing delicious meals.

There are quite a few reasons why you might want to get a centrifuge, from lab work to doing your own experiments to separating different ingredients when cooking.

What is a centrifuge and how does it work?

A centrifuge is a machine that usually has a rotor which uses centripetal acceleration to separate liquids or suspended solids from liquids. These devices have angled drilled holes that are used to place sample tubes. The centrifuge can separate materials and even macromolecules according to their density and sedimentation rate.

By spinning, materials will tend to go towards the outer wall of the tube and settle on the bottom. While initially invented to separate milk and cream in the 19th century, nowadays centrifuges can be found in laboratories all over the world, as well as in many food processing plants.


Use a laboratory centrifuge for experiments

With a quality centrifuge, you can perform a variety of experiments and procedures, from isolating DNA for analysis to separating various cell organelles from cellular extracts and preparing them for study or further tests.

There are lots of models to choose from so you can be sure that you get the proper tool for the job. With a microcentrifuge, you can use tubes between 0.2 and 2 ml and separate various proteins or other macromolecules.

You could also calculate the hematocrit or the percentage of red blood cells in the blood, as well as obtain a complete blood count which can serve various purposes, besides the obvious medical investigative ones.


Get a high-tech device for sophisticated work

For finer analytical work, you can also get an ultracentrifuge. This high-tech device is capable of spinning at higher speeds while also offering many more features for complex laboratory work. These units offer the possibility to monitor samples in real time and observe the separation process and concentration of sediments. You can use an ultracentrifuge to separate even small molecules with sizes of 100 Da to larger ones of up to 10 GDa.

Preparative ultracentrifuges can also be used with gradient solutions in order to obtain different layers containing isolated particles such as lipoproteins or cellular organelles. These devices can be successfully used for a wide range of applications in biochemistry, biology and molecular studies, or polymer science.

While chances are you won’t be able to afford such a device for your home, you can surely do some research on some of the best models on the market and arrange for one to be bought for the university lab.


Improve your cooking

More and more chefs are turning to centrifuges to help them separate or filter different components in various foods. These devices can save a lot of time, as well as enable cooks to obtain different extracts that would have been difficult to obtain otherwise.

Some use centrifuges to separate tomato pulp from liquid and oil. The aromatic oil on top can be used for other purposes or finer dishes. You can easily obtain other aromatic oils from herbs, nuts, and other ingredients that you can use to flavor a huge variety of foods.

You can use this unit to produce a delicious juice from fruits and vegetables in a short amount of time. You can even obtain clear juices from ingredients such as carrots or peas, as you could easily separate the pulp from the liquid and enjoy a fresh cup of juice in no time.

Centrifuges are also appreciated for their predictability, which helps in obtaining quality extracts in a consistent manner. Another advantage is that they don’t take forever as natural settling techniques do, and most procedures usually last no longer than a few minutes.


Make purees and butterfat at home the faster way

Besides experimenting with food and doing crazy things such as creating semi-transparent tomatoes, you can also use a small centrifuge to make purees and butterfat at home. In a short amount of time, you get the pulp of fruits and vegetables settled on the bottom of the recipients and all you need to do is to add spices and a bit of oil, and you’re done.

With a good centrifuge, you can also separate milk from cream and fat and make homemade butterfat of various concentrations to use it for desserts or other dishes.

Benefit from a multipurpose design

While in the old days, a centrifuge had a compact body, a metal rotor, and some basic speed settings, you can now find models that can perform complex operations which can help you shorten centrifuging cycles, or save time through automation.

New models come with high-performance microprocessors which control a wide range of functions. You can benefit from remote operation, or use the internal memory to program spin cycles at various intervals and different settings.

One of the best things about the memory feature is that you won’t have to waste time writing down all your protocol procedures, as the device will be capable of recording and keeping a log of all your work so that you can always access it or transfer it to a computer using a USB cable.


Enjoy an easy operation and sleek design

Despite their ever-growing sophistication, centrifuges are becoming easier to use. They have intuitive interfaces so you can control every function through a few sensitive buttons. Thanks to the automatic locking and unlocking mechanisms, you won’t have to fear a critical failure that could destroy the rotor, damage the centrifuge, or even cause harm to someone.

You can also select between many modes, countdown ranges, spin speeds in rpm, interval durations, etc.

Modern centrifuges aren’t just technologically advanced and easy to use, but also good-looking, with many featuring elegant designs with large LCD displays that can show several parameters clearly. Most models are also quite silent when operating so you won’t be bothered as you go to perform other laboratory tasks while the centrifuge does its job.

best microcentrifuge 1700

Whether you’re looking for the best refrigerated microcentrifuge or a benchtop microcentrifuge, you’re in the right place. We have taken the time to perform an extensive research on the topic so that we create a comprehensive guide that can hopefully assist you when it comes to making the right call. If you’re still trying to find the answer to the question “How does a microcentrifuge work?”, all you have to do is keep on reading.


Tube type

Microcentrifuge specifications are different from the ones you’d find in product descriptions belonging to standard versions. Full-size alternatives can spin tubes of which the volume ranges from 1.5 to 2 milliliters although there are several adapters that can be utilized in order to modify this type of tube capacity. Typically, microcentrifuges are capable of spinning small tubes with a capacity ranging from 0.2 to 0.5 milliliters. As is the case with standard products, these kinds of centrifuges also require certain adapters if you want to use larger or smaller test tubes.

Many lab grade microcentrifuges have their limitations, in that they can be used strictly for certain purposes. While a myriad of models have interchangeable rotors that allow them to be rather versatile when compared to their counterparts, there are still units out there that should be employed strictly for particular tubes such as cryotubes, PCR strips, or microtiter plates. Therefore, this is by far the first thing to look for when deciding on one microcentrifuge over the next mainly because the prospective buyer should consider his or her purpose and correlate it to the tube type and capacity.



Aside from the sample volume, you will also have to look at the capacity of the product. Just how many of these tubes can you use at a time? Is the unit compatible with different adapters or even with another rotor? They say bigger is better, and we are not here to disagree because in this case, getting a larger rotor with 48 places for tubes, for instance, will allow you to use the same rotor for 24 samples.



The speed of a microcentrifuge, expressed as the RPM, is also rather important depending on the nature of the samples you will be using. Rotors have their limitations in that they are programmed to avoid going over a certain speed so that they don’t become damaged. A 48-place rotor might be rated differently when compared to a 24 one. As for the actual RPM, the limits should be as broad as possible. If you have the budget to choose a unit of which the minimum rotational speed is 100 and the maximum one is 15,000 RPM, it’s probably the best choice to spend your money on.

In order to avoid any sort of compatibility issues, it might be recommended that you choose a rotor from one of the benchtop centrifuge manufacturers you plan to buy your unit from.

As for the type of rotor, you have to select a fixed-angle rotor or a swing one. These two are different from one another and cannot be used to mimic the features of their counterparts. That’s why it may be a good idea to assess your requirements before choosing one rotor over another.


Rotation speed

As is the case with any other model that you might be tempted to buy at some point or the other, the rotational speed is a critical factor also when choosing a benchtop clinical centrifuge. Expressed as the number of revolutions per minute (RPM), you’ll find this info in most product descriptions. If you don’t come across this detail, we recommend you to get on the phone with customer support as the velocity is most important when trying to obtain various types of organic sediments. The higher the speed, the less time it will take you to get the right sample. It’s important to note that some centrifuges come with fixed speeds, so you won’t be able to use them every time.


Ease of use and energy efficiency

While figuring out how easy it is for you to utilize a centrifuge can be done just by going through several user reviews, estimating the energy efficiency of a model is a daunting task. High-end models usually have high power requirements so they’ll take a toll on electricity bills. If this is not one of your concern as you are not the one paying the bills for the laboratory, perhaps this detail might be of less importance.

Hettich 320RPLATE 


3.Hettich 320RPLATEThe Hettich 320RPLATE is yet another model to consider if you’re looking for a sturdy centrifuge that does exactly what it has been designed to do. The neat thing about this unit is that it comes with temperature control, which means that users can select any of the temperatures they prefer in the range of -20 to 40 degrees Celsius. As is the case with other models in the line, the Hettich 320RPLATE comes with a swing-out rotor.

Based on the information that we were able to gather about the Hettich 320RPLATE, it looks as if it does not come with an adjustable rotational speed. Instead, all of the samples have to be done at 4000 revolutions per minute.

Depending on the nature of the samples that you might need to use, this might be an advantage or a disadvantage. For instance, the Hettich 320RPLATE does prove its worth when working with blood, urine, and cell/tissue plates. Also, the same model manages to offer great results if you’re looking to utilize it in areas such as cytology.

In spite of the fact that it costs less when compared to the previously showcased Eppendorf unit, this one comes with a complimentary rotor, buckets, adapters, as well as biocontainment lids.

Top Rated Centrifuges – Ratings & Comparison in 2018


These days, centrifuges have a lot of uses in many fields of science, and not only. The market is overflowing with models, which is why it can be rather difficult for you to find exactly what you might be looking for. This site will assist you with finding the right centrifuge for your needs and preferences as we’ve consulted a plethora of resources before putting together all of these articles that can hopefully allow you to make an informed choice.

Some of the most well-known uses for such devices include laboratory separations, isotope separations, material synthesis, commercial applications, aeronautics, and astronautics, as well as geotechnical centrifuge modeling. Even though few people are aware of this fact, any washing machine relies on the same operating principle as the centrifuge you might find in a lab. What’s more, the oil industry has been built around the use of centrifuges given that when it is being produced and squeezed from olives or seeds of any kind, oil doesn’t come out looking clear at all. The sediment can be separated with the help of a simple spinning process, but since the oil quantities that need to be packaged and shipped later on are fairly high, the models used in such factories nowadays are very large and have industrial capabilities. Therefore, it is easy to see why centrifuges are currently being employed in various domains and why they will probably never become obsolete.

Best benchtop centrifuge 1700

Most people who may want to invest their money in a centrifuge at some point or the other are most likely not looking for industrial models. You may intend to buy a unit that can be used in your high school laboratory so that you can show to your students how the sediment can be created from milk, oil, blood or any other type of substances. Perhaps you work in an analysis lab where you need to tell people how they stand from a health viewpoint. Whatever the case, you’ll find all there’s to know about these products on our website.



How to choose the best centrifuge


An online market is a crowded place nowadays, with many products being worth their weight in gold. To select the right kind of centrifuge, you should look at the application you’re purchasing the model for and whether you plan to use it rather often or not. Additionally, consider convenience and ease of use. If you want to learn the basics of buying the perfect centrifuge, just read the next buying guide.



Just what are you trying to achieve by utilizing a centrifuge? While many units come in various shapes and sizes, the detail that separates them is their intended purpose. There are now four types of uses that you might be interested in getting a centrifuge for. The ones that are built for industrial applications are, in most cases, screen centrifuges which usually come equipped with many screens. A clothes washer is a type of industrial centrifuge, for instance.

The aerospace industry also relies on using such devices, but the ones that are employed in this field are considerably larger than any of the others we’ll describe in the buying guide. With the help of such models, the resistance of various pieces of equipment or materials can be tested as if the items were to float through space, which means that owning and using a centrifuge can be critical to the success of NASA operations.

Such devices are also utilized in the nuclear industry, but these models are specially designed so that they separate the isotopes of gas. Whether the ambition of the users, in this case, is to enrich weapons or energy production, the fact of the matter is that centrifuges have also proven to be quite useful in this domain, as well.

The most common applications for a centrifuge are medical and lab use, although the two tend to intertwine. Two types are rather popular in the medical field, and they consist of hematocrit units and ultracentrifuges. The first can be utilized to count the number of red cells given that the blood sample will be separated into a plasma layer and a red cell layer. This allows the physician or specialist to count the hemocytes so that a diagnosis is set with regard to whether the patient is suffering from iron and B12 deficiencies, bone marrow disorders, dehydration, and other health issues. Ultracentrifuges are mostly utilized in molecular biology and biochemistry, where they prove to be extremely useful for DNA extraction, for instance.

Best Eppendorf centrifuge 1700

Rotational speed and rotor design

These are two core features to take into account when deciding between one model and another. The rotational speed, expressed as RPM (revolutions per minute), is even more important than the rotor design, as the RPM defines the capabilities of your chosen product. While some come with a fixed RPM such as 1,000, other units allow a certain degree of adjustability on the part of the operator, in that he or she can select revolutions ranging from 800 to 1,000 and more, depending on the sample they’re using. Keep in mind that, at a higher rotation, the sample will be done in less amount of time. However, the nature and material of the sample should also be considered as some can’t resist to too high RPMs.

The rotor design matters especially if you want to avoid compatibility issues. If you were to own a centrifuge and try to buy a rotor replacement, you’d need to look at many details to see whether the two are a perfect match. Regardless of the capacity and style of the rotor, you’ll have to decide between a swing one and a fixed angle rotor. It’s worth pointing out that one cannot be converted into the other, so you need to know beforehand exactly what kinds of samples you’ll be using.


Reliability, ease of use, and operating costs

As the heading suggests, aside from the actual characteristics of the model you may want to invest your money in, you’ll also need to consider factors that are rather hard to grasp from looking at a product description. When it comes to ease of use and reliability, you’ll have to refer to some of the best centrifuge reviews to see what other owners just like you have to say about the capabilities of the product. The operating costs are relatively hard to tell, but there is a pointer you can pay attention to. The higher the power necessities of a product, the less energy-efficient it is. If you’re buying the centrifuge for a lab where you’re not the one paying the bills, this might be less of a problem. If, however, you want to perform some tests at your personal office or home, this might be a crucial detail.

Types of centrifuges


Since centrifuges come with different features and can be destined for unique purposes, we’ve thought about making it a whole lot easier for prospective buyers to select the right one. Following months of research, we’ve come up with a short categorization of the most common types of centrifuges you will be likely to stumble upon while completing your buying journey. We have chosen to review three main kinds mostly because they are among the most critically acclaimed alternatives and manage to be great choices for various science fields. Keep reading if you want to learn all there’s to know about microcentrifuges, benchtop versions, and Eppendorf models.



Best microcentrifuge


Microcentrifuges are popular in laboratories as their use is close to mandatory when it comes to achieving the right consistency of some samples. As their name suggests, these models are mostly designed so that they work best with vials of which the volume is up to five milliliters. Of course, there are some exceptions to this rule, such as various Eppendorf models whose capacities may range between 15 to 50 milliliters, given that these models can accommodate larger conical tubes. However, in most cases, a microcentrifuge comes with a rotor that cannot be used for vials larger than five milliliters.

When trying to decide between one model or the next, you ought to consider the speed and capacity, as you would when selecting a regular centrifuge. The rotor can differ greatly with regard to the number of samples you will be using at the same time. If you want your microcentrifuge to perform its task with up to forty-eight standard tubes per session, it goes without saying that you should look at the configuration of the rotor and see whether or not it can accommodate this many plastic or glass vials. Some units come with complimentary adaptors which can be used to decrease the volume of the tubes you’ll be using. Instead of the tubes flying around during the revolving process, you’ll be able to place them neatly in the rotor without worrying about them ever being misplaced and as such, affected in any way.



Scilogex 91101511 D2012


1.Scilogex 91101511 D2012 Personal MicroThis Scilogex model is one of the most user-friendly ones we’ve come across which is why we felt compelled to recommend it for many kinds of purposes. Whether you’re looking for the best centrifuge for cell culture or plan to stick to a hematocrit alternative, this microcentrifuge can raise up to par as it features an adjustable rotational speed which may be customized between 200 RPM and 15,000 RPM.

In spite of the fact that the rotor featured by the Scilogex comes with 12 places intended for 2-milliliter test tubes, the manufacturing brand has tailored the product to the needs of users who also may need to use .5 and .2ml vials.

None of these sample tubes are provided in the pack, which is a detail that’s worth mentioning considering that you ought to own them already or buy them separately.

Since personal microcentrifuges aren’t created to accommodate larger tubes, you won’t be able to use 5-milliliter ones or any larger vials at all. All in all, the Scilogex appears to be a more than decent option considering that it is easy to install and utilize and does not raise any technical difficulties even for first-time users.

Best benchtop centrifuges


Compared to their micro counterparts, benchtop options are considerably larger and heavier, which is why they need to be set up in a designated place, where they cannot affect other devices in a laboratory due to the vibration they might create during the rotational process. Many models aren’t capable of RPMs higher than 4000, which is why some of the standard applications for such a product include separating blood from plasma, spinning urine, as well as cell washing.

Typically, benchtop centrifuges can be used with tubes of which the volume is higher when compared to the vials that can be utilized in microcentrifuges. Therefore, these two kinds cannot be compared with one another given that the applications for each of them are unique. The test tubes that can be employed with a benchtop alternative usually come with a capacity ranging from ten milliliters to fifteen milliliters. As is the case with many other models, this type is equipped with a rotor that might come along with the base unit or one that needs to be bought separately. Adaptors must be used in order to tailor the attributes of the tubes so that they are able to go in the rotor adequately.



Premiere XC-2415


4.Premiere XC-2415The Premiere unit is one of the most reasonably priced centrifuges we’ve come across during our entire research, and that must count for something considering that this type of lab equipment doesn’t really come cheap.

As is the case with many other products in the same line, the Premiere XC-2415 has a rotational speed which can be customized between 1,000 RPM and 4,000 depending on the task that you might need to perform at some point or the other. The fixed-angle rotor that this model has been equipped with can accommodate up to twelve test tubes of which the capacity can range between 10 to 15 milliliters.

What is a centrifuge and how does it work


Centrifugation is used in many fields all over the world but the simplest prototype you might be using on a weekly basis is your washing machine. Any clothes washer basically relies on the same operating principle as the machines that are used in scientific laboratories, aerospace labs, as well as some areas of engineering.

The many uses of centrifuges nowadays include anything from separating blood and plasma to doing virtually the same thing for PCR and DNA extraction techniques. Industrial applications also exist where these machines are used rather regularly, although the looks of an industrial centrifuge are considerably different compared to the ones you may own and use on a daily basis for performing blood tests in your lab. These units are larger and bulkier and above all, they have to be in complete accordance with the safety standards imposed by international organisms, as otherwise, they might leak out potentially dangerous gasses or chemical compounds.

A typical lab centrifuge is composed of the following parts: a motor, a spindle and flexible collar, as well as rotor components for inserting the test tubes. The machine has to be loaded and then secured by closing the lid, to prevent the tubes from being damaged as well as the substances therein. These days, digital displays and controls have become more popular than the rotary dial that could be found in older models. On the one hand, using digital controls is more accurate as there will not be any human errors, which might happen if you were not to turn the rotary dial correctly. On the other hand, these settings can be adjusted far more easily so you’ll waste less time customizing the functions of the machine than you would if you were to use a rotary dial-equipped option.
