Top Rated Centrifuges – Ratings & Comparison in 2021
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.
Our Top Choice
The great thing about this centrifuge is the large capacity that accommodates up to 20 samples of 1.5-2 ml which is a great plus if you work in a big lab.

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.
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.
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.
6. Scilogex 91101511 D2012 Personal Micro-Centrifuge with Timer

Buy from Amazon.com for ($860.63)
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.
7. Premiere XC-2415 Bench-Top Centrifuge
The 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.

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.
