This site will assist you in discovering the right pipettes for what you have in mind, whether you might be looking for the best multichannel pipette or one of the best electronic pipettes on the market today.
One of the first prototypes of what is utilized in laboratories all over the world nowadays was made of glass, although these days constructing such an item using this material is considered counterproductive. Of course, chemistry professors might argue that the best lab pipettes are built out of glass, as one can look at the graduation as well as the color of the substance while it is gliding onto the container. Nonetheless, we have to face the fact and realize that glass is less durable and even less convenient when compared to different types of plastics, as it doesn’t last as long as the latter.
Transfer pipettes are the most popular form you’ll come across when trying to decide on one model or the next. They are used in the cosmetics industry and a wide array of other fields where their services are required. It should be noted that this is the one of the most affordable kind of liquid handling systems you might stumble upon given that a pack of 100 pieces may cost less than five dollars.
How to choose the best liquid handling equipment
Regardless of the type you desire or require, you’ll find all there’s to know about liquid handling products if you keep on reading.
If you’re looking for convenient and efficient liquid handling products, all you have to do is keep on reading. We know that, due to the wide array of products that are available out there, it might be more or less difficult to get the perfect one. That is why we have created a comprehensive guide that can take you through all the factors you need to consider in order to choose the right unit for your needs. The categories will be discussed in more detail following the guide.
Ease of use
There are two primary types of pipettes or pipettors you’ll come across while doing your research. Most of them are manual, meaning that the user has a significant impact on the operation of the product. However, we’ve recently noticed that electronic alternatives are also becoming popular, due to the fact that they leave no room for human errors. Electronic pipettors are handy if you work in domains where measuring microliters is close to impossible, particularly when performed by a human operator. Traditional models can still be utilized in areas such as microscopy and chemistry, as long as the accuracy of the liquid quantities doesn’t need to be excellent.
In the end, when choosing one model over the next, it is important to analyze your requirements. Just how much capacity would you need from a pipette? Think of the common liquid volumes you utilize on a daily basis and with as many analysis as possible. If you can determine a general amount of substance you might normally employ, there’s nothing stopping you from selecting the perfect product.
Cleaning and maintenance
Plastic pipettes are widespread nowadays as they are extremely affordable. Nonetheless, it might be worth pointing out that the broad variety of these plastic options are disposable, and so you won’t benefit from the advantage of being able to use them time and time again. Sure, plastic doesn’t break as easily as glass. Even so, the walls of most of the best laboratory pipettes that are constructed out of glass are rather thick and somewhat impact resistant.
All in all, you need to be aware of the fact that very few items can be autoclaved unless they are made of glass. These days, there are several types of plastics that have decent thermal resistance, such as the ones employed in the construction of the best ergonomic pipettes, most of which are autoclavable. If you cannot sterilize the product one way or the other, you cannot use it again because plastic items tend to retain part of the substance and therefore, have a high contamination risk.
Material and measuring volume
We’ve already seen how the best lab pipettes can be made either out of glass or plastic, but the goal you are trying to achieve with the help of such a piece of equipment has to be taken into account, as well. Glass items do wonders when they’re used in microscopy, for example, but they might be less recommended for high precision liquid handling, or for qualitative analysis.
What’s more, you might have to look at whether you’re interested in performing qualitative examinations rather frequently. If that’s the case, you may have to choose a graduated pipette. All of these dilemmas can be avoided if you select an electronic option. Unfortunately, electronic pipettors and pipettes tend to cost a lot more than their manual counterparts, so it really boils down to whether you are ready to make an investment. It goes without saying that electronic models can also be used when measuring microliters, which cannot be said for dropping pipettes, for example.
If you have considered all of these factors and still can’t seem to make up your mind about which unit works best for you, we have a valuable tip. You ought to take some time and go through some customer reviews, as lab professionals will undoubtedly express their opinions about a pipettor that costs more than fifty dollars. Moreover, if they have gone through a negative experience, they will document it using the rating system available at most online retailers, including Amazon.
Types of lab pipettes
To make things even easier for you, we have compiled some of the information we have come across during our research. As such, we’ve created a straightforward selection of the critically acclaimed items in their respective category, which you can find below. Once again, we feel the need to point out that your preferences and requirements sometimes matter even more than the features of the device or manual pipette you will be choosing. It is worth emphasizing that all of the following product suggestions have gathered some of the most remarkable user reviews available online, which is why they’ve ended up in our selection.
Pipettes are used rather commonly in different lab areas such as medicine, chemistry, and biology, either as a means of transportation for various liquids or as dispensers. The simplest design you might come across or know thanks to your science classes in school is an item made of plastic that features an area where the operator can press and displace a certain air quantity, therefore allowing the product to absorb a substance. The principle at the base of this phenomenon is the creation of a vacuum.
Most transfer pipettes made of plastic are affordable, as they can usually be purchased in packs of twenty-five, fifty, or one hundred pieces. The number of items in a pack depends on the volume capacity of the products. In spite of the fact that they’re plastic, even these pipettes are graduated, thus letting the user know how much liquid he or she has discharged in a Petri dish, for instance. What’s the difference from one product to the next? The short answer would be that some are sterile whereas others are not. In most cases, if the pipette has a limited capacity, it’s likely to be disposable as it cannot be autoclaved.
DMtse Transfer Pipettes
This pack is one of the most reasonably priced options we’ve stumbled upon, and that definitely says something since it contains one hundred pipettes.
The items are made of plastic and can be used for displacing up to three milliliters of the liquid of your choice. It should be noted that the DMtse transfer pipettes are graduated, and so you can always rest assured that you’ll know just how much liquid you’ve transferred.
The owner feedback with regard to the services offered by this product is impressive as it has received more than one thousand favorable Amazon reviews.

Pipettors typically rely on piston-driven air displacement, thus making it significantly easier for the operator to discharge a certain amount of liquid. These models are also graduated, but the main difference between the classic transfer pipette and a pipettor consists of the fact that the second is constructed depending on four standard sizes. The pipettor often functions thanks to a mechanism that allows it to discharge the same quantity of liquid each and every time. This feature makes this kind of product one of the most advantageous ones ever to have been invented.
Pipettors have to be calibrated from time to time in order to be in complete accordance with their operational principles and to avoid getting false results in lab tests. Most of the manufacturing companies we’ve come across actually recommend users to calibrate their devices every six months so that the accuracy is maintained. The food industry is the only area where the calibration of these devices has to be performed even more frequently than every six months. Quarterly, pipettors utilized in the food or drug industry have to be assessed the accuracy of and calibrated properly.
Scilogex is one of the most well-known brands in the industry of manufacturing lab equipment, so it goes without saying that this product is in complete accordance with the company’s quality standards.
The pipettor has a variable volume that can be customized from 0.1 to 2.5 microliters, depending on the task you may need to complete.
The item is available in different sizes, in case your analysis are even more detailed than this. The most important advantage offered by the Scilogex model is that it is autoclavable, and so it can be used time and time again.

Best multichannel pipettor
If you were to select a multichannel pipettor instead of a single-channel one, you’d have to consider things such as the actual number of channels available as well as the total volume the product can hold. For example, there are units that can hold anything from thirty to three hundred microliters, but they can remove just one or five microliters per channel. In that case, it is easy to see that the use of these devices is beneficial for someone who works with multiple samples at the same time. There would be pointless and counterproductive to use a single-channel alternative, as that would mean the operator should manually have to insert a particular liquid volume into every compartment. In other words, utilizing a multichannel pipettor can increase the productivity and time efficiency of the entire working process.
The only minor drawback that we have got from prospecting the market is related to the fact that multichannel models typically cost around two hundred dollars. This makes them significantly pricier when compared to single-channel versions. Even so, since the vast majority of these products are autoclavable, it goes without saying that you’ll be able to utilize them time and time again.
The 71311212 model is one of the most cutting-edge ones ever to have been designed in this line as it can be used with variable volumes and can make it possible that every micro-size drop is precisely measured.
Another reason you may feel tempted to choose this product is that it is lightweight and compact enough to offer the maximum comfort for the person using it, given that the thumb position it requires is natural.
Thanks to its ergonomic design and reliability, the Scilogex 71311212 is undoubtedly worth considering if you haven’t made up your mind on a different product just yet.

Best dropping pipettes
Dropping pipettes are extremely common in school classrooms and even the homes of people interested in the cosmetics industry, who might perhaps be tempted to manufacture their home-made soaps, facial creams, and other self-care products in the category. There are several differences between the models we have come across. For example, some units are made of glass and come with a rubber teat that lets the operator drop certain liquid volumes into laboratory glass and plasticware. By contrast, some disposable units are entirely created out of various kinds of plastic and come with a bulb built in the main body.
Regardless of whether you prefer using one or the other, you ought to be aware of the fact that glass pipettes can be used time and time again, while plastic options might be less recommended if you’re focused on durability. In most cases, plastic models cannot even be sterilized due to their low thermal resistance. Besides, it would be counterproductive for manufacturers to increase the thickness of the wall of a dropping pipette as it would become less elastic. Therefore, glass units are virtually the only correct choice, in this case, as they are reasonably well-made and can be used multiple times.
Benz Microscope 97-4302
This Benz Microscope pipette pack comes with one hundred and forty-four pieces that all measure four inches.
The neat thing about choosing this set is that all of the pipettes are made of glass and come with rubber bulbs, which basically means that they are durable and can be utilized more than once.
While the glass tube measures four inches, the overall length of every pipette is about five inches. While these pieces are not sterile, they probably don’t even need to be as they are likely to be used in chemistry and microscopy laboratories where they can be sterilized or washed conveniently.

Best measuring pipettes
The difference between dropping pipettes and measuring ones is that the second are always graduated. In fact, the whole purpose of using a measuring pipette is to know the approximate liquid volume you’ve let go of in a glass or plastic container of your choice. There are several types of measuring pipettes. The traditional model that you’d find in ancient chemistry labs relies on the abilities of the operator, who is supposed to hold his or her finger on top of the pipette in order to release or maintain the liquid. Unfortunately, this method is anything but accurate as it is practically impossible for a person to measure an exact amount of substance using just air and a finger.
On the other hand, there are models that come with a rubber bulb or teat, just like dropping pipettes do. These units are supposed to be significantly more accurate when compared to the manual ones we’ve discussed above. However, there are human and mechanical errors that might occur when using these products, just as well. If you are really focused on accuracy, what you need is a pipettor, not a pipette. Even so, measuring pipettes may prove their worth under certain circumstances.
The Lucksender XD-59 is a set consisting of two glass droppers that come with rubber bulbs. The volume of these measuring pipettes is 10 milliliters, so they’re on the larger side when compared to many of their competitors.
With a higher capacity comes more length, which is why any of the two products that can be found in this kit measures 33 centimeters and has a diameter of 1 centimeter.
The measurements performed with the help of the Lucksender XD-59 are reasonably correct, and the core advantage for which you ought to consider this option is that the pipettes are made of glass and need to be washed with a chromic acid solution and can then be reused.

Best electronic pipettors
If efficiency is what you want to get from using a dropper, perhaps you’re in need of an electronic pipettor. On the one hand, the device is precise and leaves no room for error, as long as its calibration is performed regularly. On the other hand, most of these units come with a small LCD screen where the operator can visualize various types of data, which may vary from the dropping volume to the one of the liquid that still exists in the pipettor. The range of the vast majority of electronic pipettors can be customized, in that one can select the proper amount of liquid that needs to be dispersed in the container.
Nonetheless, the capacity of such a pipettor isn’t infinite, so you need to know beforehand about which amount of liquid you’re likely to need to use in the future. If you select a low-capacity model, you may need to refill it time and time again. Bigger is better, in this case, as you’ll have to spend less time on fiddling with parts of the device and you’ll be able to focus on your samples a whole lot better.
The performance and usability of the MPA-1200 cannot be equaled by the ones offered by any of its competitors, and that’s due to several reasons.
For one, it’s cost-efficient and gets the job done exactly how it is supposed to. Moreover, it features a unique multiple dispensing mode that can assist users in saving some time and increasing their productivity and efficiency.
Finally, the model can self-calibrate, and that’s an advantage that has undoubtedly adds up to something. Top it all off with the fact that the capacity range of the product can be adjusted from 100 to 1200 microliters and you’ve got yourself one of the most well-designed single-channel electronic pipettors.
