What Types Of Pipettes Are There?

Pipettes are a common laboratory tool used to transport measured volumes of liquid and come in a multitude of channels, displacements and construction materials. There are different pipettes for all kinds of uses within the lab. Whether a lab is in the market for a new pipette or they are looking for a quality recertified/refurbished Here are the different types of Pipettes that could fit in your lab:

Single Channel Pipettes

Single Channel Pipettes. Pipette.com provides researchers with the widest selection of single channel variable volume and fixed pipettes, or micropipettes, ranging from Eppendorf®, Sartorius Biohit®, Gilson®, Rainin®, Labnet®, AccuPet®, Capp®, and others. Single channel variable volume and fixed volume pipettes are available in both manual and electronic formats. The manual format is the classical design and is the most cost effective. The electronic micropipette format is costlier but has added benefits of increased ergonomics and reduced user to user differences, and increased accuracy and precision.  Most modern models are designed to both meet accuracy and precision needs while being ergonomic.  A focus on ergonomics has come about as more and more scientists have developed Repetitive Strain Injury (RSI) due to continual pipetting.  New features such as light weight models, low plunger forces, and hand hooks have stifled much of the RSI occurring in the lab today.

Electronic Pipettes

Electronic Pipettes. Accuracy, precision, ergonomics and efficiency are of the utmost importance when it comes to choosing your pipettes. One of the most significant advances in pipetting technology was the advent of the electronic pipette, which has revolutionized liquid handling in the modern lab. The electronic pipette is used routinely in all types of laboratories from academic settings all the way to pharmaceutical laboratories and state of the art research labs. Pipettes come in a range of shapes and sizes, and with a variety of different technologies incorporated into their design, enabling scientists to find the best fit for them.

Multichannel Pipettes

Multichannel Pipettes are the easiest way to increase your output and productivity, while reducing assay, testing and production costs at the same time. By purchasing a multichannel pipette for your laboratory: You can instantly increase pipetting productivity by 8-, 12-, or even 64-fold (depending on whether you prefer an 8-channel,12-channel, or higher channel pipette). This immediately creates more time in the day for a scientist or lab technician. Instead of spending hours transferring samples to plates, you can reduce the task to minutes. Multichannel pipettes can increase the throughput of your lab and free-up valuable lab time to be spent on tasks other than time-consuming and repetitive pipetting.

Fixed Volume Pipettes

Fixed Volume Pipette, Micropipette Fixed Volume Pipettes, Micropipettes. Fixed Volume Pipettes are perfect for beginners. Fixed volume pipettes are ideal pipetting units to be used when working with dense or viscous liquids. Unlike adjustable volume pipettes, fixed volume pipettes dispense the same quantity of liquid every time you dispense. The volume of a fixed volume micropipette cannot be changed, which allows the user to work at a faster pace without having to constantly change the volume setting on the side or top of the pipette. With fixed volume micropipettes you are much less likely to suffer an error similar to those errors caused by accidentally changing the volume setting, which can occur with an adjustable volume pipette. Calibration is also much more simple and faster to carry out, as there are far fewer internal components in a fixed volume micropipette than there are in an adjustable volume pipette.

Pipette Controllers

Important things to consider when purchasing a motorized pipette controller include speed, ergonomic design, accuracy, convenience and cost of the controller. The importance of each of these factors to you will depend on your needs and applications. Considering each of these points will ensure that you pick the right product for your lab. Motorized pipette controllers are an essential these days in any lab that uses serological pipettes. While the old 3-valve pipette fillers and pipette bulbs are great in their simplicity, newer motorized pipette controller technology provides a myriad of benefits for your laboratory that were not previously available. If you are looking to upgrade your serological pipetting, an ergonomic controller will save you time in the lab and reduce fatigue for the user. Controllers are a great way to pipette large volumes of solutions in an efficient manner. Pipette.com offers affordable prices for your pipette controller needs.

Serological Pipettes

Commonly utilized in the laboratory for transferring a few milliliters of liquid to up to 100 mL in volume via a serological pipettor.  Serological pipettes can be used for mixing chemical solutions, mixing cell suspension, transferring liquids, and accurate measurements of liquid.  Conveniently, all serological pipettors will fit into any serological pipettor and allow for fast volumetric measurements. Serological pipettes allow even distribution of cells throughout a solution, a key step in the cell culture process.  They can also be used to gently mix suspensions, reagents, or even creating gradients in reagent layering. Pipette.com offers a plethora of serological pipette options that will suit any laboratory need you might have from basic volumetric measuring to cell suspension and reagent mixing.

Positive Placement Pipettes

What are positive displacement pipettes? Positive displacement pipettes work like a syringe. The samples come into direct contact with the tip and piston, increasing precision and accuracy and eliminating the air cushion. The direct contact with samples results in the aspiration force remaining constant. Positive displacement pipettes are recommended for: Viscous and dense liquids Samples are aspirated and dispensed more slowly than water in a traditional air cushion pipette, which can lead to inaccurate volumes and residue attached to the tip wall.  Syringe/ Piston tips wipe the tip walls clean. Liquid examples: Tween™ 20, sulfuric acid, concentrated DNA / RNA, glycerol Volatile liquids Evaporation can lead to inaccuracy and the pipette dripping in traditional air-cushion pipettes, positive displacement pipettes prevent vapors from moving into air space. Liquid examples: acetone, ethanol, methanol Radioactive, infectious, and corrosive liquids Positive displacement pipettes prevent aerosolization of solutions into an open-air space. Liquid examples:concentrated sulfuric acid, concentrated hydrochloric acid, biological samples, Iodine-125 Detergent containing/ foaming liquids Sealing of piston with the tip wall reduces foaming and bubble formation. Liquid examples: serum, SDS, Mucasol™

BottleTop Dispensers

The bottle top dispenser you choose depends on your needs. Important factors to consider include the volumes you will be dispensing and the type of liquids you will be dispensing. Typical liquids you may need to dispense include strong acids and bases, saline solutions, organic solvents, trace metal free liquids, sterile media, etc. Another factor to consider is whether you want a manual or digital unit. Below you will find options available from both categories to meet your specific needs. Other bottle top dispenser options that vary between different models and brands include the method of liquid dispensing, price and added features such as analog or digital display, etc

Transfer Pipettes

Disposable Transfer Pipettes are the Safer Alternative to Pasteur Pipettes. These one-piece, unbreakable low-density polyethylene plastic transfer pipettes are inert to biological fluids and most acids. They are a great alternative to Pasteur pipettes as you no longer have to deal with the hazards of broken glass and finding the correct bulb for your experiment. Since they are disposable, you longer have to worry about cross contamination between samples. They are well-suited for blood banking (2 mL size), urinalysis, hematology, wet chemistry, microbiology, and serology. The low-affinity surface reduces the loss of cells and valuable proteins due to binding. Can be sealed and refrigerated.

Pasteur Pipettes

Pasteur Pipettes, also known as droppers or eye droppers, are laboratory liquid handling tools that are used to transfer small quantities of liquids. Pasteur Pipettes are traditionally made from glass, although nowadays plastic Pasteur Pipettes are commonplace in labs around the world. Pasteur Pipettes are essentially glass or plastic tubes that are tapered to a narrow opening point at the lower end and fitted with a plastic or rubber bulb at the upper end. The combination of a glass Pasteur Pipette and rubber bulb can also be known as a ‘teat pipette’.
