There is a wide variety of pipettes available for clinical, forensic, drug discovery, chemistry, or any other life science research and analysis protocol you have. For experiments that need reliable and accurate liquid handling during sample preparation, you need to select the right pipettes for your lab if you want reproducible results.
Having the right equipment can make or break any experiment that requires liquid handling. Whether working with manual pipettes or an automated pipetting solution, accurate and repeatable results are the main goal for any researcher—and this often depends on the instruments you use.
In this guide, you'll learn about the latest pipettes available and how to select the right one for your experiment.
Choosing the right pipette for your lab will depend on the application involved. You'll need to consider the type of liquid, the sampling volumes, task complexity, and the throughput required for your experiments.
There are a few major parameters to consider before you can narrow down your options to the right instrument. These are:
Air-displacement pipettes work well with aqueous liquids, but when you're handling problematic liquids, you'll need a positive-displacement model. Some of the biggest sources of pipetting errors are simply due to not selecting the right pipette for the liquid handling application involved.
There are also some collective considerations for choosing the right pipettes for your lab. If you'll be doing manual pipetting, you should select an instrument with a lightweight, ergonomic design to give you the ability to pipette longer without fatigue. Additionally, you'll need to know if the device features a volume-locking mechanism, or is autoclavable. Depending on your applications, you can also choose pipettes with a fixed volume.
Below, we discuss some of the best pipette types to select for your lab.
A fixed volume pipette is adjusted and factory calibrated at a specific volume, and dispenses the same quantity of liquid every time you pipette. Our PIPETMAN® L Fixed air-displacement pipette comes in fifteen different models that cover a range of volumes between 1 μL and 5 mL. With a lightweight design and a fixed volume that eliminates the risk of any volume error, these are the ideal pipettes for clinical diagnostics, quality control, and routine testing applications even for lesser trained lab technicians. These pipettes allow the lab techs to work faster and more confidently without having to adjust or verify the volume setting of the pipette.
Other benefits of fixed volume pipettes are:
Positive-displacement technology, like that used in our MICROMAN® E pipettes, is ideal when working with infectious, viscous, foaming, hot, cold, or volatile liquids.
The disposable piston within the capillary piston (CP) tip is in direct contact with the sample. The CP technology thus removes any air cushion inside the pipette and ensures the volume accuracy is not affected by the fluid's properties. This also helps prevent contamination and protects the sample, the user, and the pipette.
A MICROMAN E pipette gives you:
Figure 1. Comparison of the air-displacement and positive-displacement pipettes. Panel A shows the working principle of air-displacement pipettes with the piston integrated into the lower part of the pipette and an air cushion between the sample and the piston. Panel B describes positive-displacement pipettes: the disposable piston is part of the capillary tip and there is no air cushion that could be affected by the properties of the sample.
A single or multichannel PIPETMAN® L features reduced pipetting and tip ejection forces, a lightweight and improved ergonomics for a better balance and more comfortable use of the pipette. The design helps you pipette for longer without suffering from fatigue that could introduce errors into the sampling process. With improved comfort, PIPETMAN L offers accuracy and repeatability levels greater than the ISO 8655 requirements and meets the demand of users who need comfortable, secure, and reliable pipetting activities.
PIPETMAN L variable volume pipettes are:
For repetitive manual pipetting tasks, a Bluetooth® -connected pipette may help bring greater traceability to the lab. The PIPETMAN® M Connected pipette interacts in real-time with the TRACKMAN® Connected pipetting system, making planning and executing pipetting protocols faster, easier, and more reliable. It also offers accuracy and precision in both standard and repetitive pipetting modes, which helps to reduce errors in the lab.
Other benefits include:
In situations where you need to fill 96- to 384-well microplates accurately and repeatedly, the PLATEMASTER® is easy to use and provides high-throughput to match your lab's needs. You can reduce error while increasing your throughput without compromising on accuracy. With the PLATEMASTER, you're able to fill 96-well microplates in as little as 20 seconds and a 384-well plate in less than a minute.
The PLATEMASTER allows you to:
For maximum throughput, while maintaining accuracy and repeatability, a PIPETMAX® automated pipetting solution provides an efficient platform for many liquid handling protocols. Researchers at the University of Missouri can prepare samples for 2,000 RT-qPCR reactions every week using a PIPETMAX liquid handler.
A PIPETMAX bench-top liquid handling solution can:
At Gilson, we provide access to the instruments and consumables that you need to produce trusted results. Our liquid handling solutions ensure that you can achieve your desired level of throughput without compromising on your experiments' precision, accuracy, or repeatability.
