PipettesPipettes are indispensable equipment in clinical and research laboratories. The design of simple device which is used to transport a measured volume of liquid has come a long way. Consistent calibration allows for better results and saves money on reagents. In addition to precision and accuracy, modern pipette design also focuses on reducing ergonomic risks.


There are different types of pipettes such as adjustable or fixed volume, electronic single-channel, electronic multi-channel, and more.

With a motorised piston, electronic pipettes are more consistent and less dependent on pipetting technique. These systems have ergonomic and throughput advantages that can reduce pipetting fatigue and save time in liquid transfer steps. The tip is placed towards the end or suction area of the tool which helps in accurate and easy injection of fluids. An audible click indicates that the tips are firmly placed and ready for use.

In fully electronic devices, liquid distribution is done electronically and not with finger pressure. Electronic multichannel pipettes are ideal for demanding lab applications, such as delivering a series of different volumes in any desired order or for mixing after delivery. New technologies are available with features such as an easy-to-read menu, many diluting options, and in-lab calibration. High performance micropipettes are automatic devices usually used for volumes between 1 micro liter and 1 milliliter. The MLA Micro D-Tipper 9µL Pipette by VistaLab Technologies features a slim, tapered design and comes with a detipping mechanism located to allow easy access to narrow diameter tubes.

Choosing Pipettes

Make sure that the device you choose is ergonomic, easy to use, accurate and precise. Consider the volume range required, pipette length and tip design. While micropipettes measure a much smaller volume, starting at 1 microliter, other devices generally start at 1 milliliter.

After you have chosen the appropriate pipette for your application, choose the correct tip, ensuring that the design, quality and fit are right for your device. A contaminated pipette or contaminated tips can cause contamination of samples as well. Tips come in different designs such as low-retention, extended length and gel loading tips. Tip ejection forces should also be checked. Sterile standard tips are available for applications demanding the highest level of cleanliness.

It is absolutely vital that pipette you choose ensure accurate and precise results. Pipetting technique, maintenance, and calibration can also influence the quality of the data generated. When it comes to precision, good lab practices such as correct pipetting angle, speed and a smooth consistent pipetting rhythm are also important.
