Pipetting is a vital component of many laboratory workflows, especially in biological labs that handle cell cultures. Achieving absolute precision in these processes is critical, and serological pipets—designed to transfer liquid volumes ranging from 1 to 50 mL—are often the tool of choice. These sterile, volumetric transfer pipets support aseptic techniques required for cell culturing procedures, keeping workflows free from contamination.
Serological pipets also play a key role in many other lab processes, such as microbial studies, titrations, sample dilution, reagent preparation and more.
Graduations on the sides of serological pipets are commonly used to gauge how much liquid is being aspirated or dispensed. However, achieving precise aliquots can be challenging, as it demands constant attention to the graduation marks. This not only slows down workflows, but also increases the potential for errors and user fatigue during repetitive tasks.
Accurate and speedy pipetting
Pairing serological pipets with a pipet controller—such as the PIPETBOY GENIUS serological pipet controller from INTEGRA Biosciences —can speed up pipetting and increase workflow productivity. The PIPETBOY GENIUS offers sensitive, one-handed control of aspiration and dispense speeds, allowing users to adjust pipet performance on the fly, from precise drop-by-drop delivery to rapid dispensing at up to 12 mL/s. It also incorporates a sterile module (nose piece) with a Steady-Grip feature, ensuring that any volume of serological pipet from 1 to 100 mL is held firmly for enhanced stability and reliability.
The PIPETBOY GENIUS enables researchers to easily switch between manual and repeat dispense functions when used with INTEGRA serological pipets. Users can choose the repeat dispense mode for fast, highly reproducible and hassle-free aliquoting, eliminating manual errors by avoiding the need to look at graduation marks. Pipetting in repeat dispense mode is faster and more accurate than relying on graduation marks, enabling users to precisely aspirate the total desired volume and consistently dispense aliquots from 0.1 to 50 mL—all at the press of a button. As a result, researchers no longer need to pipette at eye level, allowing them to avoid uncomfortable postures and reduce the risk of painful repetitive strain injuries.
The PIPETBOY GENIUS also addresses a common challenge in pipetting: the risk of overfilling, which can cause filter contamination and lead to time-consuming maintenance. The pipet controller features built-in overfill protection when used in combination with INTEGRA serological pipets. This helps to prevent liquid from being aspirated into the instrument, optimizing workflow efficiency and keeping maintenance demands low.
