The Technology behind Air Displacement Pipettes

Air displacement pipettes use the same operating principles as hand-held electronic pipettes or manual pipettes. They immerse the tip in a vessel containing a liquid to aspirate it into a disposable tip and dispense the liquid into another container. This technology helps to avoid cross-contamination of the samples and eliminates the risk of carryover.

Technical Advantage Overview

TriContinent Air Displacement Pipette (ADP) pumps’ pipetting performance for automation applications is as good as or better than the best handheld pipettes. This is because handheld pipettes most commonly utilize plastic “syringe” barrels and plastic pistons, each of which are subject to a much higher degree of tolerance variation and compliance in actuation. 

The vast majority of TriContinent’s automated air displacement pipette pumps are constructed of highly engineered materials such as glass syringe barrels, stainless steel plungers and machined polymer seals based on dynamic seal construction. These materials are manufactured with much lower tolerances compared to parts manufactured with injection molded plastic.

Aspiration and dispense volume accuracy is a function of bore and stroke accuracy. The bore accuracy of TriContinent’s pipette pumps is unmatched because it is the same accuracy and precision provided by the borosilicate glass barrels used in TriContinent’s high precision syringes where ID tolerances are commonly held to +/- 5 microns consistently along the entire length of the barrel. 
Stroke accuracy is provided by the most highly rated, extremely repeatable and highest resolution motors and linear actuators available in the market today.

Besides resulting in designs that provide exceptional performance and longevity, the TriContinent Air-Z line of automation air displacement pipette pumps are the most compact ADPs available enabling the design of smaller benchtop and POC (point of care) devices. 

When combined with the additional speed and reproducibility of an OEM’s precision gantry robotic system carrying a TriContinent Air-Z product, instruments will benefit from unparalleled pipetting performance.
