Pipette Pumps for All Pipetting Tasks

Reliability and precision are a foundation of diagnostic and life science instruments. That’s why TriContinent pipette pumps are the first choice for leading manufacturers. We offer automated, fully featured, and programmable air displacement pipetting pumps for all liquid handling applications.

Our air displacement pumps (ADP) are designed to provide a seamless integration experience. TriContinent air displacement pumps come equipped with integrated tip ejection, automatic liquid level detection, and a full range of tip volumes. Our air displacement pipettes are highly modular and can be customized for your specific application.

TriContinent air displacement pipettes can come with or without control electronics. These features allow for the ultimate flexibility for our customers.

TriContinent pipetting pumps are manufactured to comply with ISO 13485 certification guidelines and follow industry- standard protocols to offer complete compatibility. Thanks to their lightweight and compact size, they allow you to save space and simplify the design of your OEM instrument. Sample transfers or reagent aliquoting can be done accurately and precisely, eliminating cross-contamination and carryover.

Our wide variety of pipetting module configurations offer superb flexibility for numerous volumes and mounting configurations. Proven designs leveraging our precision glass syringes and long-life seal technology, provide exceptional performance and enduring zero maintenance longevity.

The Technology behind Air Displacement Pipettes

Air displacement pipettes use the same operating principles as hand-held electronic pipettes or manual pipettes.

The system picks up a pipette tip and then moves to a desired liquid reservoir. The pipette tip is immersed in a vessel containing a liquid. The liquid is then drawn into the pipette tip. The automated pipette is then moved to another container and the liquid is dispensed.

This technology helps to avoid cross-contamination of the samples and eliminates the risk of carryover.

Technical Advantage Overview

TriContinent Air Displacement Pipette’s performance for automated pipette applications is as good as or better than the best handheld pipettes. Handheld pipettes typically utilize plastic pistons, which are subject to a much higher degree of tolerance variation and compliance in actuation.

TriContinent’s air displacement pipette pumps are constructed of high quality materials such as borosilicate glass, stainless steel, and inert polymers. 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 inner diameter of TriContinent’s pipette pump barrel is held to an extremely low tolerance. This low tolerance allows for the incredible accuracy of TriContinent pipettes. Syringe inner diameter tolerances are commonly held to +/- 5 microns consistently along the entire length of the barrel.

Stroke accuracy is provided by the greatest quality and highest resolution motors and linear actuators available in the market today.

The TriContinent Air-Z line of air displacement pipette pumps are some of the most compact available. This small footprint enables the design of smaller benchtop and point of care devices.

OEM’s will benefit, when using a precision gantry robotic system, from TriContinent Air-Z pipette’s speed and reproducibility.
