Pipette Pumps for All Pipetting Tasks

Since reliability and precision are the foundation of diagnostic and life science instruments, TriContinent pipette pumps are the first choice for leading manufacturers. We offer automated, fully-featured, and programmable air displacement pipette pumps for all liquid handling applications

Our pipette pumps are designed to provide a seamless integration experience. They can be equipped with integrated tip ejection, an automatic liquid level detector, various tips, tip blockage, motor step loss feedback, and more. Our air displacement pipetting modules are available with or without control electronics and a pressure sensor for pressure-monitored pipetting, detecting tip blockage, and more.

TriContinent pipette pumps are manufactured to comply with ISO 13485 certification guidelines. They follow industry-standard protocols to offer plug-and-play 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.

We are a well-established supplier thanks to our industry experience and our offer of exceptional customization options. Our wide variety of pipetting module configurations offers 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 maintenance-free longevity.

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 to aspirate the medium into a disposable tip. The liquid is then dispensed into another container. This technology helps to avoid cross-contamination of the samples and eliminate 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 that of the best hand-held pipettes. This is because hand-held pipettes most commonly utilize plastic “syringe” barrels and plastic pistons. Those are subject to typical molding tolerance variation and compliance in actuation. Yet accuracy & precision (A&P) can still be quite good, especially if “human factors” (e.g. hand shake, hand warming, surface-level immersion variation, speed, etc.) are minimized.

Aspiration and dispense volume accuracy is a function of bore and stroke accuracy. The bore accuracy of TriContinent’s pipette pumps is unmatched. The same accuracy and precision are provided by the borosilicate glass barrels used in TriContinent’s high-precision syringes. There, ID tolerances are consistently held to +/- 5 microns 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.

The TriContinent Air-Z line of automation pipette pumps ensures exceptional performance and longevity. They are arguably the most compact ADP pumps available, which enables the design of smaller benchtop and POC (point of care) devices.

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