Cavro®
Air Displacement Pipettor (ADP)

A compact pipetting solution for molecular and cell biology applications

 

Related products:  Cavro Omni Flex  |  Cavro Omni Robot  |  Cavro Disposable tips

A compact, pneumatic pipetting solution
for OEM instrumentation

The Cavro ADP is one of the smallest and most sophisticated air pipettors on the market, combining advanced pipetting, process security and tip eject functionalities in a single unit.

Designed for easy integration into compact instruments,  this pipetting module is ideal for applications that use disposable tips to prevent carry-over or contamination, such as molecular diagnostics, cell culturing and point of care (POC) diagnostics.

It offers high performance liquid handling with improved process security – including pressure-based liquid level detection, tip presence confirmation and pressure data streaming – simplified workflows and lower integration requirements.

The ADP is easily integrated into compact instruments using an optional z-axis or one of your own design, with a slim profile to allow 18 mm tip-to-tip spacing for microplate-based applications in diagnostics, genomics and immunochemistry.

Highlights

  • Outstanding pipetting performance
  • Highly programmable feature set
  • Integrated process security

Fully programmable pneumatic pipetting

The Cavro ADP is a fully programmable pipetting module that uses air rather than liquid displacement to aspirate and dispense fluids. Air displacement pipetting simplifies your instrument design and reduces costs by eliminating system liquids and associated components such as pumps, degassers, tubing, fittings, valves, etc.

This Cavro ADP’s slender design makes it ideal for POC applications, and it is compatible with Tecan’s high quality disposable tips to reduce carry-over and provide precise dispensing.

Excellent pipetting performance

Pipetting performance is comparable to advanced manual pipettors, using a range of disposable tip sizes. The Cavro ADP is factory calibrated to ensure accurate air displacement and minimize pump-to-pump variability.

The pipettor’s validated design will help to simplify your development projects, while its excellent reliability will ensure uninterrupted operation of your instrument.

Maintenance-free design

The maintenance-free design of the Cavro ADP simplifies system integration and reduces maintenance costs compared to alternative pipetting technologies.

The air-displacement pipetting mechanism includes onboard liquid level detection and diagnostics to monitor correct operation. The Cavro ADP can be integrated with any z-axis to fit your system architecture

 

Software

The ADP is supported with Cavro integration kit or Cavro Fusion Software for rapid and easy setup and evaluation with other Cavro components.

Liquid level detection

The Cavro ADP features built-in pressure-based liquid level detection (pLLD) with user configurable settings. Data from the pressure sensor can also be streamed in real-time to enable other pressure monitoring tasks via a host computer, such as blockage or bubble detection.

In addition, the Cavro ADP is compatible with external capacitive liquid level detection (cLLD) technologies (cLLD sensor board available separately), ensuring maximum flexibility for your instrument design.

Tip sensor

The pipettor features an integrated disposable tip sensor to support sample integrity and process security requirements.

Its firmware can determine if a disposable tip has not been picked up or has fallen off the probe, flagging and logging any errors.

Tip ejector

A disposable tip ejection mechanism is incorporated into the design of the Cavro ADP, allowing tips to be ejected by a single command.

The ejector uses the same drive mechanism as the plunger, minimizing weight and further simplifying integration.
