Air-Z Legacy Pipette Pump - TriContinent

Air-Z Legacy

TriContinent Z-Series OEM syringe pumps (pipette pumps) are electronic air displacement pipette pumps designed for use on liquid handling (XYZ) robotic systems. The compact and lightweight robotic pipette pump simplifies system design by eliminating tubing and priming requirements normally associated with routine liquid handling tasks. Sample transfers or reagent aliquoting can be done accurately and precisely using the TriContinent disposable tips, eliminating cross contamination and carryover.

  • Three available configurations; Z-Series pump, Z-Series with Proximity Sensor and the iZ-Pump.
  • The stepper motor driven syringe will accurately and precisely handle fluid volumes from a few microliters to 5 milliliters.  Precision and accuracy exceeds that of any similarly sized handheld pipette (micropipette).
  • The simple mechanical interface makes it easy to integrate with all liquid handling (XYZ) robotic systems.
  • Developers can use their own drivers for the Z-Series Pipette Pump or they can be matched with the M-Series motion controllers to provide a complete package.
  • Custom volumes and mounting configurations are also available on an OEM basis.
  • TriContinent's Z-Series syringe pumps are also available in an Instrument Ready (iZ-pump) configuration (details can be found on the accessory tab on the TriTon (XYZ) Robot Page).
