With over 40 years of experience in automated liquid handling, the Tomtec Quadra4 is the best in class, rugged, cost effective liquid handling workstation for science work-flows.
Whether you are doing in-vitro research, developing new molecular entities, conducting solid-phase extraction, or serial-dilution, the Quadra4 will accelerate your process and time to discovery for the most challenging of projects.
Reliability
The Quadra design has the complex pipettor head rigidly bolted to the frame. This assures the reliability of the Quadra4 by moving the microplate to the pipettor head.
If the pipettor head has to move to the plate, it must withstand that substantial force, increasing risk
Bioanalytical Applications
- 450uL tips with a cannula to access deep well plates.
- Aqueous, to organic, to aqueous, without a tip change.
- Manual or automated vacuum box.
- Stacker in-feed/out-feed for microplates and reservoirs provides walk away automation.
- Six station shuttle to support multiple microplates and reservoirs.
- SPE Liquid/Liquid extraction, optional positive pressure SPE.
- Ultrasonic tip washing.
General Capabilities
