Monitored Pipetting Process
Automated pipetting with ZEUS follows these steps
1. Tip pick-up:
ZEUS automatically picks up a pipetting tip and verifies its presence.
2. Movement to sample:
The tip is moved by the pipetting system over the sample. Then the integrated Z-motion of ZEUS is used to find the liquid level and to follow the liquid during aspiration and dispense.
3. Liquid Level Detetection (LLD):
ZEUS allows two modes for Liquid Level Detection (LLD): by capacitance for conductive liquids and by pressure for non-conductive liquids.
ZEUS automatically aspirates the quantity of liquid defined by the user in the range of 1 μL - 1000 μL into the pipetting tip. Self-monitoring functions of QPM (Qualitative Pipetting Monitoring) ensure precision of the pipetting and prevent malfunction.
The liquid is dispensed in one or more aliquots while monitoring the process with QPM.
6. Tip disposal:
ZEUS disposes the used pipetting tip.
