No scraping or pipetting is needed to facilitate cell detachment.

Examples of manual pipetting systems are shown for each case.

The pipetting head include an array of tip fittings, e.g. 96.

The preferred pipetting head includes an array of 96-tip fittings.

Methods of operation of the pipetting system are also disclosed.

Pipetting of a staining solution – colour reaction

The example apparatus also includes a pipetting mechanism offset from the second axis of rotation.

Thus, carry-over caused by the pipetting nozzle can be reduced.

enhanced automation including an integrated pipetting system,

A pipette tip magazine for use in an automated pipetting system.

In one embodiment, rinse stations (60, 70) that employ a pipetting syringe to deliver cleaning solvents to cleanse the interior of a contaminated pipetting needle (20) are described.

Four pipetting heads with pipetting volumes up to 12.5 µl, 125 µl, 300 µl or 1250 µl are available for the VIAFLO 96.

This is achieved with the provision on a computer of a simulation of the pipetting robot with control inputs simulated, and responding identically to the pipetting robot on receipt of identical control signals.

If the cells remain attached, repeat pipetting thoroughly to detach them.
