This describes a technique that involves measuring the volume of fluids aspirated using this LabBot pipetting technology which involves using simple disposable 1ml Luer lock syringes and servo-driven 3 way stop cock valves with silicone tubing.

So although the technique has more functionality than say using a multichannel pipetter (unlimited aspiration and dispensing volume, can be used with different types of pipette tips and different types of liquid handling techniques like (piezoelectric, displacement, pneumatic and peristaltic), the issue is just how does it work compared to a multichannel pipetter or even how it works with a Cavro pump using Upchurch (PTFE) tubing.

This study demonstrates a method using a RaspberryPi based camera that is used for imaging and quantifying the volume of aspirated fluid (having a green dye in this example).
