SPT Labtech mosquito: nanolitre liquid handling - How It Works 

Non-contact, positive displacement dispensing from a disposable tip. Brought to you by the makers of mosquito®.
Positive displacement pipetting is defined by the fact that the piston, moving the liquid in and out of the tip for aspiration and dispensing, comes into direct contact with the liquid itself.
This piston based pipetting action results in highly accurate liquid handling across a very broad volume and viscosity range.
