How It Works: Electronic Multichannel Micropipettor

Multichannel micropipettors have drastically increased the rate at which samples can be prepared for modern high throughput assays. By automating the process with a fine-tuned digital motors and on-board software to conduct various pipetting tasks (forward, reverse, and repetitive pipetting, stepping, mixing, sequential aspiration, and programmable combinations of steps) electronic multichannel pipettors, such as the Finnpipette Novus from Thermo Fisher Scientific, shown here, take pipetting to a new lux level.

Ergonomics is a dominant design principle, and it's become apparent to manufacturers that this means making devices customizable for multiple users. Many multichannel models feature rotating tip cone modules 1 and this model, has a moveable trigger 2 to help righties and lefties find a comfortable hand position.

Tip ejection becomes more difficult with increasing channels. Ejection for a 12 channel module can require as much as 100 Newton. That's a lot...
