Computer-controlled linear actuator moves the piston.
Piston moves correct distance, at correct speed, independent of user variation.
The computer operates the actuator when the trigger is pressed. No strain to the thumb and no heavy blowout spring. Pipetting with an EDP2 reduces the risk of repetitive motion injuries. Rapid, no-slip volume setting Setting the volume is fast and easy, using up and down arrow keys, with the volume selection shown on the liquid crystal display. The volume control is locked duting the pipetting cycle, preventing accidental changes.
