http://www.quasarinstruments.com/p-16... The Capp Comfort Pipette is one of the most ergonomic pipettes on the market. The discomfort from pipetting does not usually come from the shape of the pipette but from the strain exerted on your thumb. During the pipetting process the most strain comes from ejecting the tip. Capp's innovative Comfort pipette fixes this problem by installing an ejection handle instead instead of an ejection button. The handle requires 70% less force and the force is exerted on your fingers instead of your thumb.
