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. As with all Capp pipettes, the Comfort features Capp's innovative control knob (please see video for demonstration), this feature allows the same pipette handle to be converted from a variable volume pipette to a fixed volume pipette simply by changing the control knob. This control knob also makes the Capp pipette one of the easiest and most intuitive pipettes on the market to calibrate. The SoftLine adds a comfortable rubber coating on the pipette and it is fully autoclavable. SoftLine series has been discontinued, so take advantage of these great blow-out prices!
