Weighing only 130g it ensures comfortable ergonomic and problem-free pipetting. Each time the 'pump' button is pressed approximately 2ml of sample fluid is drawn up. When the 'out' button is pressed the liquid is gently released via an accurate valve system with the amount of pressure exerted on the Blow-out button determining the speed of release. Blow-out pipettes can be fully emptied by pressing another button on the back of the unit. A standard PTFE membrane filter prevents overfilling.
