The vacuum is fully adjustable, with a pressure gauge that displays the vacuum level, allowing full control of aspirating speed.

The collection bottle of the V0020 incorporates a reliable Overflow Protection Valve that closes off the tube to the vacuum in the event of a full bottle. In addition, the replaceable in-line filter protects the vacuum pump from contaminants and any moisture that comes through the bottle. Graduations on the collection bottle indicate the amount of fluid collected and when its ready to be emptied. The Handheld Vacuum Pipette has an ergonomic design thats comfortable in the hand during prolonged use. Pressing the button applies the vacuum. The pipette accepts Pasteur pipettes, serological pipettes, and also comes with 2 accessory pipette cones. One cone is designed to accommodate 200/300ul pipette tips, the other has a thin, stainless steel capillary for fine control aspirating.
