The pipetting assistant maneus® was designed for easy and tireless handling of liquids in the laboratory for left and right-handed persons. An especially shaped intake cone allows the use of pipettes from 0.1 mL to 100 mL while the volume is selected precisely with the highly sensitive meniscus. The perfectly harmonized valve unit ensures effortless liquid intake. A replaceable hydrophobic membrane filter protects the interior from penetrating liquids. All parts and pieces may be replaced individually, allowing for a long lifetime of the instrument. The maneus® is completely autoclavable.
