The labopette is a unit manufactured by Hirschmann. It is a fixed, single channel with fixed volume having a conformity certified, with tip ejector and a calibration CE according to IVD 98/79 EG. The steam is sterilizable up to 121 ° C. The unit was supplied with calibration and pipette holder, an individual serial number and calibration certificate. The special tension spring was compared to conventional pipettes. The finger rest provides support for handle safe pipetting with a natural hand position. The tip ejector is separated from pipetting to avoid accidental dropping. The sophisticated ergonomic design of the handle provides small and large hands, right and left handers, hands with or without gloves equally safe and comfortable grip. The effective thermal insulation of the device housing prevents hand heat penetration into the interior.
