Abstract: The invention relates to a functional part of an electronic piston stroke pipette with an operating environment adapted to manual piston stroke pipettes. The piston stroke pipette according to the invention comprises a pipette cone, in which there is a movable piston, rigidly connected with a transmission for its upwards and downwards movements via a piston rod, in which context the transmission is propelled by a drive motor and wherein the control board comprises an upper part as the operating part for turning and pressing and a bar as a cylindrical connection to the electronics, with the control board and display integrated in the display housing in the upper part and drive motor and battery (rechargeable battery) in the lower part of the pipette housing. Fields of application of the invention are analytical chemistry and medicinal diagnostics.

Abstract: The invention relates to a new multiwell filtration plate for high throughput applications in nucleic acid technology, preferably in a 96-well or 384-well format, consisting of two individual parts, which are firmly and tightly connected together. The upper part of the plate is a sample holder 1 for holding a sample to be filtered. The lower part of the plate is an outlet part with a filter insert for receiving a sample from the sample holder part and filtering the, sample through the filter insert.
