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.

Claims (5)

1 . Electronic piston stroke pipette, comprising a pipette cone, in which a mobile piston is rigidly connected via a piston rod with a transmission for its upward and downward movement, in which context the transmission is driven by a drive motor, wherein the control board comprises an upper part as 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.

2 . Electronic piston stroke pipette according to claim 1 , wherein the control board comprises plastic, preferably polypropylene, ABS or POM, or metal.

3 . Electronic piston stroke pipette according to claim 1 , wherein the upper part of the control board is round or polygonal in shape, preferably 6-9 edged.

4 . Electronic piston stroke pipette according to claim 1 , wherein the upper part of the control board has a diameter of 18-22 mm, preferably 19 mm, and the thickness amounts to 7-9 mm, preferably 8 mm.

5 . Electronic piston stroke pipette according to claim 1 , wherein the lower part of the control board is cylindrical in shape and manifests a diameter of 10-25 mm, preferably 11 mm.
