Abstract (en)
[origin: EP0455043A2] A pipetting device has a housing, at the upper end of which there projects an activation element which can be pressed in counter to a spring action. This activation element is connected by means of a rod system to a piston which can be moved in a cylinder in order to move an air volume. The cylinder communicates with an opening of a connection piece, in particular a connection cone, for attachable pipette teats which are open at the top and bottom. The piston 10 is designed as a hollow piston with an outer tubular skirt 23, which is held on an inner support 9 which is made especially of plastic and which is in communication with the activation element. It is possible to provide skirts 23 which are made of different materials and are exchangeable. <IMAGE>
