Abstract

A pipette device comprises a body with a tip having a distal end suitable for mounting a disposable pipette prong thereon through a compact grating and cooperation mode; a tip ejecting unit used for performing a shift between the distal end of the disposable pipette prong and the upper end of the body along the longitudinal axis direction of the pipette device; and at least one actuator located at the upper end of the body and interacting with the ejecting unit to complete the shift of the tip ejecting unit along the longitudinal axis direction of the pipette device. Said at least one actuator comprises a tappet element connected with the body using a connection point and having a tappet surface with at least one part is vaulted, wherein said tappet surface is suitable for contact with the upper side of the ejecting unit to move the ejecting unit in the direction of the longitudinal axis of the pipette arrangement to eject the disposable tip from the distal end.

Description

technical field [0001] The present invention relates to a suction device comprising: a body with a tip having an end adapted to mount a disposable straw tip thereon in a tight friction fit; ejector means for movement along the longitudinal axis of the device between the end of the disposable straw tip and the upper portion of the body; and located in the upper portion of the body and cooperating with said straw tip ejector means to complete at least one actuating member for said movement. Background technique [0002] Conventional pipette devices for dispensing liquids use disposable pipette tips that are removably mounted to the tip of the pipette device body. Typically, the straw tip is mounted to the tip of the straw device with a tight friction fit. Most straw device embodiments also include means for ejecting their disposable straw tips without manually touching the straw tips. [0003] Finnish Patent No. 57540 discloses a mechanism for ejec...
