Sampling pipette with control member that has two functions of unlocking the volume adjustment system and cone ejection

摘要

In order to improve the ergonomics of the sampling pipette, according to the present invention, the control is configured such that the spring (60) takes the neutral position to bring the lock member (46) to the lock position for adjusting the sampling amount. A member (25) is provided. The control member (25) is displaced from the neutral position in the axial direction, and a lower cone ejection position where the control member (25) presses the cone ejector (20) and an upper position where the brake ring (40) is unlocked. It is possible to take the unlocking position. The movement from the neutral position to the cone ejection position is performed against the biasing force of the spring (32). Movement from the neutral position to the unlock position moves the lock member (46) to the disengagement element (70) against the biasing force of the spring (60) until the brake ring (40) is released.
