PURPOSE:To prevent a large load from being placed on a supply device at the time of nose insertion by pressing up a pipette tip together with a holder by using an elevation mechanism and inserting it into a pipette nose, and receiv ing its inserting force by a link mechanism. CONSTITUTION:The elevation mechanism A1 provided to the pipette tip supply device A elevates a pressing-up rod A2 to press up the pipette tip A4 together with the holder A3, thereby applying the inserting force P to the pipette chip A4. This inserting force is applied to the pipette nose B1 of a pipette unit B, but a link mechanism A5 where the pipette holder B2 united with the nose B1 is fixed to the pipette supply device A functions as a projection rod to press it, so said inserting force P is received by the link mechanism A5, thereby preventing the inserting force from being applied to the unit B. Then the inserting force P received by the link mechanism 5 is canceled with the reaction R of the inserting force of a rod A2 applied to the elevation mechanism A1, so a large load is prevented from being placed on the pipette tip supply device A. |
