Positioning lock fastening screw, moving vertically upwards, removing the pipette holder height positioning lock from the column; removing the straw holder horizontal member, the storage tray horizontal member and the test tube rack horizontal member, and removing the pipette holder horizontal member The method is the same, the method of removing the straw holder height positioning lock, the storage tray height positioning lock and the test tube rack height positioning lock is the same as the method of removing the pipette holder height positioning lock; finally, the constant magnet rotary switch is turned to the off position. Take out the magnetic base.

Abstract

L'invention concerne une éprouvette à socle magnétique, un plateau de rangement, un tube d'aspiration et un support de pipettes utilisé pour un banc super stérile. Une surface latérale d'un support magnétique (6) est une surface (4) d'attraction du support magnétique qui attire une base magnétique (6) sur une plaque en fer à bord vertical à l'intérieur du banc super stérile. Une surface inférieure (7) du support magnétique est en contact avec une surface inférieure à l'intérieur du banc super stérile. Une plaque (3) de base de colonne verticale est montée de manière fixe au niveau d'une surface supérieure du support magnétique (6), et une colonne verticale (1) est disposée sur la plaque (3) de base de colonne verticale. Quatre verrous de positionnement de hauteur de l'élément horizontal sont disposés sur la colonne verticale (1); et un élément horizontal du support d'éprouvette, un élément horizontal du plateau de rangement, un élément horizontal du tube d'aspiration et un élément horizontal du support de pipettes, qui sont gainés sur la colonne verticale (1) et peuvent tourner horizontalement sur la colonne verticale (1), sont agencés au-dessus des quatre verrous de positionnement de hauteur de l'élément horizontal, respectivement.
