  • Pipettes are used as tools for quantitative transfer of solutions in scientific research experiments. The frequency of use is very high. Sometimes pipettes with a tip are used repeatedly when drawing the same test solution. Since the liquid level of the clean bench occupied by the pipette is too large, and the liquid pipette has been sucked, the liquid remaining in the suction head may flow to the pipette and the tip connection portion. Causes contamination of the pipette. This requires people to prepare a vertically placed pipette holder for the pipette in the clean bench. To ensure the stability of the pipette holder after placing the pipette, the pipette holder generally has a larger base area.

  • Disassembly When removing the magnetic base test tube, storage tray, pipette holder, and sterilization tray from the clean bench, in the order from top to bottom, first vertically remove the column from the column and remove the horizontal component of the sterilization tray. Open the positioning lock fastening screw, move it vertically upwards, remove the sterilization tray height positioning lock from the column; remove the pipette holder horizontal member, the storage tray horizontal member and the test tube rack horizontal member, and the method of removing the sterilization tray horizontal member Similarly, the method of removing the pipette 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 sterilization tray height positioning lock; finally, the constant magnet rotary switch is turned to the off position, and the magnetic is taken out.

Abstract

Un tube à essai à base magnétique, un plateau de stockage, un support de pipette et un plateau de stérilisation pour un banc super propre sont décrits. Le banc super propre comprend une base magnétique (6) qui génère une force magnétique d'adsorption. La surface latérale de la base magnétique (6) est une surface d'adsorption de base magnétique (4) qui adsorbe la base magnétique (6) sur une plaque latérale verticale en fer dans le banc super propre. La surface inférieure (7) de la base magnétique est en contact avec la surface inférieure dans le banc super propre. La surface supérieure de la base magnétique (6) est pourvue de manière fixe d'un châssis de colonne verticale (3). Une colonne verticale (1) est disposée sur le châssis de colonne verticale (3). La colonne verticale (1) est pourvue de quatre verrous de positionnement en hauteur d'élément horizontal, et d'un élément horizontal de support de tube à essai, d'un élément horizontal de plateau de stockage, d'un élément horizontal de support de pipette, et un élément horizontal de plateau de stérilisation qui sont emmanchés sur la colonne verticale (1) et qui peuvent tourner horizontalement sur la colonne verticale (1) sont respectivement disposés au-dessus des quatre verrous de positionnement en hauteur d'élément horizontal.
