  • Placement of plastic cell culture plate According to the experiment, horizontally rotate the plate to position the plate (29) horizontally, and place the plate and the plate cover into the space surrounded by the non-slip frame (30). And the inner surface of the culture plate cover should face the ultraviolet lamp; turn on the ultraviolet lamp in the ultra-clean table to sterilize them; after the sterilization process is finished, turn off the ultraviolet lamp, and cover the culture plate cover under aseptic conditions. Remove the sterilized culture plate from the sterilization tray and set aside;
  • Disassembly When removing the magnetic base test tube, storage tray, suction tube holder, and sterilization tray from the clean bench, remove the vertical member from the column and remove the horizontal member of the sterilization tray in the order from top to bottom, and loosen the positioning. Lock the fastening screw, move it vertically upwards, and take out the sterilization tray height positioning lock from the column; the method of taking out the suction tube horizontal member, the storage tray horizontal member and the test tube horizontal member is the same as the method of removing the sterilization tray horizontal member, and the straw is taken out. The method of height positioning lock, storage tray height positioning lock and 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 base can be taken out.

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. Le banc super stérile comprend une base magnétique (6) pour générer une force d'attraction magnétique; une surface latérale de la base magnétique (6) est une surface d'attraction de base magnétique (4) pour fixer la base magnétique (6) à une plaque latérale verticale en fer à l'intérieur du banc super stérile; et une surface inférieure (7) de la base magnétique est en contact avec une surface inférieure à l'intérieur du banc super stérile. Un socle de colonne (3) est monté de manière fixe sur la base magnétique (6), et une colonne (1) est disposée sur le socle de colonne (3). La colonne (1) est pourvue de quatre verrous de positionnement en hauteur d'élément horizontal. Un élément horizontal pour un support d'éprouvettes, un élément horizontal pour plateau de rangement, un élément horizontal pour tube d'aspiration et un élément horizontal pour support de pipettes stérile, sont montés sur la colonne (1) et peuvent tourner horizontalement sur celle-ci, et sont respectivement disposés sur les quatre sièges de positionnement en hauteur horizontaux. Le dispositif possède une structure rationnelle, et est facile à utiliser et comporte un emplacement de positionnement réglable.
