[Claim 5] The magnetic base test tube rack, the storage tray, and the sterilization tray for the clean bench according to claim 4.

, its characteristics are: How to use:

Pretreatment: Wipe the components of the magnetic base test tube, the storage tray, and the sterilization tray with a disinfectant to ensure that the magnetic base test tube, storage tray, and sterilization tray installed in the clean bench do not change the clean bench. Sterile environment inside; if it is used frequently, it can be placed in the clean bench for a long time, which can be wiped out by disinfection with disinfectant;

Installation of the magnetic base: Rotate the constant magnet to the closed position. Then, the N and S poles of the constant magnet are in a horizontal position, and the magnetic lines of force form a closed circuit in the two soft magnetic materials separated by the non-magnetic material. The magnetic seat adsorption surface is not magnetic and can move freely; the magnetic base is placed at the desired position, and the specific operation is as follows: the magnetic seat adsorption surface is in contact with the iron vertical vertical plate in the ultra-clean platform, the magnetic base bottom surface and the ultra-clean platform The bottom surface contacts; the rotating constant magnet rotates to the position of the crucible, the N and S poles of the constant magnet are in the upper and lower positions, and the N and S poles of the constant magnet are respectively aligned with the two soft magnetic materials separated by the non-magnetic material. From the N pole to the soft magnetic material to the iron vertical side plate in the ultra clean table to another soft magnetic material to the S pole, forming a magnetic line close, the magnetic seat adsorption surface can be firmly adsorbed in the iron in the ultra clean table Vertical vertical board;

Installation of the horizontal component of the test tube rack: Select the required height, install the height adjustment lock of the horizontal height of the test tube rack; the specific steps are as follows: Loosen the positioning lock fastening screw, put the cylindrical hole in the middle of the positioning lock into the column, select the desired Height, tighten the positioning lock fastening screw, so that the silicone pad of the positioning lock is tightly engaged with the column; after the height positioning lock is installed, take the horizontal component of the test tube rack, put the test tube bracket into the column, and connect the lower edge of the sleeve Located at the upper edge of the height positioning lock, completing the installation and height positioning of the horizontal components of the test tube rack;

Installation of the horizontal member of the storage tray: Select the required height, install the horizontal member height positioning lock of the storage tray, and install the same method as the height adjustment lock of the horizontal member of the test tube rack; after the height positioning lock is installed, take the horizontal member of the storage tray The connecting sleeve of the component is sleeved into the column, and the lower edge of the connecting sleeve is located at the upper edge of the height positioning lock to complete the height positioning; the installation and height positioning of the horizontal member of the storage tray are completed;

Installation of the horizontal components of the sterilization tray: Select the required height, install the horizontal position lock of the horizontal position of the sterilization tray, and the installation method is the same as the installation method of the height adjustment lock of the horizontal member of the test tube rack. After the height positioning lock is installed, take the horizontal part of the sterilization tray, and put the sterilization tray connecting sleeve into the column. The lower edge of the connecting sleeve is located at the upper edge of the height positioning lock, and the horizontal member of the sterilization tray is installed. Height positioning; The order of installation of the above three horizontal members can be arbitrarily selected according to the needs of the experiment; the diameter of the inner ring of the connecting sleeve is slightly larger than the outer diameter of the column, so that the connecting sleeve can be freely rotated on the column, and cannot Let it produce a clear swing on the column; At this point, the installation of the magnetic base test tube, the storage tray, and the sterilization tray in the ultra-clean station has been completed; for the sake of safety, the UV lamp is twice sterilized, after the secondary sterilization is completed , turn off the UV lamp;

Placement of plastic micro-tubes with cover: According to the experiment, rotate and adjust the horizontal position of the tube rack plate; according to the specifications of the test tube, select the vertical placement of the tube under the test tube of different specifications or take out the test tube, because the diameter of the tube end of the test tube is larger than The diameter of the tube body, so the tube with small diameter can be inserted vertically into the hanging hole of the tube, while the tube end with large diameter is stuck above the tube hanging hole, which ensures the vertical placement of the tube on the tube rack;

Placement of the storage item: According to the needs of the experiment, the horizontal space position of the storage tray is adjusted horizontally, wherein the storage object placement board frame surrounds the circular storage object placement board and is higher than the board surface of the storage object placement board, and is used for preventing storage. The falling off of the object; according to the experiment needs to put or take out the small equipment commonly used in the experiment on the storage placing board;

Placement of plastic cell culture plate: According to the experiment, rotate the plate horizontally to position the plate horizontally, place the plate and the plate cover into the space surrounded by the non-slip frame, the culture hole and the inner surface of the plate cover. Face the UV lamp; sterilize the UV lamp in the clean room; after the sterilization process, turn off the UV lamp, cover the plate cover under sterile conditions, and take it from the sterilization tray. The sterilized culture plate is ready for use. Disassembly: The magnetic base test tube, storage tray and sterilization tray 需要 need to be taken out from the clean bench. In the order from top to bottom, first vertically remove the column and remove the sterilization. Horizontal member of the tray, loose positioning lock fastening screw, moving vertically upwards, removing the horizontal member height positioning lock from the column; taking out the storage tray horizontal member and the test tube rack horizontal member, the storage tray horizontal member height positioning lock and the test tube rack horizontal member The operation of the height positioning lock is the same as above; finally, the constant magnet is rotated and turned to the closed position, and the magnetic base can be taken out.
