[Claim 5] The magnetic base test tube, the pipette holder, and the storage tray for the clean bench according to claim 4. Its characteristics are: How to use:

Pretreatment: Wipe the parts of the magnetic base test tube, the pipette holder, and the storage tray with a disinfectant to ensure that the magnetic base test tube, pipette holder, and storage tray installed in the clean bench do not change. The aseptic environment in the clean bench; if it is used frequently, it can be placed in the ultra-clean bench for a long time, which can be wiped out and disinfected 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;

Pipette horizontal member installation: Select the required height, install the pipette horizontal member height positioning lock, the installation method is the same as the test tube horizontal member height positioning lock; after the height positioning lock is installed, take The pipette frame horizontal member, the pipette frame connecting sleeve is sleeved 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 pipette holder is installed and positioned; the horizontal member of the storage tray Installation: Select the required height, install the storage tray horizontal member height positioning lock, the installation method is the same as the test tube horizontal member height positioning lock installation method; after the height positioning lock is installed, take the storage tray horizontal member, the member Connection sleeve Into the column, the lower edge of the connecting sleeve is located at the upper edge of the height positioning lock to complete the height positioning; complete the installation and height positioning of the horizontal member of the storage tray;

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 without being allowed to The shaft has a significant swing; at this point, the installation of the magnetic base test tube, the pipette holder and the storage tray in the ultra-clean station has been completed; for the sake of safety, the UV lamp is sterilized twice, after the secondary sterilization is completed, 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 pipette: Depending on the experiment, rotate the horizontal position of the pipette holder; place the pipette vertically or remove the pipette from the bottom of the pipette, as the root of the pipette extends to the sides

Therefore, the width is larger than the diameter of other parts of the pipette; therefore, the pipette portion with a small width can be inserted into the lower groove of the pipette, and the root of the pipette with a large width is stuck in the groove under the pipette. Above, the vertical placement of the pipette on the pipette holder is achieved;

Placement of storage items: Adjust the horizontal space position of the storage tray horizontally according to the needs of the experiment.

Wherein, the storage object placing board frame surrounds the circular storage object placing board, and is higher than the board surface of the storage object placing board by lcm, for preventing the falling of the storage object; placing or taking out the experiment on the storage object placing board according to the experiment requirement Commonly used small equipment;

Disassembly: The magnetic base test tube, pipette holder and storage tray are removed from the clean bench. In the order from top to bottom, the vertical member is removed vertically and removed from the column. The horizontal member of the storage tray is removed. Screw, move up vertically, remove the storage tray horizontal member height positioning lock from the column; remove the pipette holder horizontal member and the test tube rack horizontal member, pipette holder horizontal member height positioning lock and test tube rack horizontal member height positioning lock operation Same as above; Finally, rotate the constant magnet to the closed position and take out the magnetic base.
