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

Pretreatment: Wipe the components of the magnetic base test tube, the straw holder, and the storage tray with a disinfectant to ensure that the magnetic base tube, the straw holder, and the storage tray installed in the clean bench do not change the clean bench. Aseptic environment; if used frequently, it can be placed in the clean bench for a long time, eliminating the sterilization 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 pipette holder: Select the required height, install the horizontal positioning lock of the suction pipe horizontal member, and install it in the same way as the height positioning lock of the horizontal component of the test tube rack; after the height positioning lock is installed, take the horizontal member of the suction pipe frame, The suction pipe connecting sleeve is sleeved into the column, and the lower edge of the connecting sleeve is located at the upper edge of the height positioning lock, and the installation and height positioning of the horizontal member of the suction pipe frame are completed;

Installation of the horizontal member of the storage tray: Select the required height, install the storage box horizontal member height positioning lock, the installation method is the same as the installation of the horizontal height lock of the test tube horizontal member; after the height positioning lock is installed, take the horizontal member of the storage tray, The connecting sleeve of the member is sleeved 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; the installation and height positioning of the horizontal member of the storage tray are completed; the order of the above three horizontal members can be arbitrarily selected according to the experimental needs; The diameter of the inner ring is slightly larger than the outer diameter of the column, so that the connecting sleeve can be freely rotated on the column without causing a significant swing on the column; thus, the magnetic base test tube, the straw holder, and the storage tray have been completed. Installation in a clean bench; for safety reasons, 幵 UV lamp is sterilized twice, after the secondary sterilization is completed, the UV lamp is turned off;

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 that the tube with a small diameter can be inserted vertically into the hanging hole of the tube, and the tube end with a large diameter is stuck above the hanging hole of the tube to ensure the vertical placement of the tube;

Placement of the straw: According to the experiment, rotate and adjust the horizontal position of the straw frame; place the straw vertically or remove the straw from the suction pipe, because the root of the glass pipette will be covered with the latex tip; the root of the disposable plastic pipette is made into the enlarged tip. In part, their diameter is larger than the diameter of the pipette body, so the pipe with a small diameter is inserted into the lower groove of the suction pipe, and the portion of the large diameter is stuck above the hanging groove of the suction pipe, ensuring that the suction pipe is on the test tube rack. Vertical placement, the edge of the hanging groove under the straw has a non-slip baffle plate higher than the suction pipe frame, which prevents the slippery pipe placed in the hanging groove under the suction pipe;

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;

Disassembly: It is necessary to take out the magnetic base test tube, the suction tube holder and the storage tray from the clean platform. In the order from top to bottom, first remove the vertical column upwards and remove the horizontal member of the storage tray, and loosen the positioning lock fastening screw. Move vertically upwards, remove the horizontal member height positioning lock of the storage tray from the column; remove the horizontal member of the suction tube holder and the horizontal member of the test tube rack, the height positioning lock of the horizontal member of the suction tube holder and the height positioning lock of the horizontal member of the test tube holder are the same as above; Spin Turn the switch to the off position and remove the magnetic base.
