Definitions

  • the present invention relates to a storage tray for a clean bench, a straw, a pipette, a syringe holder, and a sterilization tray.
  • Dripper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmology tips, pipettes, pipettes, syringes and culture plates are commonly used experimental tools in scientific research experiments that provide a sterile environment in a clean bench. .
  • the pipette tip, the pipette tip, the alcohol cotton ball, the culture bottle cap, the lighter, the ophthalmology ⁇ are the auxiliary experimental small equipment that need to be used repeatedly in the experiment; the straw is used in the test tube, the reagent bottle, the culture bottle, the beaker, the measuring cylinder Transfer the test solution between the experimental containers such as measuring cups, measuring flasks and flasks; use a pipette (rotary aspiration adjustment dial, preset aspiration volume, and attach the tip) in test tubes, reagent bottles, flasks, beakers, Quantitative transfer of the experimental solution between experimental vessels such as graduated cylinders, measuring cups, measuring flasks and flasks.
  • the experimental solution of different functions can be transferred by simply changing the tip; by using the syringe and the microfilter, a small amount of the solution can be filtered and sterilized. Since the syringe syringe is marked with a scale, the quantitative transfer of the test solution between the test tube, the reagent bottle, the culture flask, the beaker, the measuring cylinder, the measuring cup, the measuring flask and the Erlenmeyer flask can also be achieved by using the syringe; using the culture plate as a container, the cells are used. Carry out experimental operations such as incubation and cultivation.
  • a straw can be reused if it absorbs the same solution. If the straw is placed horizontally, the space occupied by the clean bench is too large. Moreover, in the case where the glass pipette is placed horizontally, it is easy to cause contamination of the straw. This requires people to prepare the vertical placement of the device for the straw in the clean bench.
  • the vertical placement of the straw inside the clean bench is usually accomplished by placing a test tube holder inserted into a sterile test tube on the surface of the clean bench and inserting the pipette vertically into the test tube.
  • 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.
  • Syringes are commonly used as tools in scientific research experiments. In the experiment, a syringe was used multiple times in the clean bench because it was used multiple times when transferring the same experimental solution. The horizontal placement of the syringe on the level of the clean bench will occupy the space of the clean bench, and may also be contaminated by contact of the injector head with other laboratory instruments.
  • culture plates In cell culture experiments, culture plates, especially secondary culture plates, must be aseptically processed. Since the culture plate cannot be autoclaved, the general laboratory does not have the conditions for radiation sterilization. Therefore, it is common to sterilize the culture plate by ultraviolet light irradiation in a clean bench under aseptic conditions. In order to ensure the effect of UV light irradiation, the distance between the UV lamp and the culture plate should be controlled within 30 cm. Therefore, it is necessary to find some objects in the clean bench to raise the culture plate to be close to the light source of the ultraviolet lamp.

After the bacteria are completed, the UV lamp is turned off;
  • Placement of the storage item adjust the horizontal space position of the storage tray horizontally according to the needs of the experiment, wherein the storage object placement board frame (16) surrounds the circular storage object placement board (17) and is higher than the storage surface of the storage object placement board 1cm, used to prevent the falling off of the storage; according to the experiment needs to put or remove the small commonly used small equipment including the pipette tip, the pipette tip, the alcohol cotton ball, the culture bottle cap, the lighter, the ophthalmology ;
  • Placement of the straw According to the experiment, rotate and adjust the horizontal position of the straw frame (20), place the straw slowly under the suction tube (21) or take out the straw, because the root of the glass straw will be covered with latex tip; the root of the disposable plastic straw It will be made into a swollen tip part, the diameter of which is larger than the diameter of the pipe body of the straw; therefore, the pipe body with a small diameter is inserted into the hanging groove of the suction pipe, and the portion of the tip having a large diameter is stuck above the hanging groove of the suction pipe.
  • Placement of the pipette According to the experiment, rotate the horizontal position of the pipette holder plate (25), place the pipette vertically or remove the pipette from the bottom of the pipette (26), because the root of the pipette is facing two Side stretched, so the width is larger than the diameter of the other parts of the pipette; so the pipette part with a small width can be inserted into the lower groove of the pipette, while the root of the pipette with a large width is stuck under the pipette Above the hanging slot, the vertical placement of the pipette on the pipette holder is achieved;
  • Placement of the syringe According to the needs of the experiment, rotate the horizontal position of the syringe holder plate (29), place the syringe horizontally (30) horizontally or remove the syringe;
  • culture plate Placement of plastic cell culture plate (hereinafter referred to as culture plate): According to the experiment, horizontally rotate the plate to position the plate (33) horizontally, and place the plate and the plate cover in a non-slip-off frame (34). In the space, the inner surface of the culture hole and the culture plate cover should face the ultraviolet lamp; the ultraviolet lamp in the clean table is turned on to sterilize them. After the sterilization process is finished, the ultraviolet lamp is turned off, the culture plate cover is covered under aseptic conditions, and the sterilized culture plate is removed from the sterilization tray for use;
  • Disassembly When removing the storage tray, straw, pipette, syringe holder, and sterilization tray with the magnetic base from the clean bench, remove the vertical vertically upwards from the column and remove the sterilization.
  • the horizontal member of the tray loosen the positioning lock fastening screw, move vertically upwards, remove the sterilization tray height positioning lock from the column; remove the syringe, pipette, straw and the horizontal member of the storage tray and remove the horizontal member of the sterilization tray
  • the method is the same; the method of removing the syringe, the pipette, the straw and the storage tray 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. .
