Definitions

  • the invention relates to a magnetic base combined bracket for a clean bench.
  • Test tubes pipette tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmic files, pipettes, pipettes, syringes, and culture plates are commonly used in scientific research experiments that provide a sterile environment in a clean bench. Experimental tool. Among them, the test tube is used as an experimental container to complete the operations of dispensing, extracting, washing, incubating, and replacing the sample; the pipette tip, the pipette tip, the alcohol cotton ball, the culture bottle cap, the lighter, and the ophthalmology are experiments.
  • Auxiliary laboratory equipment that requires multiple uses; use a pipette to transfer the test solution between test vessels, reagent bottles, flasks, beakers, measuring cylinders, measuring cups, measuring flasks, and flasks; use pipettes (rotary aspiration adjustment dials) , preset the amount of liquid absorbed, and install the tip.) Quantitative transfer of the experimental solution between test tubes, reagent bottles, flasks, beakers, measuring cylinders, measuring cups, measuring flasks and flasks. When the different volume of the experimental solution is aspirated, 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.
  • 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.
  • test tube As a test tube, the volume usually has various specifications. In scientific research experiments, these test tubes containing experimental samples often need to be placed vertically in a clean bench to prevent contamination of the experimental sample and spillage of the experimental system. For vertical placement of test tubes of different specifications in a clean bench, it is common to place test tubes on the surface of the clean bench to place the test tubes vertically.
  • 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.
