Definitions

  • the invention relates to a test tube for a clean bench, a storage tray, a straw, a pipette and a syringe holder.
  • Test tubes dropper tips, pipette tips, alcohol swabs, culture caps, lighters, ophthalmic files, pipettes, pipettes, and syringes are commonly used experimental tools in scientific research that provides a sterile environment in a clean bench. 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 using a syringe.
  • Test tubes are used as experimental containers and the volume is usually available in a variety of sizes. 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 order of installation of the above five 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 A significant swing is generated on the column; thus, the installation of the test tube, the storage tray, the straw, the pipette, and the syringe holder having the magnetic base has been completed; for the sake of safety, the ultraviolet lamp is double-sterilized, and after the secondary sterilization is completed , off the UV lamp;
  • test tubes Placement of plastic micro-tubes with cover (hereinafter referred to as test tubes): According to the needs of the experiment, adjust the horizontal position of the test tube rack plate (17); according to the specifications of the test tubes, select the vertical placement or take-out of the test tube under the different specifications (16). In the test tube, since the diameter of the tube end of the tube is larger than the diameter of the tube body, the tube with a small diameter can be vertically inserted into the hanging hole of the tube, and the tube end with a large diameter is stuck above the tube under the tube to ensure The vertical placement of the test tube;
  • 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 (20) surrounds the circular storage object placement board (21) 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 (24); place the straw slowly under the suction tube (25) 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 an enlarged tip part, and their diameter is larger than the diameter of the straw body; therefore, the tube with a small diameter is inserted into the hanging groove of the straw, and the part of the diameter of the head is stuck above the hanging groove of the straw.
  • Pipette placement Depending on the experiment, rotate the horizontal position of the pipette holder plate (29); place the pipette vertically or remove the pipette from the pipette down slot (30), as the root of the pipette is oriented 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 Rotate the horizontal position of the syringe holder plate (33) according to the needs of the experiment; place the syringe horizontally (34) horizontally or remove the syringe;
  • Disassembly When removing the test tube, storage tray, straw, pipette, and syringe holder with the magnetic base from the clean bench, remove the vertical frame from the column and remove the horizontal member of the syringe holder in the order from top to bottom. Loosen the positioning lock fastening screw and move it vertically upwards to remove the syringe holder height positioning lock from the column; the method of removing the pipette, the suction tube, the storage tray and the horizontal component of the test tube holder is the same as the method of removing the horizontal member of the syringe holder.
  • the method of removing the pipette, the suction pipe, the storage tray and the test tube holder height positioning lock is the same as the method of removing the syringe holder height positioning lock; finally, the constant magnet rotary switch is turned to the off position, and the magnetic base can be taken out.
