Description

Ultra-clean table with magnetic base straw, syringe holder, storage tray

[0001] The present invention relates to a magnetic base suction pipe, a syringe holder, and a storage tray for a clean bench.

Background technique

[0002] Pipettes, syringes and dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmologists are the experimental equipment commonly used in experiments in scientific research experiments that provide a sterile environment in a clean bench. . Among them, the test solution is transferred between test tubes, test tubes, reagent bottles, culture flasks, beakers, measuring cylinders, measuring cups, measuring flasks, and flasks using a pipette; and a small amount of solution can be filtered and sterilized by using a syringe and a microfilter. Since the syringe barrel 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 can also be achieved using a syringe; the pipette tip and the pipette tip , alcohol cotton balls, culture bottle caps, lighters, ophthalmology 镊 are auxiliary laboratory equipment that needs to be used repeatedly in experiments.

[0003] Straws As a tool often used in scientific research experiments, 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 likely 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 with a sterile test tube on the surface of the clean bench and inserting the pipette vertically into the test tube.

[0004] 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 after transferring the same experimental solution. The level of the syringe on the level of the clean bench can be used to occupy the surface space of the clean bench, and it may be contaminated by the contact of the injector head with other laboratory instruments.

[0005] In the need to use dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmology and other experimental equipment, people usually put these experimental equipment in the relevant containers, or will These experimental small equipment were scattered on the countertop of the clean bench.

[0006] However, the test tube rack, the syringe and the container for accommodating the above experimental small equipment are respectively placed on the table surface of the clean bench, or the above experimental small equipment is directly placed on the table surface of the ultra-clean table, which will occupy a large excess. Clean bench The surface space causes crowding of experimental samples, experimental reagents, and laboratory equipment on the surface of a clean bench where the original area is not large. The crowding of experimental samples, experimental reagents and laboratory equipment on the surface of ultra-clean benches will hinder the rapid and efficient implementation of scientific research experiments and affect the accuracy and accuracy of scientific research experiments. Serious paralysis can lead to the failure of scientific research experiments.

[Claim 5] The magnetic base suction pipe, the syringe holder, and the storage tray for the clean bench according to claim 4, wherein:

Pretreatment: Wipe the parts of the magnetic base pipette, syringe holder and storage tray with disinfectant to ensure that the magnetic base pipette, syringe holder and storage tray installed in the clean bench will not change the clean bench. Aseptic environment; if used frequently, it can be placed in the clean bench for a long time, and can be wiped 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 member of the pipette holder: Select the required height and install the height adjustment lock of the horizontal member of the suction pipe holder; the specific steps are as follows: Loosen the positioning lock fastening screw, insert 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 member of the suction tube holder, and fit the suction tube connection sleeve into the column, and connect the lower edge of the sleeve. Located at the upper edge of the height-positioning lock, completes the installation and height positioning of the horizontal components of the pipette holder;
