Description

Ultra-static table with magnetic base syringe holder, storage tray, sterilization tray

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

Background technique

[0002] In scientific research experiments in which the clean bench provides a sterile environment, syringes, pipette tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmic files, and culture plates are commonly used in experiments. experiment equipment. Among them, the use of a syringe and a microfilter can achieve filtration and sterilization of a small amount of solution. The use of a syringe (due to the scale on the syringe barrel) enables quantitative transfer of the test solution between the test tube, reagent bottle, culture flask, beaker, graduated cylinder, measuring cup, measuring flask and flask; dropper tip, pipette suction Head, alcohol cotton ball, culture bottle cap, lighter, ophthalmology 镊 are auxiliary laboratory equipment that need to be used repeatedly in the experiment; using the culture plate as a container, the cells are subjected to experimental operations such as incubation and cultivation.

[0003] 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.

[0004] In the need to use dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmology and other experimental small equipment, people usually put these experimental small equipment in the relevant container, or will These experimental small equipment were scattered on the countertop of the clean bench.

[0005] 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, the culture plate is usually sterilized by irradiation with an ultraviolet lamp in a clean bench of 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 plate so that it is close to the light source of the UV lamp.

[0006] However, a syringe is placed on the surface of the clean bench, and the container for storing the experimental small equipment is placed, or the experimental small equipment is directly placed on the surface of the ultra-clean platform, which will occupy the ultra-clean platform. Countertop space, This leads to the crowding of experimental samples, experimental reagents and laboratory equipment on the surface of ultra-clean benches. These phenomena can 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. In the ultra-clean platform, look for some objects to raise the height of the culture plate for UV lamp irradiation and disinfection. Because the ultra-clean table has certain requirements for the placed items, it is more troublesome to find these high-level objects, and there are also obstacles that appear to be unstable. The drop of the culture plate.
