Description

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

Technical field

The invention relates to a magnetic base storage tray, a straw, a syringe holder and a sterilization tray for a clean bench.

Background technique

In scientific research experiments that provide a sterile environment in a clean bench, dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmic files, pipettes, syringes, and culture plates are experiments that are often used in scientific research experiments. tool. Among them, the pipette tip, the pipette tip, the alcohol cotton ball, the culture bottle cap, the lighter, the ophthalmology 镊 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 The experimental solution is transferred between the experimental containers such as the measuring cup, the measuring flask and the conical flask; and the syringe and the microfilter are used together to filter and sterilize a small amount of the solution. The use of a syringe (due to the scale on the syringe barrel) allows for the quantitative transfer of the test solution between the test tube, reagent bottle, flask, beaker, graduated cylinder, measuring cup, measuring flask and conical flask; using the culture plate as a container, The cells are subjected to experimental operations such as incubation and cultivation.

When you need to use dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmology and other small experimental equipment, people usually put these experimental small devices in the relevant containers, or small these experiments The equipment is scattered on the countertop of the clean bench.

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 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.

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.

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.

However, the test tube rack, the syringe and the container for storing the above experimental small equipment are respectively placed on the table surface of the clean bench, or the above-mentioned experimental small equipment and the syringe are directly placed on the surface of the ultra-clean table, which will occupy the ultra-clean platform. The mesa space leads to the crowding of experimental samples, experimental reagents and laboratory equipment on the clean bench surface. These phenomena can hinder the rapid and efficient implementation of scientific research experiments and affect the accuracy and accuracy of scientific research experiments. In severe cases, it can lead to the failure of scientific research experiments. When looking for some objects in the ultra-clean platform to sterilize the ultraviolet lamp, since the ultra-clean table has certain requirements on the placed items, it is more troublesome to find these high-level objects, and sometimes the high-quality objects are unstable. The board fell.
