Description

Ultra-clean table with magnetic base storage tray, sterilization tray

Technical field

The invention relates to a magnetic base storage tray 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, and ophthalmologists are experimental small devices that are commonly used in experiments. 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 equipment in the relevant container, or the above experiment is small The equipment is scattered on the countertop of the clean bench.

In the cell culture experiment, when the culture plate is used as a container and the cells are subjected to an experimental operation such as incubation and culture, the culture plate, particularly the secondary use plate, 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, placing the containers containing the experimental small equipment horizontally on the table surface of the ultra-clean platform, or directly arranging these small devices on the surface of the ultra-clean platform, will occupy the table space of the ultra-clean platform, resulting in the ultra-clean platform. The crowded phenomenon of experimental samples, experimental reagents and laboratory equipment appearing on the countertops will 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 UV lamp, since the ultra-clean table has certain requirements for the placed items, it is more troublesome to find these high-level objects, sometimes there are pads. High material instability leads to the fall of the culture plate.
