Abstract

The invention discloses a sterilizable assembly bracket for a sterile operation experiment, and relates to a supporting device in microorganism and cell culture experiments, aiming at solving the problem that the accuracy of a test result is affected since the conventional inoculation ring and coater are required to be held in hand to cool after being subjected to dry heat sterilization by using an alcohol lamp and the temperature of an evaporated and sterilized culture medium can only be judged empirically. The sterilizable assembly bracket comprises a border, stop wires, connecting pieces, a bottom frame, heat-resistant rods, connecting rings, a temperature display control unit and N temperature sensors, wherein the border is connected with the bottom frame through the connecting pieces; the opposite surfaces of the border and the bottom frame are provided with a plurality of stop wires; the two ends of each heat-resistant rod are correspondingly arranged on the symmetric strop wires respectively; the upper surface of the bottom frame is provided with a plurality of connecting rings; the two ends of the heat-resistant rods are correspondingly arranged in the symmetric connecting rings respectively; the N temperature sensors are communicated with the temperature display control unit. The sterilizable assembly bracket is applicable to the supporting device for vertical cell culture of a square culture vessel in the cell culture experiment.

Description

technical field [0001] The present invention relates to support devices in microbiological and cell culture experiments. Background technique [0002] At present, the inoculation ring and applicator in the ultra-clean workbench are placed flat on the table. During the experimental operation, after dry heat sterilization with an alcohol lamp flame, it needs to be held in the hand until it cools down, which is inconvenient to use; especially When inoculating multiple bacteria or coating different plates, it is necessary to perform flame dry heat sterilization one after another, which is very time-consuming. The temperature of the burnt inoculation loop, applicator, and steam-sterilized medium can only be judged by experience, and sometimes inaccurate judgments affect the test results, which seriously affects the test efficiency. In addition, there is no effective support for the vertical cultivation of the square culture dish in the incubator. Contents of the invention [...
