Cell refrigeration constant-temperature test bed

Abstract

The invention relates to the technical field of cell culture, and discloses a cell refrigeration constant-temperature test bed, which comprises a workbench, a bearing, an incubator, a clamping assembly, an object taking assembly and a base, the bottom end of the inner wall of the workbench and the outer wall of the bottom end of the bearing are fixedly installed, and the inner wall of the bottom end of the incubator and the inner wall of the bearing are fixedly installed; the outer wall of the clamping assembly is movably connected with the inner wall of the incubator, according to the cell refrigeration constant-temperature test bed, a culture dish is placed in the incubator by a user, fixed placement of the culture dish is achieved under the action of the clamping assembly, the base andthe gravity of the culture dish, the incubator is rotated to align the required culture dish with a membrane sealing table under the action of the bearing, then a sleeve rod is pressed to drive an arc-shaped toothed plate to rotate, and the rotation of a gear is matched with other mechanisms of the object taking assembly to realize the upward movement of the culture dish, so that the cell refrigeration constant-temperature test bed is realized, and rapid membrane sealing is realized when the culture dish is taken out; and secondary infection is avoided.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to a cell refrigeration constant temperature test bench. Background technique [0002] Cell cryopreservation is one of the main methods of cell preservation. The use of cryopreservation technology to store cells in liquid nitrogen at -196°C can temporarily detach the cells from the growth state and preserve their cell characteristics, so that they can be stored again when needed. Resuscitated cells are used in experiments, and a certain amount of cells are preserved moderately, which can prevent the cells from being lost due to contamination of the cells being cultured or other accidents, and play a role in cell conservation. In addition, it can also be used The form of cell cryopreservation is used to purchase, send, exchange and transport certain cells. During the passage and daily maintenance of cell culture, a lot of consumption is required in terms of culture equipment, cu...

Problems solved by technology

[0003] Currently on the market, most of the cells are kept at constant temperature during the culture process. This way of preservation is beneficial to the growth of the cells. At the same time, the refrigerated stage can well ensure the growth of other polluting bacteria and reduce the experimental error. When the dish is taken out, in order to prevent bacteria in the air from entering the Petri dish, it is necessary to seal the outer wall of the Petri dish. The traditional way is to seal the film manually, which is cumbersome, and the exposure time of the Petri dish in the air is longer. , easy to cause pollution, so a cell refrigeration constant temperature test bench is needed, which has the effect of quickly sealing the membrane when accessing the cells
