Description

Technical Field

[0001] The utility model relates to the field of cell culture, in particular to a plate-type defoamer. Background Art

[0002] Cell culture is a technique for growing and multiplying living cells under controlled conditions in a laboratory. By providing the appropriate nutrients, temperature, humidity, and gas environment, cells can continue to grow and divide in a culture dish or flask. Cell culture is commonly used in biomedical research, drug screening, biopharmaceuticals, and other fields.

[0003] Cell culture dishes are common laboratory utensils used for cell culture. During the cell culture process, air bubbles may be introduced during liquid transfer, stirring or pipetting. These bubbles will form foam in the culture medium. Some components in the culture medium or colloid substances secreted by the bacteria themselves may increase the viscosity of the liquid and also form foam. Therefore, foam is usually produced by bubbles and colloids.

[0004] Most existing solutions to foaming foam involve adding anti-foaming agents to the culture medium or removing it manually using pipettes such as pipettes. The process is cumbersome and requires delicate operation, which affects efficiency.

[0005] Therefore, a plate type demister which is easy to operate is provided to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 3 The utility model provides a technical solution: a plate-type demister, the demister comprises a demister plate 1, a filter bag 2 which is clamped under the demister plate 1 and maintains a gap with the demister plate 1, an unlocking mechanism 3 arranged on the demister plate 1 for removing the filter bag 2, and a hand-held rod 4 arranged above the demister plate 1, wherein the filter bag 2 is arranged as a filter membrane in the shape of an inverted cone.

[0027] When in use, the foam removal plate 1 and the filter bag 2 are moved to the cell culture dish by means of the hand-held rod 4, and the filter bag 2 is pressed into the liquid surface of the culture dish from top to bottom. Since the filter bag 2 is in the shape of an inverted cone, the floating foam will gradually diffuse to the surroundings as the filter bag 2 penetrates into the liquid surface, until the top of the filter bag 2 also sinks into the liquid surface, and the floating foam flows into the filter bag 2 from the top edge of the filter bag 2 along with the culture solution, until the floating foam completely flows into the filter bag 2, the filter bag 2 is pulled upward by means of the hand-held rod 4 to be taken out, and the culture solution in the filter bag 2 is filtered and precipitated under the action of gravity, while the floating foam is retained on the inner side of the filter bag 2, thereby quickly completing the filtration.

[0028] Furthermore, a connecting seat 11 is provided at the center of the side of the defoaming plate 1 away from the filter bag 2, and the end of the hand-held rod 4 close to the defoaming plate 1 is screwed to the connecting seat 11; by tightening the hand-held rod 4 on the connecting seat 11, the hand-held rod 4 is connected to the defoaming plate 1. When disassembling, it is only necessary to twist the hand-held rod 4 in the opposite direction to facilitate subsequent cleaning or replacement.

[0029] It should be noted that the filter bag 2 is fixedly connected with an elastic clamp 21 at a symmetrical position close to one side of the defoaming plate 1, and a through groove 12 for inserting and locking the elastic clamp 21 is opened at a position on the defoaming plate 1 corresponding to the elastic clamp 21, and the elastic clamp 21 has a limit block with a width greater than the diameter of the through groove 12; the filter bag 2 is inserted into the through groove 12 of the defoaming plate 1 through the elastic clamp 21, and the clamping part of the elastic clamp 21 after insertion is reset and clamps the top surface of the defoaming plate 1 to prevent the filter bag 2 from falling off. At the same time, the limit block on the elastic clamp 21 can also maintain the gap between the defoaming plate 1 and the filter bag 2, which is convenient for the culture medium to enter the filter bag 2 from the side gap during defoaming.

[0030] When the filter bag 1 is unlocked, the top of the filter bag 31 is pressed down and the filter bag 33 is in a state of being pushed and pulled out of the filter bag 33. When the filter bag 1 is unlocked, the top of the filter bag 31 is pressed down and the filter bag 33 is in a state of being pushed and pulled out of the filter bag 33.

[0031] Furthermore, there are limit rods 22 at the symmetrical positions between the two elastic clamps 21 on the filter bag 2, and a limit groove 14 is provided at the position corresponding to the limit rod 22 on the defoaming plate 1; when the filter bag 2 is installed on the defoaming plate 1, the limit rod 22 on the filter bag 2 will also be inserted into the defoaming plate 1 through the limit groove 14, thereby cooperating with the two elastic clamps 21 to form a four-point support of a circular array on the defoaming plate 1, thereby making the connection between the filter bag 2 and the defoaming plate 1 more stable.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
