Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cell culture, in particular to a simple humidifying device suitable for a carbon dioxide incubator. Background Art
[0002] The CO2 incubator is an essential precision culture equipment for cell biology research, suitable for the culture of cells and tissues. Thanks to its precise temperature, CO2, pH and humidity control, it can simulate the growth environment of cells or tissues in vivo in vitro, making a significant contribution to biological research.
[0003] However, since cells are cultured in a liquid environment, humidity is not a culture parameter that must be strictly controlled. It indirectly affects cell growth by affecting the evaporation rate of water in the culture medium. Many incubators on the market simply humidify by placing a water tray and do not provide humidity monitoring. This type of carbon dioxide incubator maintains a high humidity in the box by evaporating water in the water tray. However, practice has shown that this method has limited moisturizing effect. For example, the Thermo 311 carbon dioxide incubator commonly used in laboratories uses water tray evaporation for humidification. The edge wells of a 96-well plate are almost dried up after culturing cells for about 3 weeks, and the time required for cell line formation is usually 3 to 4 weeks, which means that the edge 36 wells cannot be used to culture cells, greatly compromising the throughput advantage of the 96-well plate. The price of an incubator with active humidity control is significantly higher than that of the above-mentioned incubators. Therefore, it is of certain significance to make low-cost improvements to this type of water tray humidity control incubator. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a simple humidifying device with simple structure, convenient use and good humidifying effect.
[0005] In order to achieve the above purpose, a simple humidification device suitable for a carbon dioxide incubator is designed, including a water tray of the carbon dioxide incubator and a stainless steel bracket. The stainless steel bracket includes a plurality of support frames arranged in a front-to-back direction. The plurality of support frames have the same shape and size, are concave in shape, and have support angles at two sections. The device also includes two connecting pieces for connecting the plurality of support frames at the same time.
[0006] The utility model also has the following preferred technical solutions:
[0007] 1. The plurality of support frames arranged in the front-to-back direction are arranged at equal intervals.
[0008] 2. The stainless steel bracket is placed across the water tray of the carbon dioxide incubator, and the absorbent paper or wet and dry towel is hung on the stainless steel bracket, with the bottom of the absorbent paper or wet and dry towel contacting the water surface in the water tray of the carbon dioxide incubator.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] After using the utility model, the humidity of the incubator increases, and the cell culture fluid has no risk of drying out. Moreover, by controlling the number of paper towels hung, the evaporation area can be adjusted, thereby roughly controlling the humidity. In this way, the moisturizing effect is improved at a very low cost without replacing the active humidity control incubator. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings. The structure and principle of the utility model are very clear to people in the field. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] like Figure 3 , 4 As shown, the utility model is a simple humidifying device suitable for a carbon dioxide incubator, comprising a carbon dioxide incubator water tray 5 and a stainless steel bracket 1.
[0018] like Figure 1 As shown, the stainless steel bracket 1 includes a plurality of support frames 2 arranged in a front-to-back direction, the plurality of support frames 2 have the same shape and size, are in a concave shape, and are provided with support angles 3 at two sections, the plurality of support frames 2 arranged in a front-to-back direction are arranged at equal intervals, and the two ends of the plurality of support frames 2 are connected by two connecting pieces respectively.
[0019] like Figure 2 , 4 As shown, the stainless steel bracket 1 spans over the water tray 5 of the carbon dioxide incubator, and the absorbent paper or wet and dry towel 4 is suspended on the stainless steel bracket 1, and the bottom of the absorbent paper or wet and dry towel 4 contacts the water surface in the water tray 5 of the carbon dioxide incubator.
[0020] The stainless steel bracket 1 does not rust when in contact with water for a long time. The bottom of the bracket is designed with a curved support angle 3, which is stable. After the stainless steel bracket 1 is placed above the water tray 5 of the carbon dioxide incubator, humidification is performed by hanging absorbent paper or wet and dry towels 4 on the crossbeam of the stainless steel bracket 1. The bottom of the paper towel contacts the water surface 7, absorbs water, and evaporates the water into the air. Since the evaporation area of water is greatly increased, the humidity in the incubator can be effectively increased. After the experimenter opens and closes the door, the humidity recovery speed is accelerated, and the evaporation of water in the culture solution is reduced, thereby ensuring the normal growth of cells.
[0021] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
