Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, and in particular to a culture flask for culturing cells. Background Technology

[0002] After cells have grown in cell culture flasks for a certain period of time, they need to be transferred, which is called cell passage. During cell growth, cells grow on the walls of the culture flasks, and the process of transferring and removing them is done by pipetting.

[0003] In the prior art, when the pipette tip is placed into the cell culture flask, the narrow opening of the existing culture flask restricts the entry and exit of the pipette tip. During the pipetting process, it is impossible to reach all corners inside the culture flask. Furthermore, the bottom of the culture flask is too flat or has dead corners, which affects the operating range of the pipette tip, preventing some cells from being effectively pipetted down, thus causing waste. Utility Model Content

[0004] This invention mainly provides a culture flask for culturing cells that facilitates all-round blowing and reduces cell waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a culture flask for culturing cells, comprising: a flask base, a base plate fixedly connected to the top of the inner surface of the flask base, an inclined plate fixedly connected to the left surface of the base plate, a flask tube fixedly connected to the left surface of the flask base, a chamfered opening on the left end face of the flask tube, a flask cap threadedly connected to the outer surface of the flask tube, and a vent hole provided on the end face of the flask cap.

[0006] Preferably, the outer surface of the inclined plate is fixedly connected to the inner surface of the bottle holder, and the angle between the inclined plate and the base plate is 150 degrees. By setting the angle between the inclined plate and the base plate, the inclined plate can have a longer slope wall, thereby increasing the operating range of tools such as aspirators or cell scrapers inside the bottle. When the tool slides along the inclined plate, it can more easily reach the cells on the base plate surface and the inner wall of the bottle holder, achieving blow-drying without dead angles.

[0007] Preferably, the outer surface of the bottle cap is provided with anti-slip texture. The anti-slip texture increases the friction between the bottle cap and the hand, making it less likely for the bottle cap to slip during operation, which helps to improve the safety and stability of the operation.

[0008] Preferably, the diameter of the right end face of the bottle tube is larger than the diameter of the left surface of the bottle holder. By increasing the width of the bottle tube, it is easier for external tools to enter the interior and to better cover the entire inner wall.

[0009] Preferably, the front surface of the bottle holder is provided with a scale. The scale can help the operator to more accurately control the amount of liquid during the blowing process and avoid cell waste.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the design of the bottle tube and the chamfer makes it easier for external tools to enter the interior and better cover the entire inner wall, reducing dead angles of the suction gun at the bottle tube and improving blowing efficiency. The angle between the inclined plate and the base plate makes the inclined plate longer, thereby increasing the operating range of the tool inside the bottle. Therefore, when the tool slides along the inclined plate, it can more easily reach the cells on the base plate surface and the inner wall of the bottle holder, achieving blowing without dead angles.

[0012] 2. In this invention, the setting of the scale can help the operator to more accurately control the amount of liquid during the blowing process and avoid cell waste. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4This utility model provides a technical solution: a culture flask for culturing cells, comprising: a flask base 1, a base plate 6 fixedly connected to the top of the inner surface of the flask base 1, an inclined plate 7 fixedly connected to the left surface of the base plate 6, a flask tube 2 fixedly connected to the left surface of the flask base 1, a chamfer 8 opened on the left end face of the flask tube 2, a flask cap 3 threadedly connected to the outer surface of the flask tube 2, and a vent hole 4 provided on the end face of the flask cap 3.

[0021] like Figures 1-4 The outer surface of the inclined plate 7 is fixedly connected to the inner surface of the bottle holder 1. The angle between the inclined plate 7 and the base plate 6 is 150 degrees. By setting the angle between the inclined plate 7 and the base plate 6, the inclined plate 7 can have a longer slope wall, thereby increasing the operating range of tools such as aspirators or cell scrapers inside the bottle. When the tool slides along the inclined plate 7, it can more easily reach the cells on the surface of the base plate 6 and the inner wall of the bottle holder 1, achieving blow-drying without dead angles.

[0022] like Figures 1-4 The outer surface of the bottle cap 3 is provided with anti-slip texture. The anti-slip texture increases the friction between the bottle cap 3 and the hand, making it less likely for the bottle cap 3 to slip during operation, which helps to improve the safety and stability of operation.

[0023] like Figures 1-4 The diameter of the right end face of the bottle tube 2 is larger than the diameter of the left surface of the bottle holder 1. By increasing the width of the bottle tube 2, it is easier for external tools to enter the interior and to better cover the entire inner wall.

[0024] like Figures 1-4 The front surface of the bottle holder 1 is provided with a scale 5. The scale 5 can help the operator to control the amount of liquid during the blowing process more accurately and avoid cell waste.

[0025] Working principle: During use, the bottle cap 3 has a filter membrane inside, which, together with the vent 4, ensures unobstructed gas exchange during cell culture. When it is necessary to blow air into the inside, the anti-slip texture stably separates the bottle cap 3 from the bottle tube 2. Then, the suction gun is inserted into the inside along the bottle tube 2. During insertion, the wider bottle tube 2 makes it easier for external tools to enter the inside and better cover the entire inner wall. The chamfer 8 helps to reduce dead angles for the suction gun at the bottle tube 2, improving blowing efficiency. Furthermore, the angle between the inclined plate 7 and the base plate 6, along with... Figure 1 As shown, the length of the inclined plate 7 is slightly shorter than the length of the base plate 6, which allows the inclined plate 7 to have a longer slope, thereby increasing the operating range of tools such as aspirators or cell scrapers inside the bottle. Therefore, when the tool slides along the inclined plate 7, it can more easily reach the cells on the surface of the base plate 6 and the inner wall of the bottle holder 1, achieving pipetting without dead angles. The scale 5 can help the operator to more accurately control the amount of liquid during the pipetting process and avoid cell waste.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
