Description

Technical Field

[0001] The utility model relates to the technical field of experimental utensils, and particularly refers to a centrifuge tube with a breathable cover. Background Art

[0002] A centrifuge tube is a commonly used laboratory equipment, mainly used for centrifugation operations. It is generally made of plastic or glass. Plastic centrifuge tubes are light in weight, not easy to break, low in cost and have good chemical corrosion resistance. Common materials include polypropylene, polycarbonate, etc.; glass centrifuge tubes have high transparency and good chemical stability, which is convenient for observing samples. Centrifuge tubes are usually cylindrical, with different capacity specifications. The tube caps have types such as screw caps and flip caps, and some are equipped with gaskets.

[0003] The lids of ordinary centrifuge tubes are usually in a sealed state and lack air permeability. For culturing cell tissues and microorganisms, the traditional operation is to transfer the culture medium from the culture flask to the centrifuge tube for centrifugation. However, such a transfer process is prone to contamination risks. Therefore, ordinary centrifuge tubes are not suitable for culturing cell tissues and microorganisms. Currently, centrifuge tubes with a breathable function have been put into use, but the ventilation holes on the lids of such centrifuge tubes are always open. If ventilation is not required, another closed tube cap needs to be prepared, which is rather troublesome. Summary of the Utility Model

[0004] In order to solve the above various problems, the utility model proposes a centrifuge tube with a breathable cover that has a switchable breathable and closed function and is suitable for both culturing and centrifugation.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a centrifuge tube with a breathable cover, including a tube body and a tube cap. The tube body and the tube cap are threadedly connected. There is a circular protrusion on the tube cap. There are equally spaced and annularly distributed ventilation holes I on the circular protrusion. There are easily breakable short columns connected to the tube cap and located outside the circular protrusion. An upper cover is connected to the short columns. The inner wall of the upper cover and the outer circle of the circular protrusion are slidably arranged. The cover plate on the upper cover fits with the circular protrusion. There are ventilation holes II on the cover plate that are misaligned with the ventilation holes I.

[0006] Further, a breathable film is adhesively provided below the circular protrusion inside the tube cap. It can effectively prevent external dust, impurities, etc. from entering the centrifuge tube while ensuring ventilation, ensuring a pure environment for culturing cell tissues and microorganisms and avoiding contamination.

[0007] Further, a tear strip is connected to the edge below the breathable film. It is convenient to replace the breathable film when needed, with simple and convenient operation, improving the reusability and flexibility of the centrifuge tube.

[0008] Further, an embedded groove is provided on the circumference of the circular protrusion, and an arc-shaped sliding bar that is slidably arranged with the embedded groove is connected to the inner side of the upper cover. This makes the opening and closing of the upper cover smoother and more stable, and can accurately control the coincidence and dislocation of the first ventilation hole and the second ventilation hole, improving the convenience and reliability of using the centrifuge tube.

[0009] Further, equidistant anti-slip grooves are integrally formed on the circumference of the tube cap. When operating the tube cap for screwing and other actions, the friction can be increased to prevent hand slipping, making the operation safer, more stable and efficient.

[0010] Further, a capacity scale is provided on the tube body. This facilitates the user to accurately master the amount of sample or culture medium added to the centrifuge tube, which is beneficial to the standardization and accuracy of the experiment.

[0011] Further, the number and spacing of the first ventilation hole and the second ventilation hole are the same, and a blocking block is provided in the embedded groove. When the arc-shaped sliding bar touches the blocking block, the first ventilation hole and the second ventilation hole coincide. When the arc-shaped sliding bar touches the blocking block, the first ventilation hole and the second ventilation hole coincide, which can accurately control the ventilation state and meet the ventilation degree requirements in different experimental stages.

[0012] Further, the short column can be broken off by screwing the upper cover. When complete sealing is required, just leave it unchanged to ensure the sealing property. When ventilation is needed, just break it off.

[0013] The advantages of the present utility model compared with the prior art are as follows:

[0014] It has a switchable ventilation and sealing function: The switchable ventilation and sealing function makes the centrifuge tube extremely convenient to use during the process. When conducting a cell culture experiment, if a ventilation state is required, just screw the upper cover to make the first ventilation hole and the second ventilation hole coincide, and good gas exchange can be achieved, providing a suitable environment for cell growth. When a sealing state is required, just leave the upper cover unchanged to ensure the sealing property and prevent external impurities from entering. When conducting a centrifugation operation, there is no need to replace the container either. The good sealing property can be directly utilized for high-speed centrifugation, greatly improving the efficiency of the experimental operation, reducing the operation steps and time costs.

[0015] Dual-purpose for culturing and centrifuging: This centrifuge tube has dual functions of culturing and centrifuging, and the switchable ventilation and sealing function provides a strong guarantee for its functional diversity. For scientific research personnel, there is no need to prepare various containers with different functions. One centrifuge tube can meet the requirements of different experimental stages. During the culturing stage, the ventilation function ensures the normal growth of cell tissues and microorganisms; during the centrifugation stage, the sealing function guarantees the safety of the sample and the centrifugation effect. This functional diversity not only saves experimental space and costs, but also improves the coherence and integrity of the experiment. BRIEF DESCRIPTION OF THE DRAWINGS

A tear strip 9 is connected to the lower edge of the breathable film 8. It is convenient to replace the breathable film 8 when needed, the operation is simple and convenient, and the reusability and flexibility of the centrifuge tube are improved.

The cover plate on the upper cover 6 fits with the upper surface of the circular protrusion 3. There is a second ventilation hole 7 on the cover plate that is misaligned with the first ventilation hole 4. The short column 5 can be broken by twisting the upper cover 6. When complete sealing is required, just leave it unchanged to ensure the sealing property. When ventilation is needed, just break it off.

[0026] Combined with the attached Figure 1 and the attached Figure 4 , there is an embedded groove 10 around the circumference of the circular protrusion 3, and an arc-shaped sliding strip that is slidably arranged with the embedded groove 10 is connected to the inner side of the upper cover 6. This makes the opening and closing of the upper cover 6 smoother and more stable, and can accurately control the coincidence and misalignment of the first ventilation hole 4 and the second ventilation hole 7, improving the convenience and reliability of using the centrifuge tube.
