Description

A reagent bottle cap protective sleeve

technical field

The utility model relates to an anti-microbial pollution protection device, in particular to a reagent bottle cap protective sleeve.

Background technique

During the storage of bottled reagents, many experiments require that the reagents should not be contaminated by microorganisms, such as various media and buffers required for cell culture. However, the experimental process involving bottled reagents may cause contamination of the reagents, especially during the process of opening and closing the bottle caps, microorganisms around the bottle caps may enter the bottle and cause contamination.

At present, there are two main designs of reagent bottle caps. One is to make a rubber sealing ring on the inner upper end of the bottle cap, which can isolate external microorganisms to a certain extent; the other is to add rubber rings to the inner upper end of the bottle cap and the mouth of the reagent bottle. , its effect of isolating pollution is better than the first one. However, only relying on these two rubber sealing rings cannot fully play the role of preventing external microorganisms from contaminating reagents in actual operation.

In the actual operation of the experiment, in order to avoid the contamination of the reagent by microorganisms, an alcohol lamp is often used to burn the mouth of the reagent bottle and the bottle cap during the process of opening or closing the bottle cap, and then wrap the Parafilm M sealing film to seal the lower edge of the bottle cap after tightening gap. This kind of film is corrosion-resistant, has good flexibility and good ductility, and can effectively block the intrusion of external microorganisms into the inside of the bottle cap, and reduce the contamination of reagents during storage and use. However, the protection method of Parafilm M sealing film has obvious disadvantages in some cases: Parafilm M sealing film is a disposable consumable and cannot be reused, and the cost is high; when the reagent bottle is placed in a 37°C water bath, Parafilm M sealing Membrane properties can change, ductility decreases, viscosity increases, and the ability to seal and isolate is reduced. At this time, the sewage in the water bath may gather at the bottle wall and bottle mouth, invade the inside of the bottle cap, and greatly increase the possibility of reagent contamination. Increase; the viscosity of Parafilm M film will change with temperature and time, and when it is torn off from the bottle mouth, it will stick to the bottle cap and it is difficult to tear it off.

Preferably, a gasket is provided at the lower part of the inner wall of the jacket. The lower edge of the sealing pad is flush with the lower edge of the body, preventing sewage and microorganisms from polluting the bottom of the bottle cap.

In the above technical solution, in order to protect the bottle cap and isolate it from the outside world, the sleeve body is made of PP polypropylene plastic.

Due to the use of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. The protective cover of the reagent bottle cap disclosed in the utility model is a part that isolates the bottle cap from the outside world, and the lower edge is at the same height as the annular belt outside the neck of the reagent bottle. When in use, the folded part is adjusted so that the cover body can be opened and closed at will To the desired angle, it can adapt to different bottle cap sizes.

2. The reagent bottle cap protection sleeve disclosed by the utility model is equipped with a sealing gasket. When in use, the sleeve body is pulled down to the bottom of the ring belt, so that the neck of the bottle and the bottle cap inside the ring belt are all wrapped, and through the inner side of the lower edge of the sleeve body The gasket prevents sewage from entering the gap between the bottle cap and the bottle neck.

3. The protective sleeve for the reagent bottle cap disclosed in the utility model is provided with a buckle structure, through which the sleeve body is closed and locked, and is firmly fixed to the bottle neck of the reagent bottle. At the same time, the opening is provided with a sealing strip, and the two side edges of the opening are tightly fitted by the lateral force generated by the buckle structure, so that the side wall of the sleeve is tightly closed.
