Description

Fixing device for fixing glassware and stopper

technical field

The utility model relates to the technical field of laboratory appliances, in particular to a fixing device for fixing glassware and stoppers.

Background technique

In chemical, biological and other experiments, glassware is often used, and stoppers with specific structure and fit are often used together with glassware. There are usually two types of stoppers, bottle stoppers and tube stoppers, such as volumetric bottle stoppers and colorimetric tube stoppers. Although there are certain differences in its structure, the principle is to polish the joint between the mouth of the container and the stopper so that the two can match, so as to achieve the effect of blocking the solution. The technical requirement is to meet a high degree of matching in order to achieve the sealing effect, so the compatibility between the glassware and the stopper used is very important. The glassware in the experiment usually encounters non-working conditions such as use, cleaning, disinfection, storage, etc. During these processes, the stopper is usually separated from the glassware, and during the experiment, it is usually desirable to avoid the stopper from being separated from the glassware. Separation, so as to avoid leakage and pollution to ensure the accuracy of the experiment.

During the experiment, the colorimetric tube is usually used as a container for digestion samples. In order to avoid the influence of external substances on the substances in the tube, stopper digestion is usually used during the digestion process. Due to the process of internal liquid heating and expansion, the stopper will splash. In order to prevent this phenomenon, the colorimetric tube stopper is usually wrapped before digestion. The traditional method is to wrap it with cotton cloth and tie it with a string. The process is time-consuming and complicated. , It is also inconvenient to disassemble; when using a volumetric flask, it is often necessary to use a cork to block the mouth of the bottle for the preparation and mixing of the solution, etc. Volumetric flask and stopper to ensure matching. The cord is not easy to disassemble, and the rubber band is easy to be oxidized and corroded; when storing glassware, they need to be stacked to save space. If the stopper and the main body of the glassware are not fixed well, it is easy to smash or smash the lower vessel after the stopper slips If it is cracked, you must be extra careful when handling it, which will make the operation more difficult. The traditional fixing methods of the above two typical pipe stoppers and bottle stoppers in the experiment have disadvantages. If they are not fixed, there is a risk of breaking and breaking. It is urgent to improve the disadvantages of this traditional method of fixing pipe stoppers and bottle stoppers.
