In biological experiments, it is often used as a container for microbial cultivation for the activation or other cultivation of microorganisms. Whether it is a chemical experiment or a biological experiment, test tube stoppers are sometimes used to create a relatively airtight space for the test tube. Especially in microbial culture, it is necessary to add a test tube plug to the test tube mouth, which can not only filter the air, but also prevent the contamination of bacteria, and slow down the evaporation of medium water. At present, the existing test tube plugs are basically self-made cotton plugs or commercially available test tubes. Plugs, self-made cotton plugs are the best for ventilation, but they are easily deformed and out of shape. They need to be replaced after several uses. They always need to be made, which is more troublesome and damages the material faster. Although the commercially available test tube plugs have a long service life, they have various specifications. , but there is a large difference between various specifications and cannot be used universally. When using in the laboratory, it is necessary to purchase test tube stoppers of all specifications, including test tube stoppers of uncommon specifications, which will increase the cost of consumables. The utility model provides a test tube suitable for various sizes. Test tube plugs, test tube plugs are suitable for a variety of test tubes of different sizes, reducing the consumption of consumables, saving costs, avoiding idle laboratory consumables, and test tubes of various sizes can be used in common, which brings convenience to experiments and is easy to promote.
