Disposable swabs are mainly used for the collection of microorganisms and clinical test specimens, and are suitable for collecting and using in hospitals or laboratories for virus detection or research. They undergo biological sample testing in the natural cavities of humans or animals, such as the throat, nose, mouth, vagina, and other parts. In addition, disposable swabs can also be used for disease detection in the human oral and nasal cavities. Sampling swabs need to be used for the collection of oral epidermal cells and nasal virus samples, and the cells or samples should be stored in collection tubes before being transferred to the laboratory for testing.

Vacuum blood collection vessels are usually composed of a tube and a skull. Pipes are generally made of PET (polyethylene terephthalate) or glass tubes, with or without additives or additives attached to the inner walls of the tubes.

Plastic centrifuge tubes are widely used in molecular biology, biochemical experiments, and the pharmaceutical industry. The main materials include polypropylene (PP) and polyethylene (PE), which have good corrosion resistance, high temperature resistance, and pressure resistance. Suitable for low-speed centrifugation and low-temperature centrifugation, but not suitable for high-speed centrifugation and high-temperature conditions.
