1. What Are Screw Cap Culture Tubes?

Culture tubes are cylindrical containers used in scientific research and medical laboratories to grow, store, and transport microorganisms, cells, and tissues for research and experimentation.

2. What Are the Differences Between Polypropylene (PP) and Polystyrene (PS) Materials When Selecting Screw Cap Culture Tubes?

Polypropylene (PP) is a thermoplastic polymer that demonstrates high thermal stability, making it an excellent choice for applications that require high-temperature sterilization. It also provides exceptional durability and chemical stability, making it ideal for storing corrosive or erosive samples. In addition, it exhibits excellent resistance to chemicals, acids and alkalis, further highlighting its suitability for these types of applications.

On the other hand, polystyrene (PS) is a synthetic polymer that acts as a good insulator while also having superior optical clarity. Its transparency makes it an excellent choice for applications that require sample visibility, such as visualization of sample growth.

In summary, the decision between PP and PS culture tubes is based on the specific requirements of the application. PP is well suited for applications requiring high-temperature sterilization and chemical resistance, whereas PS culture tubes are preferred due to their optical clarity.
