Rasayan Tube Culture Flat Bottom With Screw Cap and rubber/ PTFE Liner

The Rasayan Tube Culture with Flat Bottom, Screw Cap, and Rubber/PTFE Liner is a laboratory vessel specifically designed for culturing microorganisms or conducting experiments requiring airtight containment. Here's a breakdown of its features: Tube Design: The tube has a flat bottom, allowing it to stand steadily on a laboratory bench or within a rack. This design ensures stability during handling and prevents accidental spills. Screw Cap: The tube comes with a screw cap, which provides a secure closure. Screw caps are easy to open and close, facilitating repeated access to the contents of the tube while maintaining a tight seal to prevent contamination. Rubber/PTFE Liner: The screw cap is equipped with a liner made of either rubber or PTFE (polytetrafluoroethylene). These liners serve as an additional barrier to ensure an airtight seal, preventing the entry of contaminants and maintaining the sterility of the contents inside the tube. Rubber liners are commonly used for general laboratory applications, while PTFE liners offer enhanced chemical resistance and are suitable for more demanding environments.
