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

The Rasayan Tube Culture with Flat Bottom, Screw Cap, and Amber-colored Rubber/PTFE Liner serves a similar purpose to the clear version but provides additional protection against light-sensitive samples. Here's a detailed breakdown: Tube Design: The tube features a flat bottom design, allowing it to stand steadily on laboratory surfaces or within racks. This design ensures stability during handling and prevents accidental spills. Screw Cap: Equipped with a screw cap, the tube offers a secure closure mechanism. These caps are designed for easy opening and closing, facilitating repeated access to the tube's contents while maintaining a tight seal to prevent contamination. Amber Color: The amber color of the tube serves as a light shield, protecting light-sensitive samples from degradation caused by exposure to UV or visible light. This feature is particularly crucial for samples such as light-sensitive chemicals or certain biological materials that can degrade when exposed to light. Rubber/PTFE Liner: The screw cap comes 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.
