Simport Sample Tubes with External Threads and Closures

Designed for the storage and transportation of biological material. Manufactured from non-toxic polypropylene, the tube provides strength and clarity and exhibits some unique design features. The vial has external threads, providing a smooth and uniform inner surface, thus reducing the risk of contamination. Tubes can be autoclaved (121°C) in upright position with caps loosened. Round bottom tubes can be centrifuged up to 17,000 x g. Polypropylene caps (not included) are available with or without silicone washer (washer provides a positive leakproof seal). Opens with a single turn. Tubes and caps are non-sterile.
