Non-Graduated Polypropylene Sample Tubes

Introducing our Non-Graduated Polypropylene Sample Tubes, specifically designed for the secure storage and transportation of biological materials. Crafted from high-quality non-toxic polypropylene, these tubes exhibit exceptional strength and clarity, ensuring reliable handling of your samples. The external threads of the vials provide a smooth and uniform inner surface, significantly minimizing the risk of contamination.

Our polypropylene screw caps complement the tubes perfectly, sharing the same coefficient of expansion, which guarantees a consistent fit and leakproof seal even under fluctuating temperatures. Featuring a long skirt and a super-fast thread design, these caps can be easily removed or securely sealed with just a single turn. Caps are available with or without a silicone o-ring and come in a variety of colors to meet your specific requirements.
