These polypropylene sample tube and caps are designed for storage and transport of biological materials.
- Tubes feature internal threads
- Withstand temperatures from –196 to +121 °C

High-quality screw cap sample tubes are manufactured of translucent autoclavable polypropylene. Caps are supplied with a silicone washer to ensure a positive leakproof seal at all temperatures. A 1.25 turn of the cap is sufficient to seal the vial.
Since both closures and tubes are manufactured of the same material, they have the same coefficient of expansion to guarantee an equally secure seal both at room or at low temperatures. Round bottom tubes only can be centrifuged up to 14000×g.
Cap features a long skirt and a superfast thread design allowing it to be removed or screwed on with a single turn. Caps are supplied with a silicone washer to ensure a positive leakproof seal at all temperatures.
