Screw Tubes
Screw-cap tubes are designed to withstand ultra-low temperature storage without deformation, ensuring reliable performance even in deep-freeze conditions. The secure, tight-sealing closure minimizes the risk of contamination, while the multi-colored caps allow for easy and efficient sample identification.
Key features:
- Medical-grade materials – tube made of polypropylene (PP), cap made of high-density polyethylene (HDPE), and silicone O-ring; all components are free of heavy metals
- High centrifugation resistance – maximum RCF up to 20,000 × g, suitable for demanding separation protocols
- Wide temperature compatibility – stable from −80 °C to 121 °C; autoclavable
- High material purity – free of detectable DNase, RNase, and human DNA; non-pyrogenic
- Sterile execution – sterilized by irradiation and certified non-pyrogenic
- Color-coded caps for easy identification – available in natural, red, blue, yellow, and green
