ScrewSeal™ Screw Cap Microcentrifuge Tubes
ScrewSeal™ Screw Cap Microcentrifuge Tubes are high-performance, sterile microtubes designed for secure sample handling across a wide range of laboratory applications. Available in multiple sizes, cap styles, and graduation options, including light-blocking amber tubes for light-sensitive samples, these tubes deliver exceptional versatility and protection.
Manufactured from ultra-clear polypropylene, ScrewSeal™ tubes provide excellent visibility for accurate sample inspection. Each tube includes an assembled screw cap with a silicone O-ring, ensuring a dependable leak-proof seal from –90°C to +121°C. This makes them ideal for freezing, boiling, centrifugation, and long-term storage.
All ScrewSeal™ microtubes are sterile, RNase-free, DNase-free, and pyrogen-free, supporting use in sensitive molecular biology workflows. They are engineered to withstand centrifugation speeds up to 22,000 x g when used with appropriate rotors, cushions, and adapters.
