VWR Centrifuge Tube 2 ml Free Standing Screw Cap Sealed 1000 Tubes

VWR 16466-058 Centrifuge Tube – 2.0 mL, Free-Standing, Screw Cap

The VWR 16466-058 is a premium 2.0 mL microcentrifuge tube designed for secure sample containment, long-term cryogenic storage, and high-speed processing. Constructed from high-clarity, medical-grade polypropylene, these tubes feature a free-standing, skirted base that allows them to remain upright on the benchtop without the need for a rack. Equipped with a secure screw cap and an integrated O-ring seal, the 16466-058 provides a leak-proof barrier against evaporation and contamination. These tubes are engineered to withstand extreme thermal stresses, making them suitable for everything from boiling water baths to vapor-phase liquid nitrogen storage.

Technical Performance and Design

• Free-Standing Skirted Base: The stable, flat-bottom exterior allows the tube to stand independently, facilitating easier one-handed additions and reducing the risk of benchtop spills.

• O-Ring Screw Cap Seal: Features a precision-fitted ethylene propylene (EP) O-ring within the cap to ensure a pressurized, airtight seal that prevents leakage during high-speed centrifugation or vortexing.

• High-Centrifugation Stability: Rated for high G-forces, the robust wall thickness prevents tube failure and ensures sample integrity even during intensive pelleting protocols.

• Ultra-Low Temperature Resilience: Designed for use in temperatures ranging from -196°C to +121°C, providing a versatile solution for both cryogenic freezing and autoclaving.
