VWR® Ultra High Performance Centrifuge Tubes

Every tube is molded from an optically clear, premium medical-grade resin that maximizes sample visibility while remaining completely non-cytotoxic to delicate cell lines. To support sensitive molecular biology and biochemistry protocols, these tubes are certified RNase-, DNase-, and endotoxin-free. The versatile material profile is fully freezable down to –80°C for deep cryogenic archiving and autoclavable up to 121°C for sterile reusability.

Key Functional Benefits:

• Advanced Leak Prevention: Flat Caps incorporate a molded-in elastomeric sealing ring to maintain a hermetic seal during vigorous vortexing and extended rocker incubations
• Elite Molecular Workflow Integrity: Certified free of RNase, DNase, and endotoxins (pyrogens) to eliminate experimental artifact vectors and protect sensitive DNA/RNA targets from degradation
• High-Visibility Measurement Matrix: Adorned with sharp, bold black graduations printed in precise ±2% intervals, paired with a large frosted writing panel for rapid, smudge-free sample identification
• Sterilized via Irradiation: Gamma irradiated to guarantee strict sterility parameters, allowing immediate integration into cleanrooms and sterile cell culture hoods

IMPORTANT! Autoclaving Safety Requirement: When autoclaving these centrifuge tubes for sterile reuse at 121°C, caps must be loosely attached to the tube threads. Securing the caps tightly before autoclaving will create a thermal vacuum during the cooling cycle, causing structural tube deformation or cracking.

Ordering Information: Tubes are available packaged in bags or earth-friendly, recyclable racks. Tubes with separate caps are supplied in separate bags of 500 tubes and 500 caps.
