Fisherbrand Centrifuge Tube 1.5 ml Screw Cap with O-Ring 500 Tubes

Description

Fisherbrand 02-681-372 Screw-Cap Microcentrifuge Tube – 1.5 mL, O-Ring, Polypropylene

The Fisherbrand 02-681-372 is a premium 1.5 mL microcentrifuge tube designed for applications that require a higher level of security than a standard snap-cap tube can provide. Manufactured from high-purity, medical-grade polypropylene, these tubes feature a screw-cap closure equipped with an ethylene polypropylene O-ring. This design ensures a dependable, leak-proof seal that prevents sample evaporation and protects against leakage during high-speed centrifugation or extreme temperature changes. With a conical bottom and a self-standing base (skirted), these tubes are optimized for both manual handling and automated workflows, providing a robust solution for sample preparation, transport, and long-term cryogenic storage.

Technical Performance and Design

• O-Ring Seal Integrity: The integrated O-ring provides a mechanical seal that is significantly more secure than a friction-fit snap cap, making it ideal for boiling, vapor-phase LN2 storage, and the handling of infectious agents.

• Self-Standing (Skirted) Base: The tube features a skirted bottom that allows it to stand upright on a lab bench without a rack, facilitating easier one-handed opening and closing during high-throughput processing.

• High Centrifugation Stability: Engineered to withstand RCF (Relative Centrifugal Force) up to 18,000 x g, ensuring the tube remains intact and the seal remains secure under intense gravitational pressure.

• Optimized Material Purity: Constructed from non-cytotoxic, USP Class VI polypropylene, these tubes offer low-binding properties to ensure maximum recovery of proteins and nucleic acids.

Key Benefits & Applications

• Cryogenic Storage: The screw-cap and O-ring combination is the preferred format for banking cells or genomic material in ultra-low temperature freezers.

• Transport of Hazardous Samples: Meets IATA requirements for primary pressure receptacles, making these tubes suitable for the secure shipping of biological or chemical specimens.

• Proteomics & Genomics: Low-retention properties and high chemical resistance make these tubes suitable for protein purification, DNA extraction, and sensitive analytical chemistry.

• Boiling & Incubation: Unlike snap-caps which may pop open when heated, the screw-cap ensures sample containment during high-temperature incubation or water bath applications.
