Sterile Cryotube with Internal Screw Cap

Manufactured in FDA-approved medical-grade polypropylene. Maximises storage density in 10x10 boxes. Designed for reliable performance under cryogenic conditions.

Key Features

• Material: FDA-approved medical-grade polypropylene. Cap and tube share the same coefficient of thermal expansion.
• Temperature range: -196 °C to 120 °C
• Closure: Internal thread; half-turn, one-hand operation. Leak-proof seal.
• Base: Star-foot design—compatible with standard workstations.
• Profile: Optimised for 10x10 boxes. 23% increase in storage capacity versus standard cryotubes.

Sterility and Certifications

Sterilised to ISO 11137-2:2013 with a SAL of 10⁻⁶. RNase- and DNase-free. Produced in a cleanroom certified to ISO 9001, ISO 14001 and ISO 13485. Autoclavable.

Applications

Biological sample storage in liquid nitrogen and freeze-thaw cycling. Suitable for sample banks, biobanks, molecular biology laboratories and research centres.

Practical Advantages

The half-turn closure reduces hand fatigue during high-throughput sample processing. Drop-in compatibility with standard 10x10 boxes means no changes to existing storage infrastructure. Matched thermal expansion between cap and tube maintains a leak-free seal across the full temperature range.
