How It Works
Cryogenic storage accessories function by providing structured organization within liquid nitrogen dewars while maintaining thermal contact with the cryogenic medium. The 304 stainless steel construction exhibits minimal thermal expansion at liquid nitrogen temperatures, ensuring dimensional stability and consistent sample positioning during freeze-thaw cycles.
Round canisters accommodate cylindrical sample containers in vertical arrays, maximizing storage density while enabling individual sample retrieval. Square canisters provide horizontal shelf configurations for larger sample volumes or flat-bottom containers. Both designs facilitate rapid thermal equilibration with the liquid nitrogen environment while protecting samples from cross-contamination through physical separation.
The storage system operates through direct immersion in liquid nitrogen, where samples achieve temperatures of -196°C within minutes of insertion. This rapid cooling rate minimizes ice crystal formation and cellular damage, particularly critical for viable cell preservation and enzymatic activity maintenance.

The system provides 304 stainless steel construction in both round and square configurations for comprehensive cryogenic sample organization. The dual canister design accommodates diverse sample types while maintaining material consistency throughout the storage system.
Practical Tips
Pre-cool canisters gradually by partial immersion before full deployment to prevent thermal shock.
Why: Rapid temperature changes can cause material stress and potential structural damage.
Use appropriate cryogenic PPE including insulated gloves and face protection during canister handling.
Why: Direct contact with liquid nitrogen temperatures can cause severe frostbite injury.
Inspect canister surfaces regularly for signs of corrosion or mechanical damage from handling.
Why: Early detection prevents contamination issues and maintains storage integrity.
Maintain detailed sample position maps and implement standardized labeling systems.
Why: Organized documentation prevents sample mix-ups and enables efficient retrieval protocols.
Monitor liquid nitrogen levels regularly and establish refill schedules based on evaporation rates.
Why: Consistent temperature maintenance requires adequate liquid nitrogen coverage above sample level.
If samples show signs of temperature excursion, verify canister positioning and liquid nitrogen contact.
Why: Proper immersion is critical for maintaining cryogenic temperatures throughout the storage system.

Compliance
What is the maximum sample capacity for each canister type?
Sample capacity depends on container dimensions and configuration. Consult product datasheet for specific capacity specifications and dimensional compatibility charts.
How do I prevent cross-contamination between stored samples?
Use appropriate sample container sealing, maintain adequate spacing between containers, and implement sterile handling procedures during sample insertion and retrieval.
What maintenance is required for stainless steel canisters?
Regular cleaning with laboratory detergents, periodic inspection for structural integrity, and documentation of thermal cycling history for quality assurance protocols.
Can these accessories be used with different dewar manufacturers?
The system is designed for standard liquid nitrogen dewars. Verify dimensional compatibility with your specific dewar model before implementation.
How quickly do samples reach storage temperature?
Thermal equilibration time depends on sample volume and container material. Small samples typically reach liquid nitrogen temperature within minutes of immersion.
What documentation is needed for regulatory compliance?
Maintain storage temperature logs, sample inventory records, and equipment qualification documentation as required by your laboratory's quality management system.
