CryoKing Cardboard Lab Freezer Box — 81-Well
The CryoKing 81-well cardboard box emphasizes straightforward organization with included cardboard dividers and a secure lid. The outer white coating and durable cardboard construction support long-term use in cryogenic settings. It tolerates exposure to alcohols and mild organic solvents, providing a safe storage solution for many liquid nitrogen workflows.
This box is designed for vapor-phase liquid nitrogen storage, offering a temperature range from -196°C to 121°C. Its lightweight design aids handling in busy lab environments, while the dividers help scientists keep samples categorized by project, tube type, or experiment stage. The lid’s seal helps prevent sample contamination and evaporation during handling.
Who it’s for
Labs seeking a cost-effective, disposable-friendly 81-well system with simple organization and reliable cryo performance will find this model suitable for routine sample storage and quick access during experiments.
Notes
As with all cardboard-based cryoboxes, consider supplementary padding or shelving in ultra-cold storage racks to minimize handling damage and to ensure consistent labeling across batches.
CryoKing 2 Inch 81-Well Freezer Boxes — 5 Pcs
This five-pack of CryoKing 2 Inch height 81-well boxes emphasizes efficient organization with built-in cardboard dividers and a secure lid. The durable white cardboard construction offers resistance to alcohols and mild organic solvents, enhancing safe storage in lab environments where chemical exposure is possible.
Operating in a temperature window from -196°C to 121°C, these boxes are compatible with vapor-phase liquid nitrogen storage. They facilitate rapid sample retrieval while maintaining separation between tubes for minimized cross-contamination. The pack format supports larger projects and shared lab usage, enabling crew-wide access without sacrificing organization.
Considerations
For labs with frequent sample turnover, this five-pack provides consistent box geometry and lid mechanism across multiple units, simplifying inventory management and reducing mismatch risks when re-shelving boxes.
CryoKing 2 Inch Lab Freezer Boxes — Case of 100
This case-of-100 selection is designed for high-volume laboratories requiring consistent 81-well boxes for routine cryogenic storage. The durable cardboard design features a white outer coating and dividers for efficient sample separation. It is chemically resistant to alcohols and mild organic solvents, supporting safe handling in mixed chemical environments.
With a broad temperature tolerance of -196°C to 121°C, the CryoKing case supports vapor-phase liquid nitrogen workflows, maintaining sample integrity during transfers between storage and experiments. The stacking-friendly form factor helps maximize rack capacity in limited cold rooms, while the separate lid ensures secure closure between uses.
Application
Ideal for core facilities, core labs, or university departments where large numbers of microtubes require reliable, standardized storage across multiple projects and researchers, without sacrificing organization speed.
CryoKing Lab Freezer Box with Plastic Coating — 2 Inch
This CryoKing model combines a durable cardboard core with a waterproof plastic coating, enhancing resistance to moisture and certain solvents. The coated surface helps protect the box during cleaning and handling in lab environments and provides an extra shield for long-term storage of valuable samples.
Featuring 81 wells and an efficient divider system, the unit supports clear organization for quick access during experiments. Its low-temperature tolerance remains aligned with vapor-phase liquid nitrogen storage, spanning -196°C to 121°C. The lid’s secure seal prevents cross-contamination and sample loss during transport or routine reorganization.
Practical notes
Consider this model when moisture exposure or spill risk is a concern, as the plastic coating adds a protective layer without sacrificing the ease of labeling and categorization.
Scienfocus Lab Cryogenic Storage Box — 81-Well
The Scienfocus cryogenic storage box features a PC construction and an 81-well layout compatible with 0.5, 1.5, and 2.0 mL tubes. It is designed for ultra-low temperatures, capable of withstanding liquid nitrogen down to -200°C and handling mild organic solvents, expanding its versatile lab use beyond pure cryogenic storage.
A printed coordinate grid on the surface supports quick tube identification, minimizing handling time during experiments. The product includes a ventilation design with long, round holes that facilitate rapid inflow and outflow of liquid nitrogen, reducing pressure-related issues during cooling cycles.
Usage guidance
Use this box where fast identification and efficient LN2 transfer are priorities, and where a digital or semi-analog tracking system benefits workflow efficiency in busy labs.
Buying Guide: Key Purchase Considerations
- Storage temperature and compatibility: Ensure the box supports -196°C in vapor-phase LN2 storage and that materials tolerate alcohols and mild solvents common in the lab.
- Construction and durability: Cardboard cores with protective coatings work well for cost and handling, while plastic-coated options add moisture resistance for spills and humidity-prone areas.
- Organization features: Look for built-in dividers, clearly labeled coordinates, and secure lids to maintain sample separation and prevent cross-contamination.
- Capacity and batch needs: For large facilities, cases with 100 boxes or multi-pack options can streamline procurement and inventory control.
- Handling and ergonomics: Box weight, lid ease, and finger-access design affect daily handling in busy cryogenic rooms or during rapid sample sorting.
- Compatibility with tube sizes: Ensure the wells accommodate your common tube diameters (0.5–2.0 mL) to minimize transfers and re-packing.
- Storage footprint: Consider rack compatibility and stack height to maximize cold-room space without compromising accessibility or safety.
- Labeling and traceability: A coordinate grid or clear labeling helps ensure samples are traceable across projects and over time.
- Cost vs. longevity: Cardboard boxes offer affordability but may require more frequent replacement; coated or plasticized variants trade some cost for durability.
- Regulatory and safety considerations: Verify that storage boxes align with your institution’s biosafety and chemical handling policies, especially for mixed solvents and LN2 exposure.
