Why selected: A pack of six boxes provides flexibility for expanding sample sets and creating organized sections by project or assay type.
Limitations: Non-PVC materials may be less forgiving in extreme handling conditions; confirm compatibility with your LN2 workflow.
Buying Guide
What material matters most?
Polypropylene boxes are common for cryogenic use due to good chemical resistance, temperature tolerance, and reusability. Cardboard options offer cost savings and lightness but may be less durable over time. Consider your environment, frequency of use, and disposal policies when choosing material.
How many wells do you need?
Assess your typical sample size per box. If you regularly store 0.5–2 ml tubes, a 100-well layout provides ample capacity per box. For large-scale projects, multiple boxes with color-coding or numbering can streamline workflow.
Is color-coding worth it?
Color-coded boxes help prevent mix-ups and speed retrieval in busy labs. If your team relies on quick visual checks, choose boxes with multiple colors or transparent lids that allow easy scanning.
What about temperature tolerance?
Most boxes list a usable range from -196°C to 121°C for vapor-phase LN2 storage. If you plan to use liquid nitrogen directly, verify the box’s compatibility with your LN2 handling method and ensure lids seal reliably under temperature changes.
Storage and accessibility considerations
Look for hinged latches for secure closure, clear or transparent lids for content visibility, and smooth edges to prevent microtube snagging. Internal dividers or modular designs can help maintain organization across categories or projects.
Durability and long-term use
For repeated freezing and thawing, select boxes made from sturdy plastic with minimal warping risk. The ability to withstand temperature cycling without cracking or losing lid integrity is important for long-term labs.
FAQ
- What size tubes do these boxes accommodate? Most boxes support 0.5, 1.5, and 2 ml microcentrifuge tubes, but always verify inner lattice diameter (about 13 mm in these options).
- Are these boxes safe for LN2 vapor phase storage? Yes, several options specify a temperature range including -196°C to 121°C, suitable for LN2 vapor-phase use.
- Can I mix cardboard and plastic boxes in the same storage system? It is possible, but for best stability and retrieval, group by material type and ensure consistent labeling and handling.
- Do these boxes come with lids? Yes, all listed options include hinged lids or secure snap closures to protect samples.
- How important is lid transparency? Transparent lids enable quick checks without opening, reducing sample exposure and cooling loss.
- What is the best option for color-coding? Boxes with multiple color options or colored lids help distinguish sample types and projects at a glance.
