Cardboard Freezing Boxes for 15 mL & 50 mL Centrifuge Tubes — 16- and 49-Place, White, Sold Each
The Globe Scientific Cardboard Freezing Box organizes conical centrifuge tubes for cold storage in walk-in freezers, chest freezers, and liquid-nitrogen vapor racks. White board with a divider grid keeps each tube isolated and upright, supporting biobanking, long-term sample archiving, and reagent stock management.

Chemical Resistance
The coated board resists incidental contact; tubes provide the primary chemical barrier. Compatibility below reflects exposure to box exterior, not immersion.
| Reagent Class | Compatibility |
| Aqueous buffers | Good (coated surface resists condensation) |
| Dilute acids | Limited — wipe spills promptly |
| Dilute bases | Limited — wipe spills promptly |
| Alcohols | Fair — brief contact only |
| Acetonitrile | Poor — avoid direct exposure |
| Aromatic solvents | Poor — not recommended |
| Chlorinated solvents | Poor — not recommended |

Frequently Asked Questions
How many tubes does each freezing box hold?
The 15 mL box (SKU 3098-1) uses a 7x7 grid for 49 tubes, while the 50 mL box (SKU 3099-1) uses a 4x4 grid for 16 tubes.
What temperatures can these cardboard boxes withstand?
Coated cardboard freezing boxes are rated for typical lab freezer ranges down to −80°C and vapor-phase liquid-nitrogen storage. Repeated frost cycles can soften uncoated board, so keep boxes dry between retrievals.
Are the boxes sold individually or in a case?
Pricing shown is per each box, including the divider grid and lid. Bulk case quantities are available through tiered institutional pricing.
Will the box fit standard conical centrifuge tubes?
Yes. The 7x7 box is dimensioned for standard 15 mL conical tubes and the 4x4 box for standard 50 mL conical tubes. Verify tube outer diameter against grid cell size for non-standard brands.
