Polypropylene Film Cryogenic Freezer Box - 81-Place - Heathrow Scientific

Traditional cardboard freezer boxes quickly deteriorate, grow mold, and lose their structural integrity in humid laboratory environments. The Heathrow Scientific Polypropylene Film Cryogenic Freezer Box offers a vastly superior, moisture-resistant alternative that outlasts cardboard while providing secure storage for 1.5mL and 2.0mL microtubes down to ultra-low temperatures.

Manufactured from thin, durable polypropylene film, these 81-place boxes are supplied "flat-packed" to eliminate the hassle of bulky storage when not in use. They assemble in seconds and include pre-configured dividers. Engineered for extreme cold, they safely withstand vapor phase liquid nitrogen (-196°C) as well as mechanical ultra-low freezers (-80°C).

Features and Benefits

• Moisture Resistant: Will not absorb condensation, degrade, or grow mold like standard cardboard boxes during repeated freeze-thaw cycles.

• Ultra-Low Capable: Rated for use in mechanical freezers and vapor phase liquid nitrogen down to -196°C.

• Space-Saving Storage: Supplied flat-packed to drastically reduce the shelf space required for un-assembled inventory.

• Included Dividers: Each box comes complete with pre-configured 81-place dividers (12.1mm well diameter).

• Color Coded: Available in multiple bright colors to simplify visual organization of distinct cell lines or patient samples.

Specifications

Laboratory Applications

• Long-term archiving of DNA, RNA, and protein aliquots in -80°C mechanical freezers

• Deep cryogenic storage of cell lines in vapor phase liquid nitrogen (-196°C)

• High-humidity environments where standard cardboard boxes quickly fail

Frequently Asked Questions

Can these be submerged in liquid nitrogen?
No, these boxes are rated for vapor phase liquid nitrogen only. Direct submersion in liquid nitrogen may compromise the material.

Do I have to assemble the dividers?
The outer box ships flat, but the included dividers are pre-assembled and simply drop into the constructed box.

Will standard 2.0mL cryovials fit?
Yes, the 12.1mm well diameter accommodates most standard 1.5mL and 2.0mL microtubes and internally threaded cryovials.
