Rock Solid Heavy Duty Cryogenic Storage Box Handles 36 Plastic Lab Test Tubes Sleek Freezer Rack With Extreme Cold Endurance And Built Tough Professional Performance

Heavy Duty 36 Slot Cryogenic Tube Rack For Lab Freezers
✔️ Blue plastic crate holds 36 vials withstands extreme cold

This neat freezer rack you depend on organizes thirty six microcentrifuge tubes without crowding your work station. You slide it directly into ultra low temperature units where the tight seal stops liquids from escaping during long haul storage runs.

✅ Low temperature endurance protects fragile biological specimens across extended freezing cycles
✅ Sturdy blue shell resists cracking while handling heavy loads inside walk in coolers
✅ Precision cut holes let you spot your target vials fast without digging through rows
✅ Smooth finish prevents moisture buildup so cleanup only takes a quick wipe down

💡 Why do scientists find sealed tube organizers handy for liquid nitrogen storage?
Cheaper materials stop thermal shock from shattering expensive tooling when temperatures drop quickly.
- Polypropylene flexibility keeps alignment tight during rapid freeze thaw sequences across busy bench tops
- Open channel design pushes cold air around every vial location for faster cooling rates
- Leak proof walls block moisture ingress so your archived cultures stay viable longer
