Fisherbrand Cryo Freezer Box 5 x 5 x 2 in. with Bottom Drain Holes and Tight Lid Case of 100 Boxes

Fisherbrand 2-Inch Cardboard Cryo Freezer Boxes with Drain Holes, 5 x 5 x 2 in. (03-395-455) – Case of 100

The Fisherbrand 2-Inch Cardboard Cryo Freezer Boxes (03-395-455) are high-density, water-resistant storage containers designed for ultra-low temperature (ULT) sample archiving, biobanking, and cryogenic storage. Constructed from durable, heavy-duty cardboard with a liquid-resistant coating, these 5 x 5 x 2 inch (13 x 13 x 5 cm) boxes withstand extreme thermal stress down to minus 196 degrees Celsius (liquid nitrogen vapor phase). Featuring integrated bottom drain holes, these boxes allow rapid liquid nitrogen and meltwater drainage during thawing cycles, preventing waterlogging and structural softening. Supplied as an economical bulk case of 100 boxes with tight-fitting lids, this consumable line provides reliable, long-term organization for research, clinical, and industrial biological repositories.

Technical Performance & Structural Design

• Moisture-Resistant Heavy-Duty Cardboard: Formulated with a protective outer coating that resists frost buildup, ambient condensation, and structural warping during repeated freeze-thaw cycles.
• Integrated Bottom Drain Holes: Features precision-cut drainage ports on the bottom surface to ensure fast liquid nitrogen discharge and meltwater drainage upon removal from cryogenic freezers.
• Tight-Fitting Protective Lid: Includes a snug-fitting telescoping lid that stays securely in place during rack transfers while shielding samples from ambient dust and frost accumulation.
• Standard Universal Footprint: Measures 5 x 5 x 2 inches, ensuring full compatibility with standard upright and chest freezer storage racks and standard grid dividers (e.g., 81-place or 100-place inserts).
