Fisherbrand 03-395-463 Cardboard Freezer Box – 25-Place, 3x3x2 in., with Drain Holes

The Fisherbrand 03-395-463 is a specialized cryogenic storage box designed for the organized archiving of 1.5 mL to 2.0 mL microcentrifuge tubes and cryovials. Measuring 3 x 3 x 2 inches, this compact box is constructed from heavy-duty, moisture-repellent cardboard, featuring a high-gloss white coating that resists the degradation caused by extreme temperature fluctuations and frost buildup. The box is supplied with a 25-place (5 x 5) cell divider, providing a secure and organized grid for sample tracking. A critical feature of the 03-395-463 is the inclusion of integrated drain holes in the base, which facilitate the rapid exit of liquid nitrogen or condensation, ensuring sample safety and extending the structural life of the box. Ideal for use in ultra-low temperature (ULT) freezers and liquid nitrogen vapor phase storage, this box is a staple for biobanking and molecular biology repositories.

Technical Performance and Design

• Moisture-Resistant Coating: The exterior is treated with a specialized water-repellent finish that prevents the cardboard fibers from absorbing condensation, maintaining structural rigidity even after multiple freeze-thaw cycles.

• Integrated Drain Holes: Features precision-punched holes in the bottom of the box to prevent the accumulation of liquid nitrogen or moisture, reducing "ice-locking" and ensuring the safety of the user during sample retrieval.

• 25-Place (5 x 5) Divider: The pre-inserted cardboard divider keeps tubes upright and separated, preventing contact between vials and facilitating easy identification using the grid system.

• Ultra-Low Temperature Compatibility: Engineered to withstand temperatures as low as -196°C, making it suitable for both mechanical freezers and vapor-phase liquid nitrogen tanks.

Key Benefits & Applications

• Space Optimization: The 3x3 footprint is ideal for smaller freezer racks or for labs that need to separate small subsets of samples without wasting the space of a standard 5x5 inch box.

• Sample Safety: The drain holes are essential for safety when removing boxes from liquid nitrogen, as they allow trapped liquid to pour out rather than creating a pressure-burst hazard.

• Universal Storage: Compatible with most standard 2-inch stainless steel freezer racks, providing a versatile solution for long-term genomic and proteomic sample archiving.

• Labeling Compatibility: The glossy white surface is optimized for use with cryo-markers and low-temperature labels, ensuring that sample data remains legible throughout the life of the box.
