Cole-Parmer Freezer Box Plastic 36 x 15 ml Total of 3 Boxes

Description

Cole-Parmer PolarSafe Polypropylene Centrifuge Tube Freezer Storage Box – 36-Place, 15 mL, Blue Grid, Clear Lid (MPN: EW-04396-55)

The Cole-Parmer EW-04396-55 (also cataloged as 04396-55) is a heavy-duty, laboratory-grade freezer storage box precision-engineered to organize and protect 15 mL conical centrifuge tubes inside extreme temperature environments. Molded from high-durability, impact-resistant virgin polypropylene (PP), this cryogenic storage vault features a 6 x 6 well array that securely anchors up to 36 individual 15 mL tubes (maximum well diameter of 19.8 mm). The box is equipped with an optically transparent, high-clearance lid featuring a blue indexed insert and bold numeric grids for instantaneous, error-free sample mapping. Built to handle standard automated archiving racks, this autoclave-safe unit delivers premium structural stability across vast temperature extremes without warping, cracking, or breaking.

Technical Performance and Design

• Ultra-Low Deep Freeze Stability: Fabricated from high-molecular-weight polypropylene rated to withstand continuous, structural deep-freeze storage down to minus 90 C (minus 130 F), preventing material embrittlement or structural stress fractures in ultra-low freezers.

• Integrated Alphanumeric Index Grid: Features an easy-to-read, bold numeric locator grid permanently printed onto the inner colored deck module. This setup permits immediate, mistake-free sample identification, audit tracking, and positioning validation without lifting the container lid.

• Writable Matte Boundary Zones: The upper top profile of the plastic structural housing includes a dedicated, high-contrast matte white labeling segment, enabling lab technicians to apply cryogenic tape labels or write directly on the frame with fine permanent laboratory marker pens.

• Standard 4-Inch High-Ramp Form Factor: Manufactured with a standardized outer footprint (approximately 5.75 x 5.75 x 4.875 inches) designed to slide directly into standard 4-inch chest or upright chest mechanical freezer racks, chest freezer drawers, and liquid nitrogen vapor storage trays.

Key Benefits and Applications

• Conical Tube Storage Management: Highly optimized for organizing, banking, and inventory-tracking expensive biological assays, cell culture pelleted stocks, and active liquid reagents held within 15 mL tubes.

• Steam Autoclave-Safe Robustness: Capable of undergoing intensive multi-cycle steam autoclaving routines (122 C or 252 F) for effortless chemical-free decontamination, material scrubbing, and cell-trash cleanup passes.

• Condensation-Free Identification: The optical transparency of the outer top lid lets technicians verify filling limits and inspect sample levels at a glance before moving the unit into ambient humidity zones.

• Impact-Resistant Core Integrity: Polypropylene dividers offer superior drop protection over traditional paperboard grid boxes, eliminating the risk of structural tearing, soggy base failures, or mold growth from freezer frost melt-offs.
