Southern Labware Cryo Freezer Box 100 Place PC Pack of 5 Freezer Boxes

Southern Labware Polycarbonate Cryogenic Freezer Storage Box – 100-Place, 10 x 10 Array, Clear Keyed Lid, Numeric Index Grid, Ultra-Low Temperature Stability (MPN: PPP2-100)

The Southern Labware PPP2-100 (also cataloged as PB2-100 across wholesale distribution networks) is a high-durability, laboratory-grade cryogenic storage box precision-engineered to organize and protect micro-volume samples inside extreme thermal environments. Fabricated from premium, impact-resistant virgin polycarbonate, this 100-place organizer features a 10 x 10 well grid array optimized to hold standard 1.2 mL to 2.0 mL cryogenic storage vials and screw-cap microtubes. The box includes an optically transparent lid complete with a permanent, bold alphanumeric locator index printed directly across the surface for mistake-free mapping. Outfitted with specialized base drainage pathways, this autoclavable container serves as a robust, long-lasting replacement for legacy paperboard freezer boxes across multi-user archiving lines.

Technical Performance and Design

• Cryogenic Temperature Horizon Stability: Molded from heavy-duty polycarbonate engineered to maintain its structural flexibility and impact strength across vast temperature scales, supporting applications from ultra-low vapor-phase liquid nitrogen storage at minus 196 C up to high-temperature steam autoclaving at 121 C.

• Keyed Anti-Misalignment Lid Profile: The transparent top cover is mechanically keyed to seat onto the colored grid base in only one specific directional orientation. This structural layout eliminates the risk of accidental 90-degree or 180-degree lid rotation errors, keeping printed index marks perfectly aligned with the samples below.

• LN2 Liquid Drainage and Venting Voids: The lower corner sections and well partitions are designed with structural drainage slots and ventilation holes. These openings allow trapped liquid nitrogen or condensation frost melt-off to escape cleanly during retrieval cycles, boosting safety and reducing ice accumulation.

• Standard 2-Inch Rack Form Factor: Manufactured to precise external boundaries (5.25 x 5.25 x 2.0 inches) that fit seamlessly into standard 2-inch upright chest freezer drawers, horizontal mechanical cryogenic racks, and liquid nitrogen vapor storage trays.

Key Benefits and Applications

• Long-Term Biorepository Banking: The premier storage template for housing delicate cell line backups, primary tissue isolates, and sensitive genetic extracts held long-term inside vapor-phase LN2 dewars or ultra-low mechanical freezers.

• Cardboard Replacement Efficiency: Polycarbonate structural walls resist water absorption, eliminating the soggy base breakdowns, structural bowing, and ambient mold growth common to traditional fiberboard dividers.

• High-Contrast Map Auditing: Boldly numbered surface grid tracks enable rapid manual inventory scans and fast specimen positioning audits without needing to fully expose cold vials to room-temperature humidity zones.

• Self-Standing and Round Vial Compatibility: Well shapes accept both round-bottom and self-standing locking cryovials, allowing for smooth tube insertion and removal using standard laboratory mechanical extraction forceps.
