Thermo Scientific Freezer Storage Box Holds 64 1.5 ml Vials Qty 8 Cryoboxes

Thermo Scientific 330821 Freezer Storage Box – 64-Place, for 1.5 mL Vials, Polycarbonate

The Thermo Scientific 330821 is a high-durability cryogenic storage solution designed for the secure organization of 1.5 mL microcentrifuge tubes and cryogenic vials. Constructed from premium, medical-grade polycarbonate, this storage box is engineered to maintain its structural integrity in extreme thermal environments, including vapor-phase liquid nitrogen (-196°C) and high-temperature autoclaving (+121°C). The 64-place (8x8) grid format provides ample spacing for each vial, preventing cap-overlap and allowing for easy retrieval even when wearing cryogenic gloves. Featuring a transparent lid for immediate sample visibility and molded-in alphanumeric indexing, the 330821 simplifies inventory management and protects valuable biological samples from mechanical damage and thermal fluctuations.

Technical Performance and Design

• 8x8 Grid Configuration: Houses up to 64 vials (1.5 mL capacity), offering a spacious layout that accommodates vials with larger caps or wrap-around labels that often crowd higher-density storage boxes.

• Cryogenic Resilience: Manufactured from impact-resistant polycarbonate that will not become brittle or crack at ultra-low temperatures, ensuring long-term protection for critical biobank assets.

• Standardized Footprint: Designed with a universal 5.25" x 5.25" (133mm) base, ensuring compatibility with standard stainless steel freezer racks used in upright and chest-style ultra-low temperature (ULT) freezers.

• Optimized Drainage and Venting: Includes integrated slots in the base to allow for rapid drainage of liquid nitrogen and moisture, as well as air-venting to prevent pressure-induced lid displacement during thawing.

Key Benefits & Applications

• Secure Sample Tracking: The high-contrast alphanumeric grid allows for precise mapping of samples, which is essential for maintaining GLP/GMP compliance in clinical and research registries.

• Thermal Stability: The vented design ensures that vials are cooled or warmed uniformly, reducing the risk of "hot spots" that can compromise the viability of sensitive biological reagents.

• Laboratory Organization: The transparent lid allows researchers to perform a visual inventory without opening the box, minimizing sample exposure to ambient temperatures and reducing frost buildup.

• Chemical Resistance: Resistant to a wide range of laboratory alcohols and mild solvents, making the box easy to decontaminate and sanitize between uses.
