Crystal Cryogenic Freezer Boxes are suitable for:

• Ultra-low freezers (–80 °C), Freezers, and Refrigerators
• Cryogenic storage (vapor phase liquid nitrogen, depending on model)

Important: Material selection determines performance at extreme temperatures. Always confirm compatibility for liquid nitrogen applications. Always verify specifications before use in liquid phase LN₂.

Crystal Cryogenic Freezer Boxes are available in

Polycarbonate (for temperatures -196ºC- to 121ºC)/Polypropylene (Plastic for temperatures to -80ºC):

• High durability and impact resistance
• Suitable for repeated use
• Excellent performance at ultra-low temperatures
• Available in -81 and -100 cell options
• With Clear Lids and Locator Grids to facilitate sample identification
• Boxes feature drain holes for venting and safety, keyed lid to prevent lid misalignment

Waterproof Hinged Fiberboard (Cardboard):

• Waterproof for longer life when repeatedly thawed and frozen
• Hinged lid to reduce chance of lid misplacement
• With -81 Cell Divider inserted
• 3 Colors available for great organization

Coated Fiberboard (Cardboard) Water Pellant:

• Cost-effective storage solution
• Suitable for –80 °C to +4ºC environments
• Ideal for short- to medium-term storage
• Supplied with and without Grid (Cell Dividers)

Crystal Cryogenic Freezer Boxes support a wide range of tube sizes, including:

• 0.5 mL to 2.0 mL cryovials
• Larger tubes up to 50 mL (depending on box height and grid format)

Common configurations include:

• 25-place (5 × 5)
• 81-place (9 × 9)
• 100-place (10 × 10)
• Others, 16-place (4 x 4), 36-place (6 x 6), 49-place (7 x 7), 64-place (8x8), 96-place (8x12)

Grid format selection depends on:

• Sample volume
• Storage density requirements
• Vial/Tube dimension

They provide:

• Clearly defined grid layouts for sample tracking
• Efficient use of freezer space
• Faster sample identification and retrieval
• Improved traceability for long-term storage

• Crystal Cryogenic Freezer Boxes support:
  • Printed grid coordinates on lids
  • Cryogenic labels for low-temperature environments
  • Barcode compatibility (on select models)
• These features help streamline inventory management and reduce sample handling errors.

Common causes include:

• Ice buildup from moisture exposure
• Frost accumulation inside the freezer
• Frequent freezer door openings

Best practices:

• Minimize freezer door opening time
• Use properly sealed containers
• Maintain regular freezer defrost cycles (if applicable)

• Important features include:
  • Verified temperature compatibility
  • Durable, low-temperature-resistant materials
  • Clearly labeled grid systems
  • Secure lid design (hinged or removable)
  • Drainage holes (for condensation or LN₂ vapor use)
  • Compatibility with freezer racks and automation systems

Plastic boxes are not only more durable than cardboard boxes, but they are also less prone to damage than cardboard boxes when sample boxes are repeatedly frozen and thawed. They also may feature a lip closure that holds the lid to the bottom of the box making spilling less likely if the box is dropped.
