100-Well Microtube Storage Box (Pack of 5)

100-Well Microtube Storage Box, -80°C Rated

The Heathrow Scientific 100-Well Microtube Storage Box delivers the highest tube-per-box capacity in the standard freezer box format, holding 100 individual 1.5mL or 2.0mL microcentrifuge tubes in a hinged-lid design with a fitted snap clasp. Rated to -80°C and dimensioned to fit standard -80°C upright freezer rack compartments, these boxes provide organized alphanumeric position tracking across all 100 wells with a frosted writing area for box-level annotation. Available in Natural, Black, Blue, Green, Yellow, Orange, and an Assorted 6-color pack. Sold in packs of 5 boxes.

Specifications

Features & Benefits

• 100-well maximum capacity: The 10x10 well array holds the most tubes per box position of any standard microtube storage format — reducing the total number of boxes required to store large sample collections and minimizing the freezer rack positions consumed by a given number of tubes.
• Hinged lid with snap clasp: The integrated hinge keeps lid and box body permanently connected, eliminating the lost-lid problem. The fitted snap clasp locks the lid securely at ultra-low temperatures, preventing accidental opening during freezer handling and maintaining the thermal isolation of tube contents during brief sorting operations.
• -80°C temperature rating: Polypropylene construction maintains structural integrity and clasp function at ultra-low temperatures, ensuring the 100-well box performs reliably throughout the storage lifecycle without lid warping, clasp failure, or well deformation.
• Alphanumeric position identification: Uniform alphanumeric well labeling (rows A-J, columns 1-10) provides quick visual identification and supports systematic sample inventory management in laboratory information systems without requiring separate position maps.
• Frosted writing area: Dedicated exterior writing surface for project name, sample set description, date, and storage condition annotation in permanent marker or adhesive label format.
• 12.3mm well diameter: Correctly sized for standard 1.5mL and 2.0mL tube bodies, providing secure individual tube retention that prevents tubes from falling out during handling and sorting operations.
• Autoclavable: Full autoclave compatibility for pre-loading sterilization of boxes used with sterile sample types including cell lines, RNA, viral vectors, and bacterial stocks.
• Seven color options: Natural, Black, Blue, Green, Yellow, Orange, and Assorted (Purple, Blue, Green, Yellow, Orange, Pink) for multi-project freezer color-coding systems.

Applications

The 100-well format is the preferred choice for large-cohort biobanking applications where maximizing tube density per freezer rack position is a direct operational cost factor. A 500-sample biobank study that would require 10 boxes in a 50-well format requires only 5 boxes in the 100-well format — halving the rack positions consumed and the time spent managing box inventories. Genomics labs archiving DNA extracts from patient cohorts or population studies use 100-well boxes to store one row per patient with 10 aliquots across columns, creating a consistent positional convention that simplifies retrieve-and-return operations. RNA preservation labs use the Natural (translucent) box to visually verify that all 100 tube positions are filled and capped before the box is placed into -80°C storage, reducing the risk of discovering missing aliquots after a long storage period. Biorepository facilities managing thousands of tubes for multicenter clinical trials use the alphanumeric 10x10 grid for LIS-compatible position tracking across entire sample collections. The Black color option is used for light-sensitive samples including fluorescence-labeled antibodies, photosensitive drug compounds, and bioluminescent reporter constructs where light penetration through translucent box walls is a concern.

Frequently Asked Questions

What is the difference between the 100-well standard box and the 100-well hinged box?

Both the standard and hinged versions of the 100-well box share identical well count, dimensions, temperature rating, and material specifications. The distinction is that all 100-well boxes in this product line feature the hinged lid with fitted snap clasp as the standard closure design. The "hinged" designation in some SKU names distinguishes this box from older open-top or removable-lid formats — all current 100-well boxes ship with the integrated hinge and snap clasp as standard.

How does the 100-well box fit in a standard -80°C upright freezer rack?

Standard -80°C upright freezer racks for 2-inch-height boxes typically have compartments approximately 5.25-5.5 inches square or rectangular. The 100-well box at 5.6 x 6.0 inches fits in rectangular rack compartments with those interior dimensions. Verify your specific freezer model's rack compartment dimensions before purchasing, as freezer rack designs vary across manufacturers. Most Thermo Fisher, Eppendorf, Panasonic, and Stirling Ultracold rack systems accommodate the 100-well box format.

Can 2.0mL tubes with attached screw caps fit in the 100-well box?

Yes. The 12.3mm well diameter accommodates the body of standard 1.5mL and 2.0mL tubes including screw-cap formats commonly used for biobank archival storage. The tube cap extends above the well opening regardless of cap type, maintaining cap accessibility for retrieval. For tubes with very large-diameter caps (such as certain 2.0mL wide-cap formats over 12mm cap OD), verify the cap will clear the adjacent well openings without interference during loading and retrieval.
