Heathrow Scientific 100-Well Microtube Storage Box - 120201 Series | Autoclavable, Cryogenic-Safe to -80°C

Losing track of microtubes across multiple racks and trays slows down every step from sample retrieval to data logging. The Heathrow Scientific 100-Well Microtube Storage Box arranges up to 100 microcentrifuge tubes in a clean 10 × 10 alphanumeric grid, giving researchers and technicians instant coordinate-based access to every vial. Built from autoclavable polypropylene that tolerates temperatures as low as −80 °C, these boxes move seamlessly between ultra-low freezers, water baths, and benchtop workflows. A friction-fit lid keeps contents secure during transport, while a frosted labeling area on the exterior lets you mark box contents with a standard lab pen. Available in four vivid colors, each pack of five boxes supports color-coded storage strategies that simplify inventory across shared labs and biobanking facilities.

Features and Benefits

• 100-Well Capacity (10 × 10 Grid): Organizes up to 100 microcentrifuge tubes (1.5 mL or 2.0 mL) in a single box, reducing the number of storage containers needed in crowded freezers.

• Polypropylene Construction: Resists cracking from repeated freeze-thaw cycling and stands up to common laboratory solvents, dilute acids, and alcohols without degradation.

• Cryogenic-Rated to −80 °C: Engineered for reliable performance in ultra-low temperature mechanical freezers and dry-ice transport containers without embrittlement.

• Autoclavable (121 °C): Withstands standard gravity and liquid autoclave cycles at 121 °C / 250 °F, enabling thorough decontamination for reuse in BSL-2 and BSL-3 settings.

• Alphanumeric Coordinate System: Molded row and column markings let you cross-reference tube positions with LIMS records, lab notebooks, and electronic sample-tracking databases.

• Friction-Fit Snap-On Lid: Secure closure prevents accidental lid separation during handling and stacking, protecting samples from contamination and dislodgement.

• Frosted Labeling Area: Dedicated writing surface on the box exterior accepts pencil, pen, and permanent marker, so you can label contents without adhesive stickers that peel at low temperatures.

• Stackable and Color-Coded: Uniform footprint stacks neatly in freezer racks, and four color options (Blue, Green, Yellow, Orange) enable instant visual sorting of projects, users, or sample categories.

Laboratory Applications

• High-density cryogenic storage of 1.5 mL and 2.0 mL sample tubes in −80 °C ultra-low freezers, maximizing vial count per shelf position

• Biobanking and clinical biorepository workflows where color-coded boxes segregate patient cohorts, tissue types, or collection time points

• PCR and molecular biology sample organization during multi-plate experiments requiring rapid tube identification by grid coordinate

• Teaching laboratories where multiple student groups share freezer space and need an intuitive color-based system to distinguish their stored samples

• Veterinary and environmental testing labs that archive field-collected samples in compact, stackable containers for long-term cold storage

Frequently Asked Questions

How many tubes does the 100-Well Storage Box hold?
Each box accommodates up to 100 microcentrifuge tubes arranged in a 10 × 10 grid. The 12.3 mm well diameter fits standard 1.5 mL and 2.0 mL tubes from all major manufacturers.

What is the difference between the 81-Well and 100-Well boxes?
The 100-Well box uses a 10 × 10 layout with a slightly larger footprint (5.6 × 6.0 in versus 5.1 × 5.1 in), holding 19 more tubes per box. Both models share the same well diameter, temperature rating, and material.

Can I autoclave these boxes with tubes inside?
The box itself withstands 121 °C autoclave cycles. However, check that the tubes and their caps are also autoclave-rated before sterilizing a loaded box. Remove any heat-sensitive cap inserts first.

Will this box fit standard freezer racks?
The 5.6 × 6.0 in footprint fits most upright and chest freezer racks designed for standard 2-inch or 3-inch cryoboxes. Verify your rack's internal bay dimensions before purchasing in quantity.
