Heathrow Scientific Cardboard Cryogenic Freezer Box Dividers - HS2860 Series | 49/64/81/100-Well Options

A cryobox without a divider is just a box — tubes rattle, shift, and become impossible to track by position. Heathrow Scientific Cardboard Cryogenic Freezer Box Partitions snap into any standard 5.2 × 5.2-inch cardboard cryobox to create a precise grid that holds each tube in its own indexed cell. Available in four well counts — 49 (7 × 7), 64 (8 × 8), 81 (9 × 9), and 100 (10 × 10) — these dividers let you match the insert grid to your specific tube diameter, from wide-mouth 17.5 mm vials down to standard 11.5 mm microtubes. Sold in packs of 12 to match the standard cardboard cryobox pack size, so you can outfit an entire box order in one purchase.

Features and Benefits

• Four Well-Count Options: Choose 49-well (17.5 mm ⌀), 64-well (15 mm ⌀), 81-well (12 mm ⌀), or 100-well (11.5 mm ⌀) to match your specific tube outer diameter.

• Cardboard Construction: Lightweight, economical cardboard inserts that pair naturally with Heathrow cardboard cryoboxes for a fully disposable storage system.

• Indexed Grid Cells: Each well position corresponds to an alphanumeric coordinate on the cryobox base, enabling sample-level tracking in LIMS and inventory databases.

• Snap-Fit Assembly: Pre-scored interlocking slots assemble quickly by hand — no tools, adhesives, or special training required.

• 12-Pack to Match Box Orders: Sold in packs of 12, matching the standard cardboard cryobox pack quantity for one-to-one pairing at checkout.

Specifications

Laboratory Applications

• Outfitting new cardboard cryobox purchases with matching dividers for organized microtube and cryovial freezer storage

• Replacing worn or damaged dividers in existing cardboard cryoboxes that have lost their grid structure over time

• Customizing well diameter to match non-standard tube sizes — the 49-well (17.5 mm) fits wider vials that slip through 81-well or 100-well grids

Frequently Asked Questions

Which divider fits 1.5 mL and 2.0 mL microcentrifuge tubes?
The 81-well (HS2860H, 12 mm diameter) and 100-well (HS2860E, 11.5 mm diameter) both accept standard 1.5/2.0 mL microtubes. Use 100-well for maximum density or 81-well for a slightly looser fit that makes tube insertion easier when wearing gloves.

Do these dividers fit both the 50 mm and 75 mm cryoboxes?
Yes. The dividers fit the standard 5.2 × 5.2-inch cryobox footprint regardless of box height (50 mm or 75 mm). The divider height is shorter than the box — the tubes extend above the divider and the lid holds them in place.

Can I reuse the dividers after autoclaving?
Cardboard dividers are not autoclavable. They are designed as disposable inserts. For reusable, autoclavable storage, consider polypropylene or polycarbonate cryoboxes with molded wells.
