Heathrow Scientific Cardboard Dividers for 15mL & 50mL Tube Storage Box - HS2860 Series

The standard cryobox dividers stop at microtube diameters, leaving 15 mL and 50 mL conical tubes without a matching grid insert. Heathrow Scientific Cardboard Tube Storage Box Partitions bridge that gap with two purpose-built configurations: a 36-well grid (23 mm wells) for 15 mL conicals and a 16-well grid (35 mm wells) for 50 mL conicals. Designed to drop into the Heathrow HS2860M tall-format cardboard storage box (sold separately), these dividers keep large tubes upright, separated, and mapped to a grid — the same position-based tracking workflow your lab already uses for microtube cryoboxes, scaled up for centrifuge-size containers.

Features and Benefits

• Two Configurations: 36-well (23 mm ⌀) for 15 mL conical tubes and 16-well (35 mm ⌀) for 50 mL conical tubes — matching the two most common centrifuge tube sizes.

• Designed for HS2860M Box: Drop-in fit for the Heathrow tall-format cardboard storage box, creating a complete organized storage system for large tubes.

• Interlocking Cardboard Assembly: Pre-scored slots snap together by hand in seconds — no tools or adhesives needed.

• Grid-Based Tracking: Each well position enables coordinate-based sample logging, extending your microtube LIMS workflow to 15 mL and 50 mL formats.

• 10-Pack to Match Box Orders: Sold in packs of 10, matching the HS2860M box pack quantity for convenient one-to-one ordering.

Specifications

Laboratory Applications

• Organized freezer archiving of 15 mL conical tubes containing cell pellets, concentrated DNA/RNA, and tissue lysates

• Structured storage of 50 mL conical tubes holding buffer stocks, media aliquots, and large-volume clinical specimens

• Clinical lab specimen management where 15 mL and 50 mL centrifuged samples require traceable, position-indexed freezer storage

Frequently Asked Questions

Do these dividers fit the standard 50 mm or 75 mm cryoboxes?
No. These dividers are sized for the larger HS2860M tall-format box (5.7 × 5.7 in footprint). They will not fit standard 5.2 × 5.2-inch microtube cryoboxes.

Can I use the 36-well divider with 50 mL tubes?
No. The 23 mm wells in the 36-well divider are too narrow for 50 mL conical tubes (which have a ~30 mm body diameter). Use the 16-well divider (HS2860P) with 35 mm wells for 50 mL tubes.

Are these dividers reusable?
They can be reused if they remain structurally intact, but cardboard dividers are designed as economical disposable inserts. Replace them when the cardboard softens or slots become loose from repeated handling.

Quality Assurance

Heathrow Scientific cardboard dividers are die-cut for consistent slot alignment and inspected for well-diameter accuracy and snap-fit assembly reliability across every production lot.
