2.5 mL Storage Boxes, PP, White — 240-8225-000 | 12/Bag | Caplugs® Evergreen

Freezer Storage Boxes for 2.5 mL Transport Vials, 25-Position — Cardboard, White, 12/Bag

Technical Narrative

The Caplugs® Evergreen 240-8225-000 is a 25-position cardboard freezer storage box designed for organized -20°C and -80°C archiving of 2.5 mL transport vials — including the Caplugs® Evergreen 240-3007 and 240-3010 transport vial families. The 25-well 5×5 grid holds each vial upright in a defined numbered position, enabling individual vial access without disturbing adjacent vials — a critical feature for biobank and biorepository programs where random-access retrieval of individual specimens is a daily workflow requirement. The white cardboard surface accepts permanent marker, adhesive labels, and printed box tags for batch identification, position mapping, and chain-of-custody documentation.

Cardboard construction is the material standard for laboratory freezer storage boxes at -20°C and -80°C — cardboard's low thermal mass and dimensional stability under repeated freeze-thaw cycling outperform many polymer alternatives for dense freezer drawer stacking. The box geometry is designed to stack neatly in standard -80°C upright freezer drawers and -20°C chest freezer baskets, maximizing the number of vials stored per linear foot of freezer shelf space — a critical procurement consideration for biorepository programs managing tens of thousands of archived specimens.

At $51.32 per 12/Bag — $4.2766 per box — the delivers organized cryo vial archiving at economics that support single-use-per-aliquoting-run allocation without reuse overhead. Designed to pair with: 240-3007-L60 (2.5 mL transport vials, 7 mL PP Lavender cap, 1000/Bag, $130.32/Bag); 240-3007-R60 (2.5 mL transport vials, 7 mL PP Red cap, 1000/Bag, $130.32/Bag) — enabling matched vial-and-box procurement from a single vendor for complete specimen archiving systems.

Workflow Compatibility & Storage Applications —

The 25-position freezer storage box is designed for 2.5 mL transport vials and compatible with the following storage and archiving workflows:

Cardboard construction is suitable for -20°C and -80°C frozen storage. Keep dry — avoid direct liquid contact. Not autoclave-compatible. The white surface accepts permanent marker for box labeling.

Chemical & Environmental Resistance — Cardboard (White)

Cardboard construction is suitable for frozen storage at -20°C and -80°C. Keep dry and away from liquid immersion.

Clinical & Research Laboratory Applications

The freezer storage box serves biobank and biorepository programs archiving serum, plasma, DNA, and RNA specimens at -20°C and -80°C; clinical reference laboratories maintaining long-term specimen archives for reflex and repeat testing; molecular diagnostics labs archiving extracted nucleic acids; pharmaceutical and biotech biorepositories storing compound, reference standard, and patient sample aliquots; forensic labs maintaining evidence specimen archives; and academic research programs managing longitudinal biospecimen cohorts. The 12/Bag format supports moderate-volume archiving programs adding 25–100 specimens per batch.

Frequently Asked Questions — Caplugs® Evergreen

What vial sizes fit the freezer storage box?

The is designed for 2.5 mL transport vials in the Caplugs® Evergreen 240-3007 and 240-3010 families. Always validate fit with your specific vial OD before bulk purchase — request a free sample box to confirm before committing to volume.

Is the compatible with -80°C ultra-low temperature freezers?

Yes. Standard laboratory cardboard freezer boxes are rated for -80°C ultra-low temperature storage and are the material of choice for ULT freezer archiving across biobank and biorepository programs worldwide. The maintains structural integrity across repeated -80°C freeze-thaw cycles under normal usage conditions. Keep the box dry — avoid direct liquid contact or condensation accumulation, which can compromise cardboard structural integrity over extended storage periods.

Can I label the box and each vial position?

Yes. The white cardboard exterior accepts permanent marker (Sharpie®), ballpoint pen, and adhesive labels for box-level identification. The 25-position 5×5 grid provides a numbered position reference for vial mapping — document position assignments in your laboratory information system (LIS) or on a printed box map for chain-of-custody and retrieval efficiency.
