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

25-Position Cardboard Freezer Storage Boxes for 2.5 mL Transport Vials — White, 12/Bag (240-8225-000)

These white cardboard freezer storage boxes provide organized, individual-access archiving for 2.5 mL transport vials in a 25-position 5×5 grid, rated for both -20°C and -80°C cryo storage environments. Supplied non-sterile in packs of 12, they are engineered for biobank, biorepository, and clinical specimen archiving workflows where reliable vial identification and random-access retrieval are daily requirements. The white cardboard surface readily accepts permanent marker, adhesive labels, and printed box tags to support chain-of-custody documentation and position mapping.

Technical Specifications

Applications

• Long-term cryo archiving of 2.5 mL transport vials at -20°C and -80°C in upright freezer drawers and chest freezer baskets
• Biobank and biorepository specimen management requiring random-access retrieval of individual vials without disturbing adjacent positions
• Clinical specimen archiving of serum, plasma, and whole-blood aliquots organized by 25-position numbered grid
• Molecular diagnostics archives for DNA, RNA, and extracted specimen panels with permanent-marker or label-based position mapping
• Pharmaceutical biorepository programs managing large inventories of archived reference specimens

Compatibility

These freezer storage boxes are designed as a matched companion to the Caplugs® Evergreen 240-3007 and 240-3010 families of 2.5 mL transport vials, including the 240-3007-L60 (lavender cap) and 240-3007-R60 (red cap) configurations. The 25-well geometry is sized to the outer diameter of these transport vials, holding each tube upright and independently accessible. Procuring vials and storage boxes together from a single authorized source streamlines kitting, simplifies purchase orders, and ensures dimensional compatibility between the vial and the box well.

Quality & Procurement

Made in USA (California), these Caplugs® Evergreen freezer storage boxes are constructed from cardboard selected for its low thermal mass and dimensional stability through repeated freeze-thaw cycling — properties that make cardboard the established material standard for laboratory cryo storage boxes at -20°C and -80°C. The box geometry stacks neatly in standard upright -80°C freezer drawers and -20°C chest freezer baskets, maximizing vial density per unit of freezer shelf space — an important procurement consideration for high-volume biorepository programs. LabSupplies.com is an authorized dealer of Caplugs® Evergreen consumables and ships from USA inventory, with tiered pricing available for institutional, hospital, and grant-funded laboratory accounts.

Frequently Asked Questions

Are these storage boxes compatible with -80°C ultra-low temperature freezers?
Yes — the cardboard construction is rated for both -20°C and -80°C environments and is dimensionally stable through repeated freeze-thaw cycles, making these boxes suitable for long-term ultra-low temperature archiving.

Which vials fit in the 240-8225-000 storage box?
The 25-position grid is sized for 2.5 mL transport vials, with confirmed fit for the Caplugs® Evergreen 240-3007 and 240-3010 vial families. If you are using a different brand or format of 2.5 mL transport vial, verify the vial outer diameter against the well dimensions before ordering in quantity.

How are positions in the box identified for specimen tracking?
The white cardboard surface accepts permanent marker and standard adhesive labels directly, allowing labs to apply custom box IDs, position maps, lot numbers, and chain-of-custody markings without additional supplies.

Are these boxes sterile, and can they be reused?
These boxes are supplied non-sterile and are intended for single-use-per-aliquoting-run allocation, which eliminates reuse tracking overhead and is consistent with biobank best practices for specimen integrity and contamination control.
