Heavy-Duty 25-Slide Storage & Mailing Boxes — Foam-Lined, PPC, Blue (258-6025-B30), 5/Pack
These heavy-duty 25-slide storage and mailing boxes are constructed from Polypropylene Copolymer (PPC) with a foam-lined base that holds each standard 25 × 75 mm microscope slide in its own friction-retention pocket. Supplied non-sterile in packs of five, they are engineered for pathology consultation submissions, inter-laboratory slide transport, and cold-chain archive programs where shell breakage during courier handling would put irreplaceable tissue sections at risk. The blue shell integrates cleanly into multi-color slide box systems used to designate active consultation cases, current accession batches, or specific diagnostic categories.

Applications
- Pathology consultation submissions — 25-slide capacity accommodates a complete case set of H&E and multiple IHC stains across several levels
- Inter-laboratory slide transport via courier or postal services where drop and compression forces would crack standard styrenic slide boxes
- Cold-chain distribution of immunofluorescence frozen sections and cryostat sections requiring −20°C maintenance through the shipping chain
- Fragile preparation transport — foam pockets prevent slide-to-slide contact, protecting FISH preparations, coverslipped IHC sections, and immunofluorescence slides from coverslip-edge chipping and reagent transfer
- Multi-color slide box archive programs where blue designates a specific accession batch, diagnostic category, or active case status
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Aqueous buffers / saline | Excellent |
| Dilute acids and bases | Excellent |
| Alcohols (ethanol, isopropanol) | Good — short-term contact |
| Cold storage (−20°C) | Suitable — PPC retains impact resistance at sub-zero temperatures |
| Chlorinated solvents (xylene, chloroform) | Not recommended |
| Acetone | Not recommended |
Quality & Procurement
Made in USA (California), these Caplugs® Evergreen slide boxes are manufactured under ISO 9001 quality management from BPA-free, phthalate-free PPC resin. PPC's superior toughness versus standard styrenic thermoplastics is the defining characteristic of the heavy-duty designation — the shell absorbs the drop and compression forces of courier sorting environments without cracking, providing reliable protection for irreplaceable diagnostic preparations. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered pricing available for high-volume pathology departments, reference laboratories, and institutional procurement programs.
Frequently Asked Questions
Why choose PPC over a standard plastic slide box for mailing?
Polypropylene Copolymer provides significantly greater impact resistance than standard styrenic slide box materials. During courier sorting and postal handling, packages are subjected to drop and compression forces that can crack conventional slide boxes — PPC absorbs those forces without shell failure, making it the appropriate choice whenever slides are irreplaceable or breakage is clinically unacceptable.
Will standard 25 × 75 mm microscope slides fit securely?
Yes. These boxes are sized for standard 25 × 75 × 1 mm microscope slides. The foam-lined base provides individual position friction retention, so each slide seats cleanly and releases at the destination without label abrasion, coverslip disturbance, or mounting medium transfer between slides.
Are these boxes suitable for frozen slide storage or cold-chain shipping?
Yes. PPC retains its structural integrity and impact resistance at −20°C, making the 258-6025-B30 suitable for frozen slide storage and cold-chain distribution programs involving immunofluorescence frozen sections or cryostat sections that must remain at sub-zero temperatures throughout the shipping chain.
Are other colors available in this same 25-slide heavy-duty format?
Yes. The same heavy-duty PPC construction and foam-lined design is available in Red (258-6025-R30) and White (258-6025-W30), allowing laboratories to implement multi-color coding systems without mixing box types or construction levels.
