100-Slide Heavy-Duty Foam-Lined Mailing Boxes — PPC, White, 4/Bag (258-6188-W30)
These heavy-duty 100-slide mailing boxes feature a polypropylene copolymer (PPC) shell and a foam-lined base that holds each standard 25 × 75 mm microscope slide in individual friction-retention positions — protecting slides through courier handling without adhesive or label abrasion. The white color variant in the Caplugs® Evergreen range provides the highest label-contrast surface of the series, making part number 258-6188-W30 the preferred choice for LIS-printed barcode labels, adhesive case ID stickers, and any workflow driven by printed box identification rather than visual color routing. Each bag contains four boxes, suited to multi-case batch shipping programs at reference laboratories, pathology outreach networks, and research institutions.

Applications
- Reference laboratory outreach shipping — 100-slide capacity covers 4–8 complete case sets per box, suited to weekly accession batches
- LIS-integrated slide management — white shell provides maximum contrast for adhesive barcode and printed case ID labels
- Tumor board preparation — label-identified multi-case slide sets distributed to multiple reviewers in a single labeled box
- Bulk IHC outsourcing — PPC impact resistance protects stained slides through repeated courier handling to contract staining labs
- Cold-chain batch shipping — PPC maintains structural integrity at −20°C for immunofluorescence frozen sections and cryostat sections requiring sub-zero transit
- Multi-site research cohort distribution — uniform 100-slide white boxes support standardized accessioning across distributed study sites
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Aqueous buffers / saline | Excellent |
| Dilute acids and bases | Excellent |
| Alcohols (e.g., 70% ethanol) | Good — short-term contact |
| Cold storage at −20°C | Excellent — PPC retains structural integrity |
| Chlorinated / aromatic solvents (e.g., xylene, chloroform) | Not recommended for prolonged contact |
Quality & Procurement
Made in USA, these Caplugs® Evergreen slide mailing boxes are manufactured from impact-resistant PPC resin in California under ISO 9001 quality management. The PPC formulation is free of materials that compromise structural integrity at low temperatures, and the heavy-duty shell design is engineered specifically for the stresses of courier and postal shipping rather than benchtop-only storage. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, with tiered volume pricing available for reference laboratories, hospital systems, and institutional procurement programs. Also available in Blue (258-6188-B30) and Red (258-6188-R30) for color-coded routing workflows.
Frequently Asked Questions
What makes the white color the right choice over the blue or red variants?
White provides the highest contrast surface for adhesive barcode labels and LIS-printed case ID stickers. Laboratories that identify boxes primarily through printed labels — rather than visual color routing — typically find white the most legible and scan-reliable option. Blue and red variants serve workflows where color-coded sorting is the primary routing method.
Will the PPC shell hold up at −20°C during cold-chain shipping?
Yes. Polypropylene copolymer retains its structural integrity and impact resistance at −20°C, making these boxes appropriate for cold-chain batch shipping of immunofluorescence frozen sections, cryostat sections, and other slides that must remain sub-zero throughout transit. Standard styrenic plastic boxes can become brittle and fracture at low temperatures; the PPC shell flexes rather than shatters under courier handling forces.
How does the foam base retain slides — will it damage labels or stained coverslips?
The foam lining holds each slide by friction in its individual position, with no adhesive involved. Slides seat cleanly and release without label abrasion or reagent transfer, preserving both the slide label and the coverslipped preparation at the receiving site.
How many complete case sets fit in one box, and is the non-sterile format a concern for diagnostic slides?
At 100-slide capacity, a single box typically holds 4–8 complete case sets depending on section count per case, making the format well-matched to weekly outreach batches. Non-sterile is the standard and appropriate format for fixed, stained, and coverslipped diagnostic or research slides; sterility is not a relevant requirement for this application.
