Heavy-Duty 100-Slide Storage Mailing Boxes with Foam Lined Base, PPC, White — 258-6188-W30 | 4/Bag

Technical Narrative

The Caplugs® Evergreen is the white color variant in the heavy-duty 100-slide PPC foam-lined mailing box range — completing the Blue (258-6188-B30) and Red (258-6188-R30) options with a neutral-base format optimized for adhesive barcode and printed case ID label systems. White provides the highest label-contrast surface of the three colors, making it the default choice for reference laboratory outreach programs, LIS-integrated slide management systems, and any workflow where printed case labels are the primary box identification method rather than color-coded visual routing.

PPC (Polypropylene Copolymer) construction provides significantly greater impact resistance than standard styrenic plastic slide boxes — the shell flexes under courier handling impact forces rather than fracturing, protecting all 100 slides in transit. PPC also maintains structural integrity at -20°C, supporting cold-chain batch shipping programs for immunofluorescence frozen sections and cryostat sections where slides must remain sub-zero throughout the shipping chain. The foam base provides individual slide friction retention without adhesive — slides seat cleanly and release without label abrasion or reagent transfer at the destination.

At $25.18 per 4/Bag — $6.2944 per box — the delivers 100-slide heavy-duty protection at a per-box cost suited to multi-case batch shipping programs. Also available: 258-6188-B30 (Blue, 4/Bag, $25.18/Bag); 258-6188-R30 (Red, 4/Bag, $25.18/Bag).

Technical Specifications — Caplugs® Evergreen

Slide Transport & Storage Workflow Compatibility —

White provides maximum label-contrast for adhesive barcode labels and printed case ID stickers — the preferred choice for reference laboratory outreach programs using LIS-printed label systems. The 100-slide capacity suits multi-case batch shipping workflows:

Fits standard 25 × 75 mm slides. For biological specimen postal compliance, confirm IATA P650 secondary containment requirements. For single-case consultation shipping, see the 25-slide format (258-6025 family).

Chemical Resistance — Polypropylene Copolymer (PPC)

PPC shell with foam lining. PPC resists incidental reagent contact from stained slides. Not suitable for solvent immersion.

Pathology & Research Laboratory Applications

The serves reference laboratory outreach programs shipping weekly accession slide batches; hospital pathology programs submitting multi-case consultation sets; research institutions distributing slide cohorts to multi-site partners; IHC outsourcing programs shipping bulk plate batches; tumor board and multidisciplinary team case preparation; forensic pathology chain-of-custody slide distribution; and archive retrieval programs handling bulk slide pulls for review.

Frequently Asked Questions — Caplugs® Evergreen

What is the advantage of white over blue or red for 100-slide boxes?

All three 100-slide PPC foam-lined boxes are identical in construction and protection level. Color choice is workflow-driven. White provides maximum label-contrast for adhesive barcode and printed LIS labels — the best choice for systems where labels are the primary box identification method. Blue (258-6188-B30) designates specific case categories or accession batches visually. Red (258-6188-R30) flags urgent or priority batch shipments. Choose based on your laboratory's color-coded routing protocol.

How many case sets fit in the 100-slide box?

This depends on slides per case in your protocol. Typical ranges: 5–8 slides per case = 12–20 cases per box; 10–15 slides per case = 6–10 cases per box; H&E only = up to 100 single-slide cases per box. For single-case consultation shipping (typically H&E + 4–12 IHC stains), the 25-slide format (258-6025 family) is more economical.

Is the PPC box suitable for frozen slide transport at -20°C?

Yes. PPC maintains structural integrity at -20°C — unlike standard styrenic thermoplastic which becomes brittle at sub-zero temperatures. The is suitable for cold-chain slide distribution programs where slides must be maintained at -20°C during shipping. For liquid nitrogen temperature transport, use purpose-built cryo containers.
