25-Slide Mailing & Storage Boxes with Cork-Lined Base — Blue Styrenic Thermoplastic, 20/Bag (258-5811-B10)
These blue styrenic thermoplastic slide mailing and storage boxes hold up to 25 standard 25 × 75 × 1 mm microscope slides and feature a cork-lined base that retains each slide by friction — no adhesive contacts the glass, labels, or coverslips. Supplied 20 boxes per bag under part number 258-5811-B10, they are designed for pathology consultation submissions, inter-laboratory slide transport, IHC panel shipping, and long-term slide archiving. A friction-fit lid and rigid shell provide structural protection against the compressive and impact forces of postal and courier handling.

Applications
- Pathology consultation submission: The 25-slide capacity accommodates a complete case set — H&E plus 4–6 IHC stains across 5–8 case slides — without excess empty positions that allow slide migration during transit.
- IHC and special stain panel shipping: Cork base prevents coverslip-to-glass contact and label abrasion, keeping stained slides intact and legible upon arrival.
- FISH / ISH molecular slide transport: Friction retention holds delicate molecular cytogenetics slides securely in individual positions throughout courier handling.
- Reference lab and second-opinion referrals: Rigid styrenic shell protects slides against the compressive forces of postal packaging that would crack bare slides in envelopes or bubble-wrap.
- Forensic evidence and chain-of-custody slides: Numbered slide positions support documentation requirements for autopsy and evidentiary submissions.
- Research cohort slide distribution: Multi-site histopathology studies can ship a consistent 25-slide set per case to collaborating institutions.
- Slide archiving: Blue shell color supports visual batch identification — pathology programs use color-coded boxes to designate tumor board case sets, accession date batches, or specific consultation types in multi-box storage systems.
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Aqueous buffers and saline | Good |
| Water-based staining reagents (H&E, IHC counterstains) | Good — incidental surface contact |
| Ethanol (>70%) / isopropanol | Not recommended — prolonged contact may stress styrenic shell |
| Acetone / chloroform / xylene | Not recommended |
| Aromatic or chlorinated solvents | Not recommended |
| Autoclave / steam sterilization | Not suitable |

Frequently Asked Questions
Will these boxes accept standard microscope slides from any manufacturer?
Yes — the boxes are sized for standard 25 × 75 × 1 mm microscope slides, which is the universal format used by virtually all clinical and research slide manufacturers. Slides outside this format (e.g., large-format or extra-thick slides) should be measured against the box interior before ordering.
Does the cork lining use any adhesive that could contact slide labels or stained tissue?
No — the cork base retains slides by friction fit only. There is no adhesive that contacts the slide surface, so labels, coverslips, and stained sections are not at risk of abrasion or chemical transfer during transport.
Why blue? Can color-coding help in a high-volume pathology practice?
Blue is commonly used in histopathology programs to designate specific case types, accession batches, or IHC panel sets within multi-box storage and shipping systems. Using a consistent color per case category lets accessioning and receiving staff identify and sort boxes without opening them — a meaningful efficiency gain in high-volume consultation workflows.
Are these boxes suitable for single-use-per-consultation-case, or are they intended to be reused?
The rigid styrenic construction is durable enough for reuse in archiving scenarios, but many pathology practices adopt a single-use-per-consultation-case approach for outgoing submissions to avoid cross-case contamination risk and chain-of-custody concerns. The pack size of 20 boxes per bag supports either workflow.
