One-Slide Mailer — Polypropylene, Natural, 50/Bag (240-3071-030)
The Caplugs® Evergreen one-slide mailer is a single-slide transport and mailing enclosure precision-molded from virgin polypropylene (PP) to protect standard 25 × 75 × 1 mm microscope slides during postal and courier transit. The friction-fit snap-close lid creates a secure mechanical closure that resists accidental opening under typical package-handling stresses, while the PP shell absorbs impact forces that would crack a bare glass slide in a standard envelope or bubble-wrap shipment. Supplied non-sterile in convenient 50/Bag format, these mailers are well-suited to histopathology consultation submissions, cytology referrals, and inter-laboratory IHC or immunofluorescence slide sharing.

Applications
- Histopathology consultation submissions: Single-slide enclosures prevent cross-contact between H&E-stained sections and special-stain slides during inter-facility transport.
- Cytology and Pap smear transport: The friction-fit closure protects slide labels and coverslips through postal and courier handling for cervical cytology, sputum, and BAL specimens.
- Immunofluorescence (IF): Ideal for frozen-section kidney, skin, and direct IF slides; polypropylene is inert to mounting media and coverslip adhesives.
- Immunohistochemistry (IHC): Single-specimen packaging for tumor marker and biomarker-stained slides sent for inter-laboratory review or second-opinion consultation.
- Research specimen sharing: Cost-effective single-use protection for FISH, ISH, and other special-technique slides shared across academic or multi-site study networks.
- Forensic pathology chain-of-custody transport: The labeling-ready outer surface accepts permanent markers, adhesive labels, and barcode stickers to support documentation from originating lab through to the receiving pathologist.

Frequently Asked Questions
What slide size do these mailers accommodate?
Each mailer is designed for one standard 25 × 75 × 1 mm microscope slide — the format used in virtually all clinical histology, cytology, and research applications. Non-standard or oversized slides may not fit securely.
Are these mailers appropriate for sending slides through the postal mail?
Yes. The friction-fit snap-close lid resists accidental opening under normal package-handling stresses, and the polypropylene shell absorbs impact forces that would crack a bare glass slide shipped in an envelope or bubble wrap. The outer surface also accepts labels and barcode stickers to support chain-of-custody documentation requirements.
Can I load a coverslipped slide without damaging the coverslip?
Polypropylene is inert to standard mounting media and coverslip adhesives, so incidental contact during loading will not compromise the mailer. Allow mounting media to cure fully before sealing the slide inside to avoid any risk of the coverslip adhering to the inner walls.
Are there compatible multi-slide versions of this mailer?
Yes. Caplugs® Evergreen offers the two-slide mailer (240-3072-030) and a multi-slide mailer (240-3074-030) in the same PP natural material and closure style for cases requiring multiple slides in a single shipment.
