One-Slide Mailers, 25×75 mm, Polypropylene Copolymer, Green — Caplugs® Evergreen (240-3071-G80)
These green polypropylene copolymer one-slide mailers are designed to safely transport and mail single standard 25×75 mm laboratory glass slides, with the green body enabling color-coded slide identification and workflow sorting across busy pathology and clinical lab environments. Supplied non-sterile in 50/Bag bulk format, they combine the chemical resistance of polypropylene with enhanced flexibility and impact resistance to protect fragile slides during postal, courier, and interlaboratory transit. Lot-numbered for traceability, these mailers are well suited to anatomic pathology, cytology, histology, and proficiency-testing workflows where safe slide transport and rapid visual identification are both priorities.

Frequently Asked Questions
What slide size do these mailers fit?
The mailer interior is designed for standard 25×75 mm laboratory glass slides — the format used across histology, cytology, hematology, IHC, and most other glass-slide-based workflows.
Why choose green mailers over a plain or white option?
The green body color allows labs to implement color-coded slide management systems, visually distinguishing specific slide types, specimen batches, or case categories at intake and during review sorting — reducing handling errors in high-volume departments without any additional labeling step.
Are these mailers sterile?
No — they are supplied non-sterile, which is appropriate for fixed or stained glass slides used in anatomic pathology, cytology, and histology. Sterility is not required for these applications.
Are the mailers lot-numbered, and does that support accreditation requirements?
Yes — each bag carries a lot number to support reagent and consumable traceability requirements under CAP, CLIA, and ISO 15189 laboratory quality programs.
