Two-Slide Mailers, Black Polypropylene — 25×75 mm, 50/Bag (240-3072-Z30)
These black polypropylene two-slide mailers are designed to transport and mail two standard 25×75 mm glass microscope slides simultaneously, protecting fragile specimens from breakage, contamination, and moisture damage during postal and courier transit. Supplied non-sterile in bags of 50, part number 240-3072-Z30 is a reliable choice for anatomic pathology, cytology, and histology labs that routinely ship paired slides for remote review, teleconsultation, or proficiency testing. The black body color enables immediate visual identification within multi-color slide-coding systems, distinguishing specific case types or batch groups at a glance.

Frequently Asked Questions
What slide size do these mailers accept?
These mailers are designed for standard 25×75 mm laboratory glass microscope slides, the format used across histology, cytology, hematology, and IHC workflows.
Can I use these mailers to ship slides through the postal service or a courier?
Yes — the rigid polypropylene construction is intended to protect fragile glass slides from breakage and moisture damage during postal and courier transit. Always follow applicable carrier and regulatory guidelines for shipping diagnostic specimens.
Why choose a black mailer instead of a clear or white one?
Black mailers stand out visually within multi-color slide-coding systems, allowing labs to designate specific case types, stain categories, or batch groups by mailer color and identify them instantly on receipt — no labels or extra marking required.
Are these mailers sterile, and are they compatible with CAP/CLIA recordkeeping?
These mailers are non-sterile, which is appropriate for fixed or processed slides that do not require a sterile transport environment. Each bag carries lot numbering to support the traceability documentation required by CAP, CLIA, and ISO 15189 accreditation programs.
