One-Slide Mailers — Polypropylene Copolymer, Red, 25×75 mm, 50/Bag (240-3071-R80)
These red polypropylene copolymer one-slide mailers are engineered to protect a single standard 25×75 mm laboratory glass slide during postal, courier, and interlaboratory transport. Supplied non-sterile in 50/Bag bulk packaging, the red body color enables immediate color-coded identification for STAT, priority, or specialty slide workflows in anatomic pathology, cytology, and clinical laboratory departments. The PPC construction delivers enhanced flexibility and impact resistance compared to standard polypropylene, reducing the risk of slide breakage in transit.

Applications
- Postal and courier transport of single 25×75 mm glass slides between laboratories, clinics, and reference centers
- Teleconsultation and second-opinion pathology case submission requiring slide-level protection and identification
- STAT and priority case routing in anatomic pathology — red color provides immediate visual triage at the bench and accessioning station
- Histology and H&E slide transport for routine surgical pathology cases
- Cytology slide mailing for Pap test and FNA specimen review
- Immunohistochemistry (IHC) and fluorescent stain slide transport where physical protection is critical
- Hematology, microbiology, and special stain slide interlaboratory transfer
- Proficiency testing and CAP/CLIA slide submission programs requiring lot-traceable packaging
- Color-coded slide management systems that assign mailer color by case type, department, or urgency tier

Frequently Asked Questions
What slide size do these mailers fit?
These mailers are designed for standard 25×75 mm laboratory glass slides. Always confirm your slide dimensions before ordering if you use non-standard formats.
Why choose red mailers instead of a clear or neutral color?
Red is commonly assigned in color-coded slide management systems to designate STAT, rush, or priority cases, allowing accessioning staff and pathologists to identify urgent material immediately without reading labels. Departments can also use red to denote a specific specimen type, stain category, or referring location according to their own workflow conventions.
Are these mailers suitable for mailing slides through the postal service or courier networks?
Yes — the polypropylene copolymer construction provides enhanced flexibility and impact resistance compared to rigid plastics, helping protect fragile glass slides from breakage during postal and courier transit. Users should follow all applicable carrier regulations and institutional policies for shipping biological specimens or patient materials.
Are the mailers lot-numbered for traceability purposes?
Yes — each bag of 50 mailers carries a lot number, supporting traceability documentation for CAP-accredited, CLIA-certified, and ISO 15189 laboratories that require consumable lot records in their quality management systems.
