Two-Slide Mailers, 25×75 mm — Polypropylene Copolymer, Red, 50/Bag (240-3072-R80)
These red polypropylene copolymer two-slide mailers are engineered for the safe paired transport and mailing of two standard 25×75 mm laboratory glass slides per mailer, supplied non-sterile in 50/Bag for anatomic pathology, cytology, and histology workflows. Part number 240-3072-R80 combines the chemical resistance and impact-absorbing flexibility of polypropylene copolymer construction with a bold red body that enables immediate color-coded visual identification — ideal for flagging STAT, urgent, or priority cases throughout transit, sorting, and pathologist review.

Applications
- Histology: paired H&E plus special stain slide mailing in a single mailer, reducing packaging overhead versus two separate single-slide mailers
- Cytology: simultaneous transport of two companion cytology slides for a single case
- Immunohistochemistry (IHC): co-transport of diagnostic and companion IHC slides
- Teleconsultation and second-opinion programs: paired slide submission to remote pathologists or reference laboratories
- Proficiency testing: bundled shipment of test and control slides under a single lot-traceable mailer
- Priority and STAT case flagging: red body provides instant visual identification at receipt in high-volume anatomic pathology and cytology labs operating under CAP/CLIA or ISO 15189 programs

Frequently Asked Questions
How many slides does each mailer hold?
Each mailer accommodates two standard 25×75 mm glass slides, making it well suited for paired case submissions such as H&E plus special stain, IHC companion slides, or duplicate slides for teleconsultation.
Why choose red mailers over clear or other colors?
The red body enables immediate color-coded visual identification during transit, sorting, and pathologist receipt — a practical workflow tool for flagging STAT or urgent cases in high-volume labs without additional labeling steps.
Are these mailers compatible with standard microscope slides?
Yes. They are designed for 25 mm × 75 mm × 1 mm standard laboratory glass microscope slides, the format used across histology, cytology, hematology, and IHC applications.
Do these mailers support CAP or CLIA traceability requirements?
Yes. Each bag carries a lot number, which can be documented in laboratory records to satisfy traceability requirements under CAP accreditation, CLIA regulations, and ISO 15189 quality management systems.
