Two-Slide Mailers, Polypropylene Copolymer, Blue — 25×75 mm | 50/Bag (240-3072-B80)
These Caplugs® Evergreen two-slide mailers are engineered to protect and transport pairs of standard 25×75 mm laboratory glass slides during postal, courier, and inter-facility shipment. Constructed from Polypropylene Copolymer (PPC) — which combines the chemical resistance of polypropylene with enhanced flexibility and impact resistance — each mailer holds two slides with protective clearance to cushion against mechanical stress and drop impact in transit. Supplied non-sterile in 50/Bag quantities, they are well suited to high-volume anatomic pathology, cytology, and histology programs that routinely mail paired or companion slides.

Applications
- Histology: paired hematoxylin & eosin (H&E) plus special stain slide submission in a single mailer
- Cytology: simultaneous transport of companion or duplicate slides for remote or second-opinion review
- Immunohistochemistry (IHC) and fluorescent slide mailing to reference or consulting labs
- Teleconsultation and remote pathology programs requiring paired slide sets
- Proficiency testing and external quality assurance programs (CAP, CLIA, ISO 15189) where lot-traceability and color-coded identification support chain-of-custody documentation
- Color-coded slide workflow sorting: the blue mailer body enables instant visual identification of slide type, case category, or specimen batch at receipt, reducing misidentification in high-volume pathology operations

Frequently Asked Questions
What slide size fits these mailers?
Each mailer is designed for standard 25 mm × 75 mm laboratory microscope glass slides and holds two slides per mailer with protective clearance for safe transit.
Are these mailers sterile?
No — they are supplied non-sterile, which is appropriate for post-staining or processed slide transport. If your workflow requires sterile packaging, please contact us for alternatives.
Why choose a two-slide mailer over a single-slide format?
The two-slide capacity allows paired slides — such as an H&E and a special stain, or a diagnostic slide with its control — to travel together in one unit, reducing handling steps, minimizing the risk of mismatch, and streamlining intake at the receiving lab.
How does the blue color support laboratory workflow?
Color-coded mailers allow staff to sort incoming shipments by slide type, case category, or specimen batch at a glance. Using blue mailers consistently for a defined slide category reduces misidentification risk in high-volume pathology and cytology operations without requiring additional labeling steps.
