Two-Slide Mailers, Polypropylene Copolymer, Yellow — Caplugs® Evergreen (240-3072-Y80), 50/Bag
These yellow polypropylene copolymer (PPC) two-slide mailers are designed for the paired transport and mailing of two standard 25 × 75 mm laboratory glass slides per unit, supplied non-sterile in a convenient 50/Bag format. The PPC construction combines the chemical resistance of polypropylene with enhanced flexibility and impact resistance, protecting fragile glass slides from breakage during postal or courier transit. Yellow body color provides instant color-coded identification for workflow sorting in anatomic pathology, cytology, and histology departments.

Applications
- Histology: paired H&E and special stain slide submission in a single mailer
- Cytology: simultaneous transport of two companion diagnostic slides
- Immunohistochemistry (IHC): co-mailing of primary and companion IHC slides
- Fluorescent slide transport: protected paired mailing for fluorescence-labeled preparations
- Teleconsultation and remote second-opinion programs: paired diagnostic slide sets mailed together to reduce packaging cost
- Proficiency testing and external quality assurance programs requiring duplicate slide submission
- Color-coded slide management systems: yellow mailers distinguish specific case categories or batch groups at receipt and sorting
- CAP/CLIA and ISO 15189 laboratories requiring lot-traceable slide transport consumables

Frequently Asked Questions
How many slides do these mailers hold?
Each mailer accommodates two standard 25 × 75 mm laboratory glass microscope slides, making them well suited for paired-slide submissions such as H&E plus special stain, IHC companion slides, or duplicate teleconsultation sets.
Are these slide mailers sterile?
No — they are supplied non-sterile, which is standard for anatomic pathology and histology slide transport applications where sterility is not required.
Why choose yellow mailers instead of a clear or neutral color?
The yellow body color supports color-coded workflow management, allowing staff to distinguish specific slide types, case categories, or priority batches at a glance during receipt, sorting, and accessioning — reducing handling errors in busy pathology departments.
Are these mailers compatible with standard postal and courier shipping?
Yes — the polypropylene copolymer construction provides enhanced flexibility and impact resistance compared to standard PP, helping protect fragile glass slides from breakage under the mechanical stresses of postal and courier transport. Always follow applicable regulations for shipping biological or diagnostic specimens.
