Frequently Asked Questions
How many slides do these mailers hold, and what slide format do they accept?
Each mailer holds five standard 25×75 mm glass slides — the format used for virtually all histology, cytology, hematology, and IHC preparations in clinical and research laboratories.
Are these slide mailers sterile?
No — they are supplied non-sterile, which is appropriate for transporting fixed, stained, or processed glass slides in anatomic pathology, cytology, and clinical laboratory settings.
Why would I choose blue mailers specifically?
The blue body color allows laboratories to build a color-coded mailer system in which each color designates a panel type, organ system, case priority, or receiving department. At high volume, this visual sorting system reduces misrouting and speeds receipt processing without requiring labels or written notation on the mailer itself.
Yes — the mailers are, and the BPA-free, phthalate-free polypropylene construction is consistent. Lot information is available for documentation upon request through LabSupplies.com.
