Frequently Asked Questions
What slide size do these mailers accept?
These mailers are designed for standard 25 mm × 75 mm × 1 mm laboratory glass microscope slides — the format used in the vast majority of histology, cytology, hematology, and IHC workflows.
Why choose black mailers over clear or other colors?
Black is commonly assigned within color-coded slide management systems to designate a specific panel type, case priority, organ system, or department. Using a dedicated color at the mailer level reduces misrouting errors from submission through pathologist review, particularly in high-volume or multi-department environments.
Are these mailers compatible with CAP and CLIA traceability requirements?
Yes — each lot is lot-numbered, which supports the specimen traceability documentation required in CAP- and CLIA-accredited laboratories as well as ISO 15189-certified facilities.
Are these slide mailers autoclavable?
Polypropylene is generally autoclavable, but these mailers are supplied non-sterile and are intended for slide transport and mailing rather than sterile processing. Consult your laboratory's SOP before placing any labware in an autoclave cycle.
