Frequently Asked Questions
Are Bitran S Series bags suitable for formalin-preserved specimens?
Yes. The Saranex multilayer barrier film is designed to limit vapor permeation from volatile preservatives such as formalin, making these bags appropriate for long-term storage of fixed specimens.
How are these bags sealed?
Each bag features a sealable zipper-style closure for repeatable, leak-resistant containment without heat sealing or additional equipment.
Which size should I order?
Seven sizes range from 2x4 in for small biopsy specimens to 24x24 in for large gross or pooled samples. Selection depends on specimen volume and required headspace for preservative.
Are these bags sold sterile?
No. Bitran S Series Saranex bags are supplied non-sterile and are intended for storage, archiving, and transport rather than aseptic collection.
