Frequently Asked Questions
Are these specimen containers sterile?
No — the containers are supplied non-sterile, which is appropriate for most routine pathology, histology, and research specimen collection workflows where sterility is not required. If your protocol requires sterile containers, please contact our team for guidance on alternative options.
Why are the containers supplied unassembled?
The unassembled format allows laboratory staff to assemble containers as needed, reducing the risk of cap contamination or loosening during bulk storage and transport. It also provides flexibility for labs that prefer to pre-label bodies before attaching caps.
Are these containers compatible with standard specimen transport protocols and barcode labeling?
Yes — the smooth polypropylene body accepts printed labels and barcode stickers reliably, and the secure screw-cap closure is compatible with standard clinical specimen transport protocols. Lot numbers on every bag support traceability documentation for CAP- and CLIA-accredited laboratories.
Can these containers hold formalin or other fixatives?
Polypropylene provides good resistance to neutral buffered formalin and similar aqueous fixatives used in routine histology and pathology workflows. Strong organic solvents such as acetone or chloroform are not recommended for use with these containers.
