900 mL Wide-Mouth Threaded Specimen Containers — Polypropylene, Natural, 24/Bag (220-9950-03K)
These 900 mL wide-mouth specimen containers are precision-molded from virgin polypropylene (PP) and sealed with a threaded screw cap for leak-free specimen transport and storage. At 120 × 138 mm (D × H), the wide-mouth opening accommodates direct patient collection and large biopsy or surgical specimen submission without a secondary transfer step, reducing contamination risk and pre-analytical handling errors. Supplied non-sterile in a convenient 24/Bag format, they are well suited for high-volume clinical, pathology, microbiology, environmental, and biorepository workflows.

Applications
- Clinical specimen collection: Urine, stool, sputum, and wound swab media — the 120 mm opening allows direct patient collection without secondary transfer, preserving sample integrity and reducing contamination risk.
- Pathology & histology: Gross tissue and large biopsy or surgical specimen submission, where the wide mouth eliminates the need to cut or compress specimens during accessioning.
- Microbiology: Primary specimen storage and culture media; PP construction is compatible with fixative pre-rinsing and standard transport media.
- Environmental sampling: Water, soil, and sediment collection in the field — the threaded screw cap provides a positive, leak-resistant seal during transport.
- Biorepository & bulk aliquot archiving: Stackable footprint supports efficient freezer shelf utilization for long-term specimen archiving.
- Industrial & food QC labs: Bulk sample collection and quality-control sampling workflows that require autoclavable, chemically resistant containers.

Frequently Asked Questions
Are these containers sterile?
No — they are supplied non-sterile. If your workflow requires sterile containers, they should be sterilized prior to use. The PP construction is autoclave-compatible at 121°C / 15 psi, making in-house sterilization straightforward.
Can these containers be used to fix tissue in formalin?
PP is compatible with brief formalin exposure, making these containers suitable for workflows where tissue specimens are collected and then transferred to a fixative. Prolonged formalin storage in PP is not recommended; consult your pathology SOP for designated formalin-compatible containers if extended fixation is required.
Will the screw cap provide a leak-free seal for transport of infectious specimens?
The threaded screw cap is designed to provide a positive, leak-resistant seal suitable for standard specimen transport. Laboratories shipping specimens as infectious substances should verify that their complete packaging system meets applicable regulatory requirements (e.g., IATA P650, DOT).
Are other sizes available in the same container family?
Yes — Caplugs® Evergreen offers matched wide-mouth PP specimen containers in 250 mL, 400 mL, 500 mL, and 750 mL formats, allowing procurement of a single container platform across multiple volume needs with consistent cap threading and container geometry.
