400 mL Wide-Mouth Specimen Containers with White Screw Caps — Polypropylene, 24/Bag (240-9400-W3L)
These 400 mL wide-mouth polypropylene specimen containers are precision-molded from virgin PP and paired with white PP screw caps, supplied unassembled 24 containers + 24 caps per bag for pre-labeling flexibility in centralized processing workflows. The 90 mm wide-mouth opening allows direct patient collection and large tissue or stool specimen submission without secondary transfer, while the natural PP body permits direct visual volume assessment throughout the pre-analytical chain. Measuring 90 × 100 mm (D × H), these containers are autoclave-compatible at 121°C for safe decontamination before disposal and dimensionally stable from −20°C to +121°C.

Quality & Procurement
Made in USA (California), these Caplugs® Evergreen specimen containers are molded from virgin polypropylene under ISO 9001 quality management using FDA-compliant, BPA-free, and phthalate-free resin. Both the container body and cap are manufactured from the same PP grade, ensuring consistent thread engagement and dimensional stability across temperature cycles from deep-freeze storage through autoclave decontamination. LabSupplies.com is an authorized dealer of Caplugs® Evergreen consumables and ships from USA inventory, with tiered pricing available for high-volume institutional and clinical accounts. The 240-9400-W3L is part of a matched wide-mouth collection family that spans 250 mL, 500 mL, and 900 mL volumes — all with white caps — enabling single-vendor procurement across the full collection volume spectrum.
Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile, which is standard for 24-hour urine collection, stool collection, and most bulk specimen workflows that do not require sterile packaging. If your protocol requires sterile containers, please contact us for guidance on available sterile options.
Do the containers come pre-assembled with caps attached?
No — each bag contains 24 containers and 24 caps supplied unassembled. This allows laboratory staff to apply barcode labels or adhesive specimen labels to containers before capping, which is the preferred workflow in many centralized processing and outpatient collection environments.
Can these containers be autoclaved for decontamination before disposal?
Yes — the polypropylene body and cap are both rated for autoclave sterilization at 121°C / 15 psi, making these containers suitable for safe decontamination of biohazardous specimens before disposal in compliance with waste management protocols.
Is a single 400 mL container sufficient for a complete 24-hour urine collection?
For most adult patients, average 24-hour urine output falls within a range that may require more than one container. The 400 mL capacity is appropriate for partial aliquots, pediatric collections, or protocols where the total volume is split across multiple containers. Laboratories routinely issue two containers per patient for standard adult collections.
