250 mL Wide-Mouth Specimen Containers with White Screw Caps — Polypropylene, Non-Sterile, 36/Bag (240-9250-W3L)
These 250 mL wide-mouth polypropylene specimen containers are precision-molded for clinical urine collection, pediatric specimen collection, and cytology cell suspension workflows. Measuring 90 × 65 mm with a 90 mm wide-mouth opening, they accept direct patient collection and large tissue submission without secondary transfer steps. Supplied unassembled — 36 containers plus 36 white PP screw caps per bag — they are ready for pre-labeling and centralized processing workflows out of the box.

Applications
- Routine urinalysis and urine culture — 250 mL is the minimum collection volume for most standard protocols, making these containers the entry-point format for urine specimen collection
- Pediatric specimen collection and partial-void urine samples requiring a smaller-volume, wide-mouth container
- Cytology cell suspension collection and processing
- Instrument rinsate capture and laboratory waste collection
- Biological specimen transport where leak-resistant screw-cap sealing is required
- Decontamination workflows — containers may be autoclaved at 121°C before disposal
- Pre-labeling and centralized processing — the unassembled format allows barcode or adhesive labels to be applied to container bodies before capping

Quality & Procurement
Made in USA (California), these Caplugs® Evergreen specimen containers are manufactured from virgin, BPA-free, phthalate-free polypropylene. Both the container body and cap are molded from the same PP grade, ensuring compatible thread engagement and dimensional stability across temperature cycles from −20°C to +121°C. The natural translucent container wall allows direct visual assessment of specimen volume and gross morphology throughout the pre-analytical chain. LabSupplies.com is an authorized Caplugs® Evergreen dealer stocking 240-9250-W3L from USA inventory, with tiered pricing available for high-volume institutional, clinical, and grant-funded laboratory accounts.
Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile. For applications requiring sterile collection containers, verify your protocol requirements and source accordingly. The unassembled format does allow containers to be autoclaved at 121°C / 15 psi for decontamination prior to disposal.
Can these containers be autoclaved?
Yes. The polypropylene body and cap are both compatible with standard autoclave conditions at 121°C / 15 psi, making them suitable for decontamination before disposal or for sterilization of equipment rinsates.
Why are the containers supplied unassembled?
The unassembled format — 36 containers and 36 caps packed separately — allows laboratory staff to apply barcode labels or adhesive specimen labels to the container body before capping, which is standard practice in centralized processing and high-throughput collection workflows.
Is 250 mL sufficient for routine urine collection protocols?
Yes for most routine urinalysis and urine culture applications — 250 mL represents the minimum collection volume for the majority of standard protocols. For 24-hour urine collection or larger-volume applications, consider the larger formats in the same Caplugs® Evergreen wide-mouth family (400 mL, 500 mL, or 900 mL), which share the same 90 mm wide-mouth design and white cap color convention.
