900 mL Wide-Mouth Specimen Containers with White Screw Caps — Polypropylene, 24/Bag (240-9950-W3L)
These 900 mL wide-mouth polypropylene specimen containers are the largest-volume format in the Caplugs® Evergreen screw-cap range, measuring 120 × 138 mm (D × H) and fitted with a white PP screw cap for maximum label contrast with adhesive and barcode labels. Supplied unassembled (24 containers + 24 caps per bag) and non-sterile, they are the container of choice for high-output 24-hour urine protocols, polyuria patients, and bulk specimen archiving where no smaller single container suffices. The natural PP body allows direct visual volume assessment throughout pre-analytical handling, and the 120 mm wide-mouth opening supports direct patient self-collection as well as large gross tissue submission without secondary transfer.

Applications
- 24-hour urine collection for creatinine clearance, total protein, hormones, and heavy metals — particularly suited for polyuria protocols requiring the full 900 mL capacity
- Bulk specimen archiving where a single container must accommodate the complete collection volume
- Gross tissue submission and large biopsy collection, facilitated by the 120 mm wide-mouth opening that eliminates the need for secondary transfer
- Stool specimen collection and other high-volume clinical sample types
- Pre-analytical urine handling with direct visual volume assessment through the natural translucent PP body
- Decontamination before disposal via autoclave at 121°C, supporting laboratory biosafety workflows

Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile and unassembled (24 containers + 24 caps per bag). For workflows that require sterile containers, a separately certified sterile product would be needed; these are appropriate for the vast majority of 24-hour urine and bulk specimen collection protocols where sterility is not required.
Can these containers be autoclaved for decontamination before disposal?
Yes. The polypropylene construction is compatible with standard autoclave cycles at 121°C / 15 psi, making them suitable for biohazardous waste decontamination prior to disposal in accordance with laboratory biosafety protocols.
Why is the white cap beneficial for barcode-based specimen labeling?
White provides the highest contrast background for both printed adhesive labels and direct thermal barcode labels, making it the preferred cap color in LIS-integrated workflows where reliable barcode scanning is critical. Applying specimen labels to the container body before capping is recommended for optimal scanner read rates.
What is the difference between the 750 mL and 900 mL formats, and when should I choose 900 mL?
The 750 mL container (120 × 97 mm) is appropriate for standard 24-hour urine output, while the 900 mL format at 120 × 138 mm is the right choice for polyuria patients or any protocol where total collection volume is expected to exceed 750 mL. At 900 mL, it is the largest single container in the Caplugs® Evergreen wide-mouth range, eliminating the need for multiple containers or mid-collection transfers in high-output cases.
