900 mL Wide-Mouth Specimen Containers with Green Screw Caps — Polypropylene, 24/Bag (240-9950-G3L)
These 900 mL wide-mouth polypropylene specimen containers are the highest-volume format in the Caplugs® Evergreen screw-cap specimen container range, purpose-built for 24-hour urine collection, polyuria protocols, and bulk specimen archiving where a single container must hold the full collection. Each container measures 120 × 138 mm (D × H) with a 120 mm wide-mouth opening and is supplied unassembled — 24 natural-body containers and 24 green PP screw caps per bag — ready for barcode or specimen labeling before capping in LIS-integrated workflows. Part number 240-9950-G3L is autoclave-compatible at 121°C / 15 psi for safe decontamination prior to disposal.

Applications
- 24-hour urine collection for creatinine clearance, urinary protein, hormone panels, and heavy metals — 900 mL is the preferred volume for high-output and polyuria patient protocols
- Stool and gross tissue specimen submission, where the 120 mm wide-mouth opening accommodates direct patient self-collection or large sample transfer without a secondary vessel
- Bulk specimen archiving and long-term frozen storage, supported by dimensional stability from −20°C to +121°C
- Environmental sampling and other test types where green cap color-coding designates a specific specimen category in multi-analyte laboratory workflows
- Pre-analytical volume assessment — the natural translucent PP body allows visual inspection of specimen volume throughout handling without opening the container
Chemical Resistance

| Dilute bases | Excellent |
| Ethanol and isopropanol (<70%) | Good — short-term contact |
| Formalin / formaldehyde | Good — short-term contact; verify for extended fixation |
| Chlorinated solvents (chloroform, methylene chloride) | Not recommended |
| Aromatic solvents (xylene, toluene) | Not recommended |
| Autoclave sterilization (121°C / 15 psi) | Compatible |

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 collection vessels, a sterile-certified product should be selected instead.
Can these containers be autoclaved for decontamination before disposal?
Yes. The polypropylene body and cap are compatible with standard gravity-cycle autoclaving at 121°C / 15 psi, making these containers suitable for biohazardous waste decontamination protocols prior to disposal.
Why does the cap color matter in a clinical lab?
Green is a widely adopted cap color used by many laboratories to designate urine collections, environmental samples, or specific test-type lanes in multi-analyte workflows. Color-coded caps allow bench staff and specimen processors to route containers visually at a glance, reducing misidentification without relying solely on secondary labels.
Is 900 mL the right volume for all 24-hour urine collections?
For most patients, volumes in the 750 mL range are sufficient; the 900 mL format is specifically suited to high-output and polyuria protocols where a standard container may not accommodate the full collection. If your lab handles mixed patient populations, Caplugs® Evergreen offers the same green-cap design in 250 mL, 400 mL, 500 mL, and 750 mL sizes for flexible volume selection within a single procurement program.
