946 mL (32 oz) HDPE Specimen Containers with Press-Close Snap Lids — Natural, 84/Bag (240-5703-06N)
These 946 mL (32 oz) specimen containers are molded from High-Density Polyethylene (HDPE) and fitted with press-close snap lids designed for rapid one-hand operation — an important advantage in high-throughput clinical collection workflows and patient self-collection settings. Supplied unassembled (84 containers + 84 lids per bag), the natural HDPE construction allows direct visual assessment of specimen volume and color without opening the container. Part number 240-5703-06N is autoclave-compatible at 121°C and non-sterile as shipped.

Applications
- 24-hour urine collection: Timed urine protocols for creatinine clearance, urinary protein, heavy metals, and hormone panels — the 946 mL volume is essential for accurate single-container timed collections
- Large-volume void urine: Bulk void specimen collection where smaller containers require inconvenient multi-container splits
- Stool specimen collection: C. difficile, culture, ova and parasite, and fecal calprotectin testing — the wide mouth and press-close lid support patient self-collection without fine-motor coordination
- Clinical liquid waste pre-treatment: HDPE withstands brief contact with chemical disinfectants before autoclaved biohazard disposal
- Bulk specimen archiving: Pooled specimens and aliquot source material — HDPE is suitable for −20°C frozen bulk storage
- Environmental and field sampling: Water, soil, and field-collected samples where autoclave decontamination before disposal is required
- Veterinary diagnostics: Large-animal urine, stool, and fluid collection where volume range is well matched
- Industrial and food laboratory QC: Bulk quality-control sample collection benefiting from rapid one-hand press-close operation

Frequently Asked Questions
Are these containers sterile?
No — they are supplied non-sterile in 84/Bag packaging. For workflows that require a sterile collection vessel, a separately sterilized container or a sterile-packaged product should be used. Non-sterile containers are appropriate for 24-hour urine, stool, waste, environmental, and industrial applications where pre-use sterilization is not required.
Can these containers be autoclaved for biohazard decontamination before disposal?
Yes. HDPE is autoclave-compatible at 121°C / 15 psi, making these containers suitable for standard gravity or pre-vacuum biohazard decontamination cycles before disposal. Autoclave compatibility is intended for decontamination, not repeated sterilization cycles for reuse.
How does the press-close lid compare to a screw-cap container for 24-hour urine collection?
The press-close snap lid allows one-hand opening and closing without thread engagement, which is particularly valuable for patient self-collection and for clinical staff processing containers at volume. Screw caps provide a more hermetic seal for shipping or transport protocols requiring leak certification; for benchtop collection and clinical processing workflows, the press-close format offers meaningful speed and ease-of-use advantages.
Are other sizes available in the same container family?
Yes. The Caplugs® Evergreen press-close HDPE specimen container line includes an 8 oz natural container (240-5701-06N), a 16 oz natural container (240-5702-06N), a 64 oz natural container (240-5704-06N), and an 83 oz natural container (240-5705-06N), allowing standardized procurement across a full range of collection volumes.
