473 mL (16 oz) HDPE Specimen Containers with Press-Close Snap Lids — Natural, 120/Bag (240-5702-06N)
These 473 mL (16 oz) specimen containers are molded from High-Density Polyethylene (HDPE) and fitted with a press-close snap lid designed for rapid one-hand operation — eliminating the threading time of screw-cap formats and lowering the fine-motor coordination barrier for patient self-collection. Supplied non-sterile and unassembled (120 containers + 120 lids per Bag), the natural HDPE construction provides excellent chemical resistance, autoclave compatibility at 121°C for biohazard decontamination, and −20°C frozen storage suitability for bulk specimen archiving. The 16 oz volume makes these containers the standard choice for 24-hour urine collection and large-volume void urine protocols where smaller containers require multi-container collection runs.

Applications
- 24-hour urine collection: Timed urine specimens for creatinine clearance, total protein, heavy metals, and other analytes requiring full-day collection volumes
- Large-volume void urine: Bulk void collections where smaller containers would require multiple-container protocols
- Stool specimen collection: Culture, C. difficile, ova and parasite, and calprotectin testing — the wide mouth and press-close lid support patient self-collection without fine-motor demands
- Clinical liquid waste pre-treatment: Collection and brief chemical disinfectant contact prior to disposal; HDPE withstands bleach and common decontaminants
- Bulk specimen archiving: Pooled specimens and aliquot staging with HDPE's −20°C frozen-storage compatibility
- Environmental and field sampling: Water, soil, and field matrices — autoclave compatibility supports field decontamination workflows
- Industrial and food-safety QC: Rapid bulk sample collection where one-hand lid operation speeds throughput
- Veterinary diagnostics: Large-animal urine, stool, and fluid collection requiring high-volume containers

Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile and unassembled (120 containers + 120 lids per Bag). For collections where sterility is required, review sterile-packaged formats within the Caplugs® Evergreen specimen container line.
Can these containers be autoclaved for biohazard decontamination before disposal?
Yes. The HDPE construction is compatible with standard gravity-cycle autoclaving at 121°C and 15 psi, making these containers appropriate for regulated biohazard decontamination workflows prior to disposal. Autoclave compatibility is intended for decontamination, not for sterilizing containers before use.
Why is a press-close snap lid preferred over a screw cap for 24-hour urine collection?
A press-close lid requires only downward pressure to seal and a single lifting motion to open, removing the need for the rotational fine-motor coordination that screw caps demand. This simplifies patient self-collection — particularly for elderly or mobility-limited patients — and also reduces per-container handling time when clinical staff are processing specimens at volume.
Are other sizes available in the same HDPE natural press-close format?
Yes. Related sizes in the same family include the 240-5701-06N (8 oz), 240-5703-06N (32 oz), 240-5704-06N (64 oz), and 240-5705-06N (83 oz), allowing standardized procurement across the full range of collection volume requirements.
