237 mL (8 oz) HDPE Specimen Containers with Press-Close Snap Lids — Natural, 120/Bag (240-5701-06N)
These 237 mL (8 oz) specimen containers are molded from high-density polyethylene (HDPE) and fitted with a press-close snap lid designed for rapid, one-hand operation — making them well suited to high-volume clinical specimen collection programs where throughput matters. The natural HDPE construction allows direct visual assessment of sample volume and appearance, while autoclave compatibility at 121°C supports biohazard decontamination before disposal. Each bag ships unassembled with 120 containers and 120 lids, non-sterile, ready for immediate deployment in clinical, research, or field collection workflows.

Applications
- 24-hour urine collection: Timed urine protocols for creatinine, protein, electrolytes, and heavy metals, where the 237 mL capacity is essential for accurate timed-collection aliquots
- Stool specimen collection: Culture, C. difficile, ova and parasite (O&P), and fecal calprotectin testing — the wide mouth and snap lid support patient self-collection without fine-motor coordination
- Bulk specimen archiving: Pooled or aliquotted specimens requiring −20°C frozen storage
- Clinical liquid waste pre-treatment: HDPE withstands brief chemical disinfectant contact; autoclave compatibility supports biohazard decontamination before disposal
- Environmental and field sampling: Water, soil, and other field collections requiring a durable, autoclavable container
- Veterinary diagnostics: Large-animal urine, stool, and fluid collection where container volume is a limiting factor
- Industrial and food quality labs: Bulk QC sample collection with rapid one-hand lid access

Quality & Procurement
Made in USA, these Caplugs® Evergreen specimen containers are manufactured from BPA-free, phthalate-free HDPE resin under ISO 9001 quality management. LabSupplies.com is an authorized dealer stocking this item in USA inventory, typically enabling same-business-day shipment; volume and institutional pricing is available for clinical labs, hospitals, and research institutions running high-throughput collection programs. Laboratories requiring matched containers across a range of collection volumes can source compatible press-close HDPE containers in 16 oz, 32 oz, 64 oz, and 83 oz formats from the same Caplugs® Evergreen product family.
Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile, unassembled (containers and lids packed separately) in a 120-count bag. If your protocol requires sterile containers, please contact us to discuss alternative options in the Caplugs® Evergreen line.
Can these containers be autoclaved?
Yes. The HDPE construction is compatible with standard autoclave cycles at 121°C / 15 psi, making these containers appropriate for biohazard liquid waste decontamination before disposal or for field decontamination workflows. Note that repeated autoclave cycling may affect lid-snap integrity over time.
Is the press-close snap lid leak-proof for transport?
The press-close design provides a secure snap closure suitable for bench-top and short-distance transport workflows such as 24-hour urine collection and stool specimen handling. It is not rated as a hermetically sealed screw-cap closure; for protocols requiring a certified leak-proof seal during transport, a screw-cap format should be evaluated.
Are larger or smaller sizes available in the same container family?
Yes. The Caplugs® Evergreen press-close HDPE specimen container family includes matched sizes from 16 oz through 83 oz (part numbers 240-5702-06N through 240-5705-06N), allowing procurement teams to standardize on a single container style across all collection volume requirements.
