500 mL Wide-Mouth Specimen Containers with Screw Caps — Polypropylene, Natural, 60/Bag (220-9500-03K)
These 500 mL polypropylene specimen containers feature a threaded wide-mouth neck and screw cap, making them the workhorse choice for regulatory environmental sampling, water and food matrix testing, and bulk media preparation. Supplied non-sterile in 60/Bag packaging, they deliver the exact 500 mL collection volume cited in many EPA and FDA method specifications for water, sediment, and food matrix work. The natural PP construction provides broad chemical compatibility with organic preservatives, acid preservatives, and aqueous reagents across a wide pH range.

Applications
- Regulatory water sampling following EPA and FDA methods that specify 500 mL as the standard or minimum collection volume
- Microbiological water testing per AOAC/APHA methods — PP is compatible with sodium thiosulfate and other dechlorinating agents used in potable water collection
- Sediment and soil sampling for RCRA and CERCLA environmental investigations requiring a discrete 500 mL sample volume
- Composite food sampling and food safety testing where the wide-mouth opening allows direct transfer of solid or semi-solid food matrices
- Bulk media and reagent preparation in microbiology and chemistry labs, including acid digestion buffers
- Secure sample storage on the shelf or under refrigeration, with the threaded screw cap providing a reliable seal
- Process and QC sampling of viscous or particulate-laden samples in pharmaceutical and industrial settings

Quality & Procurement
Made in USA, these Caplugs® Evergreen specimen containers are produced from FDA-compliant, BPA-free, phthalate-free, and latex-free polypropylene resin under ISO 9001 quality management. LabSupplies.com is an authorized dealer and ships from USA inventory, typically the same business day for stocking items. For laboratories with recurring sampling programs or high-volume procurement needs, tiered pricing is available — contact our team for institutional and grant-funded account options. Labs requiring adjacent volumes can also source the 250 mL (220-9250-03K), 400 mL (220-9400-03K), and 750 mL (220-9750-03K) PP wide-mouth containers from the same product family.
Frequently Asked Questions
Are these specimen containers sterile?
No — they are supplied non-sterile. For microbiological water testing requiring sterile containers, pre-sterilized alternatives should be used; however, these containers are well suited for environmental chemistry, sediment, and food matrix sampling workflows where sterility is not required.
Are these containers compatible with acid and formalin preservatives used in environmental sampling?
Yes. Polypropylene offers excellent resistance to formaldehyde/formalin, dilute hydrochloric acid, dilute sulfuric acid, and other common field preservatives, making these containers appropriate for EPA and FDA regulated environmental and water sampling protocols.
Can the containers be used in a water bath or warmed reagent protocol?
The polypropylene construction is rated to approximately 80°C, making these containers suitable for warmed reagent and media preparation applications within that temperature range. They are not intended for autoclaving.
What other sizes are available in this same container family?
The Caplugs® Evergreen wide-mouth PP specimen container line includes a 250 mL version (220-9250-03K, 72/Bag), a 400 mL version (220-9400-03K, 60/Bag), and a 750 mL version (220-9750-03K, 50/Bag), all in the same natural PP construction with threaded screw caps.
