Technical Narrative

The Caplugs® Evergreen 220-9500-03K is a 500 mL Threaded Wide-Mouth Specimen Container in PP (Natural), packaged 60/Bag. The 500 mL wide-mouth format is the standard regulatory sampling volume for many environmental and food testing protocols — ASTM, EPA, and FDA method specifications frequently cite 500 mL as the minimum or standard collection volume for water, sediment, and food matrix testing. The wide-mouth opening and PP material combination provides the access and chemical resistance required for field sampling with organic preservatives and acidic reagents.

Polypropylene (PP): full organic solvent and preservative compatibility (formalin, HCl, H2SO4 preservatives), pH 2–12 resistance, ~80°C thermal rating for warmed reagent protocols. The wide-mouth threaded opening provides greater sample access than narrow-neck bottles and accepts a wide range of cap accessories. BPA-free, phthalate-free, FDA-compliant,

Procurement economics: $108.58/Bag, $1.8096/ea at 60/Bag. Size siblings: 220-9250-03K (250 mL PP 72/Bag); 220-9400-03K (400 mL PP 60/Bag); 220-9750-03K (750 mL PP 50/Bag). LabSupplies.com ships from USA inventory, typically same business day.

Clinical & Research Laboratory Applications

Caplugs® Evergreen 500 mL PP threaded wide-mouth specimen containers serve environmental regulatory compliance laboratories as the standard field sampling vessel for water, sediment, and food matrix regulatory programs. The 500 mL volume is specified in EPA 300.0 (ion chromatography), EPA 200-series metals methods, EPA 500-series organic methods, and FDA Bacteriological Analytical Manual methods for the minimum field collection volume. State environmental programs and certified drinking water laboratories standardize on 500 mL PP wide-mouth containers for compliance sampling submitted to state-certified labs. PP's full compatibility with sodium thiosulfate (for microbiological samples) and acid preservatives (for metals and organics) allows field preservation in the collection container without container change.

Frequently Asked Questions

Are the 500 mL containers sterile?

No. Ships Non-Sterile. For sterility-required applications, use gamma-sterilized containers or aseptic technique.

Is the 500 mL PP container compatible with acid preservatives used in environmental sampling?

Yes. PP is fully compatible with standard field preservation reagents including hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3) at ≤10% concentration, and sodium thiosulfate for microbiological dechlorination. These are the primary preservatives specified in EPA, ASTM, and ISO water quality methods for metals, organics, nutrients, and microbiological parameters. PP's broad acid resistance makes it the standard material for field-preserved environmental samples.

Is the 500 mL container compliant with EPA and FDA sampling method container requirements?

PP 500 mL containers comply with EPA and FDA container material requirements for inorganic parameters, nutrients, and microbiological testing. For volatile organic compound (VOC) analysis, EPA methods specify glass VOA vials — PP is not suitable for VOC samples. Verify your specific method container requirement before standardizing.
