Technical Narrative
The Caplugs® Evergreen 220-9400-03K is a 400 mL Threaded Wide-Mouth Specimen Container in PP (Natural), packaged 60/Bag. The 400 mL wide-mouth format serves environmental sampling agencies, food and water testing laboratories, and research institutions requiring specimen collection at the 300–400 mL scale. Environmental protocols for water, sediment, and food matrix sampling frequently specify 400–500 mL containers for regulatory compliance sampling volumes. The wide-mouth opening allows direct dip-and-fill water sampling without a transfer vessel.
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: $55.82/Bag, $0.9303/ea at 60/Bag. Size siblings: 220-9250-03K (250 mL PP 72/Bag); 220-9500-03K (500 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 400 mL PP threaded wide-mouth specimen containers serve environmental regulatory testing, food safety, and industrial QC laboratories. Many EPA, ASTM, and ISO water quality test methods specify collection volumes in the 250–500 mL range — the 400 mL container satisfies these requirements with overhead capacity for field preservation reagent addition. Environmental sampling programs for metals, organics, microbiological parameters, and nutrient analysis commonly use 400 mL wide-mouth PP containers as the field collection vessel before subsampling to analytical tubes. The wide-mouth opening enables direct dip-and-fill field water sampling and accommodates sampling scoops for sediment collection.

Frequently Asked Questions
Are the 400 mL containers sterile?
No. Ships Non-Sterile. For sterility-required applications, use gamma-sterilized containers or aseptic technique.
Is the 400 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.
Does the 400 mL container comply with EPA water sampling container requirements?
PP containers comply with EPA method material requirements for containers used with acid and preservative-treated water samples. Verify that your specific EPA method (e.g., EPA 200.7, 300.0, 524.2) specifies PP or plastic as an acceptable container material, as some organic methods require glass. PP is the standard for inorganic and nutrient parameters; glass is required for volatile organics.
