Technical Narrative
The Caplugs® Evergreen 220-9250-03K is a 250 mL Threaded Wide-Mouth Specimen Container in PP (Natural), packaged 72/Bag. The 250 mL wide-mouth format is the entry point to the large specimen container series — suited to environmental water and soil sampling, food testing specimen collection, bulk tissue fixation for multi-biopsy lots, and reagent or media preparation at the 200–250 mL scale. The wide-mouth opening accommodates wide-bore pipettes, sampling scoops, and direct specimen placement without the access limitations of narrow-neck bottles.
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: $50.79/Bag, $0.7054/ea at 72/Bag. Size siblings: 220-9400-03K (400 mL PP 60/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 250 mL PP threaded wide-mouth specimen containers serve environmental testing, food safety, industrial QC, and research laboratories requiring large-volume collection and storage capability above the standard 150 mL specimen container range. Environmental monitoring programs use 250 mL containers for surface water, groundwater, and runoff sampling where the wide mouth enables direct field collection without a funnel and the PP material resists the acid preservatives (HCl, H2SO4) added in the field to preserve analytes. Food safety labs use 250 mL wide-mouth containers for composite food sample collection from bulk commodities. Surgical pathology labs use them for batched multi-specimen formalin fixation where a single large container holds multiple cores or biopsies from the same patient for simultaneous fixation.

Frequently Asked Questions
Are the 250 mL containers sterile?
No. Ships Non-Sterile. For sterility-required applications, use gamma-sterilized containers or aseptic technique.
Is the 250 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.
How does this container differ from the smaller 150 mL threaded specimen container (220-5625-03K)?
The 250 mL wide-mouth container is designed for environmental and bulk collection workflows, while the 150 mL container (220-5625-03K) serves surgical pathology and clinical specimen fixation. Both are PP with threaded closures, but the has a wider mouth diameter optimized for field sampling access and the 220-5625-03K has a taller, narrower profile suited to pathology grossing stations.
