Technical Narrative
The Caplugs® Evergreen 220-9750-03K is a 750 mL Threaded Wide-Mouth Specimen Container in PP (Natural), packaged 50/Bag. The 750 mL wide-mouth format serves large-volume environmental sampling, bulk food testing, and research specimen collection where 500 mL is insufficient. Large-volume water sampling for particulate and microbiological testing, composite food sampling, and soil and sediment collection for contaminant analysis all benefit from the 750 mL wide-mouth format's capacity and direct wide-bore access.
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: $67.55/Bag, $1.3510/ea at 50/Bag. Size siblings: 220-9250-03K (250 mL PP 72/Bag); 220-9400-03K (400 mL PP 60/Bag); 220-9500-03K (500 mL PP 60/Bag). LabSupplies.com ships from USA inventory, typically same business day.

Clinical & Research Laboratory Applications
Caplugs® Evergreen 750 mL PP threaded wide-mouth specimen containers serve environmental field programs, food safety agencies, and research institutions requiring the largest standard collection volume in the Caplugs Evergreen wide-mouth series. Large-volume water sampling for low-concentration contaminant analysis, low-level microbiological testing, and composite environmental sampling protocols use 750 mL to ensure sufficient sample volume for multiple analytical tests from a single collection event. Food safety composite sampling from large lot sizes uses 750 mL containers for initial bulk collection before subsampling to individual test portions. The wide-mouth opening and PP material provide the practical field collection advantage and chemical resistance needed for diverse environmental matrix types.

Frequently Asked Questions
Are the 750 mL containers sterile?
No. Ships Non-Sterile. For sterility-required applications, use gamma-sterilized containers or aseptic technique.
Is the 750 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.
What is the maximum container size in the Caplugs Evergreen wide-mouth specimen container series?
The 750 mL is the largest in the current wide-mouth series. The next batch starts at 900 mL (220-9950-03K). Contact LabSupplies.com for availability of additional sizes.
