Molded from polypropylene copolymer (PPC) and color-coded green for easy identification, they are supplied non-sterile in convenient 50\/Bag quantities suited to high-throughput laboratory and environmental sampling workflows. Part number 300-9120-G3K is an ideal replacement or bulk-supply cap for labs that process wide-mouth containers routinely.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003e300-9120-G3K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eWide-Mouth Specimen Container Screw Cap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene Copolymer (PPC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eGreen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eNon-Sterile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Size\u003c\/td\u003e\n\u003ctd\u003e50\/Bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRecapping or replacing caps on wide-mouth specimen collection containers\u003c\/li\u003e\n\u003cli\u003eColor-coded closure management across multiple container types or sample groups\u003c\/li\u003e\n\u003cli\u003eEnvironmental and field sampling where large-volume, wide-mouth vessels are used\u003c\/li\u003e\n\u003cli\u003eBulk specimen storage in clinical, research, or industrial laboratory settings\u003c\/li\u003e\n\u003cli\u003eSecondary containment and transport of large-volume liquid or solid specimens\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMaterial \u0026amp; Chemical Resistance\u003c\/h2\u003e\n\u003cp\u003ePolypropylene copolymer (PPC) offers excellent resistance to aqueous buffers, dilute acids and bases, and many common alcohols, making it well suited to a broad range of laboratory specimens and cleaning reagents. PPC can be autoclaved, supporting reuse in sterile workflows when sterilization is required. As with all polypropylene-based materials, prolonged contact with chlorinated solvents, aromatic hydrocarbons, or concentrated oxidizing acids should be avoided.\u003c\/p\u003e\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, Caplugs® Evergreen specimen container caps are produced under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin.
