Supplied non-sterile in bulk (400\/Bag), the red color supports quick visual identification and color-coded workflow management across high-throughput collection environments. Part number 300-5603-R2K is well suited for clinical, environmental, and research laboratories that process large volumes of capped specimen containers.\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\u003e300-5603-R2K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Container Volume\u003c\/td\u003e\n\u003ctd\u003e60 mL \/ 90 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClosure Style\u003c\/td\u003e\n\u003ctd\u003eScrew Cap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Density Polyethylene (HDPE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eRed\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\u003e400\/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 closures on 60 mL and 90 mL specimen containers during collection workflows\u003c\/li\u003e\n\u003cli\u003eColor-coded specimen management to distinguish sample types, collection points, or processing batches\u003c\/li\u003e\n\u003cli\u003eSecuring liquid specimens during transport between collection sites and the laboratory\u003c\/li\u003e\n\u003cli\u003eBulk cap replenishment for high-volume clinical, environmental, or industrial testing labs\u003c\/li\u003e\n\u003cli\u003eGeneral laboratory container closure where a threaded, leak-resistant seal is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMaterial \u0026amp; Chemical Resistance\u003c\/h2\u003e\n\u003cp\u003eHigh-density polyethylene offers broad resistance to aqueous solutions, dilute acids and bases, and many common laboratory reagents, making it a reliable choice for specimen containment. HDPE is more rigid than low-density polyethylene and maintains its dimensional stability under typical ambient storage and transport conditions. Note that HDPE is not recommended for autoclaving; for applications requiring sterilization, select an autoclavable closure material such as polypropylene.\u003c\/p\u003e\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, Caplugs® Evergreen specimen container caps are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin.
