PPC is autoclavable, allowing caps to be heat-sterilized when downstream workflows require it, even though they are supplied non-sterile. As with all polypropylene-family 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 screw caps are produced under ISO 9001 quality management from BPA-free, phthalate-free, latex-free polypropylene copolymer resin.
