PPC is autoclavable, supporting heat-sterilization of caps when process requirements demand it. As with all polypropylene-based materials, prolonged contact with chlorinated solvents, aromatic hydrocarbons, and concentrated oxidizing acids should be avoided.\u003c\/p\u003e\n\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.
