HDPE is a rigid, durable thermoplastic; however, it is not recommended for autoclave sterilization and may be susceptible to swelling or permeation with certain aromatic and chlorinated solvents at elevated concentrations. For aqueous biological and environmental specimens, HDPE provides dependable performance.\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 HDPE resin.
