HDPE is more rigid than low-density polyethylene and maintains its structural integrity under normal storage and transport conditions. Note that HDPE is not recommended for autoclaving and may be permeated or swelled by certain organic solvents, including halogenated and aromatic compounds; it is best suited for aqueous and mildly aggressive sample types.\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.
