This translucent, semi-rigid (58, Shore D) tubing resists most known chemicals at room temperature and offers high temperature resistance. NALGENE 890 FEP tubing is rated excellent for: acids " dilute, weak, strong or concentrated; aliphatic alcohols, aldehydes, bases, esters, hydrocarbons " aliphatic, aromatic and halogenated; ketones and strong oxidizing agents. NALGENE 890 FEP tubing is used for demanding lab applications such as: chromatography, trace metal analysis, pollution sampling, highly reactive catalyst procedures, metallurgical corrosion testing, pharmaceutical work, dissolutions and hot acid etchings. Superior non-stick characteristics are useful in transferring biological preparations where protein binding/adsorption is a problem. Also eases movement of viscous, aggressive compounds. For high-purity analysis, can be rigorously cleaned in boiling nitric acid. Non-cytotoxic and non-contaminating for critical high-purity work. Resin complies with 21 CFR 177.1550 for food contact. For low pressure use with mechanical, compression-type fittings. Can be sterilized by autoclaving, gas, dry heat and disinfectants. Do not radiation-sterilize. NOTE: Should not be used with molten alkali metals, elemental fluorine and fluorine precursors at elevated temperatures or concentrated perchloric acid.
