Manufactured using high-purity, virgin USP Class VI Medical grade polypropylene, these centrifuge tubes are free from natural rubber and heavy metal and conform to US FDA 21 CFR. Include leak-proof threaded HDPE caps that are free of added colorings and trace metals. A large, white marking spot allows you to easily label samples. MaxiRCF™ Trace Metal-Free Centrifuge Tubes with 20,000 x g maximum RCF work well for any high-density gradient separation. They are specifically manufactured to ensure that common trace metals and elements that can interfere with experiments are below an ICP-MS detection level of one part per billion (< 1ppb). Metals included in testing are: Zinc, Boron, Iron, Copper, Manganese, Aluminum, Silicon, Nickel, Vanadium, Phosphorous, Cobalt, Chromium, Lithium, Selenium, Cadmium, Mercury, Arsenic and Lead. Available in sterile and non-sterile versions. Sterile versions are validated according to ISO 11137 for SAL 10-6 and packed 25 tubes per sealed bag, 20 bags per case of 500. Non-sterile versions are bulk-packed as a case of 500 tubes. (500 per PK )

Acetic Anhydride, Reagent, ACS, or ethanoic anhydride as it is otherwise known is a colorless, strong smelling liquid chemical compound that is the simplest isolatable acid anhydride and commonly used as a reagent for organic synthesis. Mainly used for acetylations, its main use is for the conversion of cellulose to cellulose acetate and in the synthesis of aspirin. As an ACS grade Reagent, Spectrum Chemical manufactured acetic anhydride is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and pureness.
