Total-Pure™ Centrifuge Tubes are produced from a proprietary purified polypropylene that is certified to be free of trace metal content. Tested via ICP-MS, these tubes are certified to contain less than 1ppm of common trace metals including: Calcium, Magnesium, Zinc, Iron, Manganese, Copper, Aluminum, Silicon, Nickel, Vanadium, Sodium, Phosphorous, Cobalt, Chromium, Potassium, Lithium, Lead, Selenium, Cadmium, Mercury, and Arsenic. In addition to a superior level of purity, TotalPure™ Tubes include a wide array of premium features. These tubes are engineered to withstand a max centrifugation rate of 20,000xg, with this RCF specification printed directly on both the 15mL and 50mL tubes. These tubes also feature Hi-Viz™ graduations that are easily identified at any angle and the printed max-freeze line indicates the maximum allowable volume to be frozen inside the tubes. TotalPure's natural color caps offer a smooth seal that is easy to open/close with one hand without compromising the integrity of the 95kPA leak-proof seal. • Ultra-Pure Polypropylene Certified Free of Trace Metals • Hi-Viz™ Graduations with Maximum Freeze Capacity Line • Resealable Zip Bags of 25 Tubes, or Individually Wrapped • E-Beam Sterilized (SAL 10-6) (250 per CS )
