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 )

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) (500 per CS )
