Manufactured using high-purity polypropylene, these centrifuge tubes 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) of 18 major groups of metals. The metals included in testing are Zinc, Boron, Iron, Copper, Manganese, Aluminum, Silicon, Nickel, Vanadium, Phosphorous, Cobalt, Chromium, Lithium, Selenium, Cadmium, Mercury, Arsenic, and Lead. The tubes feature printed graduations for easy measuring, a large white marking spot for quick labeling of samples, and leakproof threaded caps that are also free of added colorings and trace metals.
