Our MetalFree™ centrifuge tubes are produced to ensure that key trace metals are kept below one part per billion (1ppb). They can be used for storage and analysis tasks that require extremely low levels of most common metals. These tubes are produced with a proprietary process that virtually eliminates common metals. Far cleaner than metal free tubes offering a simple 1 part per million (1ppm) certification these tubes are unique. Developed in our own lab and using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) these tubes are free of more than 20 common trace metals to a detection level of 1 part per billion.
