Centrifuge Tubes, MetalFree™, Polypropylene, Flat Bottom, Tubes with Flat caps

MetalFree Free-standing Centrifuge Tubes
MetalFree 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 an Inductively Coupled Plasma Mass Spectroscopy (ICP) system these tubes are free of more than 40 common trace metals to a detection level of 1 part per billion (10-9).
