50mL MetalFree Centrifuge Tubes, Bulk, 50/bag, 500/cs
MetalFree Centrifuge Tubes
Our 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 20 common trace metals to a detection level of 1 part per billion.
Unmatched Purity
Our MetalFree® tubes are not only free of ultra low levels of trace metals. These tubes are also lot tested and certified free of detectable Nuclease, Endotoxin, and ATP contamination.
MetalFree® tubes are available in 15mL, 50mL and sizes in our Patented fiber racks or in Loose bags. Our MetalFree® tubes are also available in a snap cap 1.5mL microcentrifuge tube. All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 method to a sterility assurance level of 10-6.
Our MetalFree® tubes are made with ultra clean resins for the tube and cap and processed to ensure that common trace metals are kept below an ICP-MS detection level of one part per billion (1ppb). These tubes are perfect for storage of samples and for applications requiring the assurance of low background metals.
