Sample Handling 9 n email: export@alphalabs.co.uk MetalFree® centrifuge tubes are ideal for sensitive applications requiring ultra-low levels of common trace metals, with trace metal contents certified below 1 part per billion. Tubes remain functional within temperatures ranging from -80°C to 122°C, so are suitable for autoclaving and freezing. During autoclaving, caps must be loosely attached to tubes. Each tube is 118mm in length, with an internal diameter of 15mm, and an external diameter of 17mm. Tubes are lot tested, certifying them free from ATP, RNase, DNase, and Endotoxin/Pyrogen. A guaranteed sterility assurance level of 10-6 is achieved via gamma radiation, following ISO 11137 validated procedures for sterility. Sterile, MetalFree centrifuge tubes are available racked or loose. Metal free 15ml and 50ml tubes are designed for the centrifugation and storage of samples affected by trace metals. Providing a solution to the increasing awareness surrounding how trace metal presence causes experimental anomalies. These tubes are perfect for ICP-MS procedures, environmental, soil and water analysis. Uniquely manufactured, these tubes are made from 100% virgin ultra-low metal medical grade polypropylene resins, free from Oleamide, diHEMDA and phthalate. Accompanying flat style caps are made from easy to label colorant free polyethylene. A large smudge resistant panel allows the tubes themselves to be labelled for sample identification. Tube walls are thick and durable, withstanding centrifugation forces of up to 20,000g.
