Preventing Ferrous Contamination

摘要

Ask yourself this question: At what point in the manufacturing of FDA-regulated products would you use the same equipment that your auto mechanic does to work on your car? According to Steritool Inc., Jacksonville, Fla., even when sterilized before use, ordinary chrome-plated carbon steel hand tools still can contribute to process contamination. A sterilized carbon steel tool is still a ferrous tool, and when used against stainless steel fasteners, for example, it transfers the tool's exposed iron particles to the surface of the stainless. In an oxygen guide, downloadable for free from a maker of rubber products. Information in the 10-page "Rubber Polymer & Material Selection Guide" includes technical details on more than 15 categories of rubber polymers and materials. Material specifications include hardness, temperature ranges performance advantages and limitations. Also addressed is rubber's ability to bond to many substrates, eliminate parts and lower assembly costs.The guide allows users to create a short list of potential polymers for their applications.
