Porous metal has been widely used in advanced technology applications and has found a number of uses in the design and manufacture of medical devices. Porous metal is ideal for providing highly dependable filtration performance, controlling fluid flow, as well as diffusion and metering of fluids and drugs. Rigid and robust, porous metal affords designers novel and unique properties that are often the solution for challenging medical and life sciences applications.Porous metal is available in biocompatible materials commonly relied on by the medical industry including stainless steel and titanium. Mott Corporation supplies components in 316L, 304, 310 and 400 series stainless steels, unalloyed titanium (ASTM 1580-07), as well as a number of other common and exotic metallurgies including zirconium, molybdenum, niobium, and precious metals including gold, silver, palladium and others.Mott Corporation adds that it offers an all-metal membrane that meets ASTM F838-05 for bacterial retention. Mott sterilising grade membranes are supplied in 316L stainless steel or titanium. This technology is available in a variety of form factors from very small discs or tubes for drug delivery applications to larger 10 inch cartridges for biotechnology and pharmaceutical processing. This proprietary membrane is able to withstand aggressive chemistries and drug cocktails without the potential for leaching, outgassing, or other adverse reactions. Mott porous metal components are available with filtration ratings from sub-micron (0.1µm) to coarser filtration ratings, including 0.2µm sterilising grade media. Mott also produces specialised gas filters that can achieve 99.9999999% efficiency for particles as small as 0.003µm.Porous metal flow restrictors have been used for decades to meter the flow of critical gases in medical and non-medical applications precisely. Mott Corporation has modeling and calibration capability that enables the calibration of gas flow to accuracies of ±2% at a given inlet and outlet condition. Porous metal can also be designed to permit the controlled diffusion of liquids or gases desirable for certain drug delivery and fluid metering applications.
