Static Homogenizing Valve Avestin has developed a static valve to be used for high pressure homogenization. These static valves use collision and high shear to generate pressures up to 2000bar/30000psi. An Avestin static valve can be fully disassembled for cleaning, inspection and validation. This technology is ideal for emulsions, and can be used for cell rupture, nanoparticles and liposomes. These static valves may be used as a replacement for the chambers used on several manufacturers’ homogenizers.
