Genizer inlet and outlet check valves are designed to allow fluid to flow through in one direction and avoid back flow. These check valves are made from pharmaceutical-grade material strong enough to handle fluids at pressures up to 40,000 psi, and they can be a full replacement for the original parts within Microfluidizer processors M7125 and M7250. We have been providing high quality spare parts for high pressure homogenization in compliance with FDA standards. Our confidence in the quality of our products allows us to provide a 90-day or 1-year warranty depending on the items.
