| I just purchased one of your stainless filter holders and after only a few uses it is starting to rust. Is the unit defective? | Rusting of stainless steel holders can usually be attributed to high iron content in the water. Iron deposits create rust "stains" that can be removed with non abrasive cleaners or sometimes fine steel wool. All stainless steel can rust over time. It should be washed with DI water and dried thoroughly immediately after each use. |

应用
适合在入口压力为20至700 bar时对气体或液体进行过滤。压差取决于所使用的滤膜类型。所有换膜过滤器都可高温高压灭菌。换膜过滤器XX44 047 00配用背压支撑网。如果使用了PTFE涂层的支撑网（XX44 047 02 和 XX44 047 04），那么该过滤器可在装有滤膜时高温高压灭菌。过滤器XX45 047 00可配备上游滤膜支撑网（XX45 047 04）以对滤膜进行背压保护。
