| 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Why are there two stainless steel screens required under the membrane filter of the 47mm ss filter Holder XX4404700? | The photo-etched support (catalog number XX4204709) is used to support the membrane during filtration. The underdrain (catalog number 5614) is used to lift the downstream side of the membrane away from the bottom plate so that better flow is achieved. |
