    FAQ

    QuestionAnswer
    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.

    The In-Line Stainless Steel Filter Holders are designed for filtration of gases or liquids at inlet pressures of 20 to 700 bar. Differential pressure depends on the filter type used. All filter holders may be autoclaved. The 47 mm In-Line filter holder (cat. no. XX4404700) is equipped with a back-pressure support screen. It may be autoclaved with filter in place, as long as the optional PTFE-coated support screens (cat. no. XX4404702 and XX4404704) are used. The 47 mm High-Pressure filter holder (cat. no. XX4504700) may be equipped with the upstream filter support screen (cat. no. XX4504704) for back-pressure protection of filter.

    Features & Benefits
