Syringe Filters and Filter Plates

 
Syringe Filters

Our syringe filters are ultrasonic welded and certified DIN EN ISO 9001:2000. Not every filter is suitable for every application. In order to give you a rough overview of the application possibilities of our filters, we have put together an overview, by means of which you can make a preliminary selection of the membrane type contained in the filter.
Quality assurance: In order to comply with the highest demands with respect to the quality of our products, various standards are incorporated into our planning and production process.
The high-quality membranes are stored under the controlled conditions of the clean-room at constant air humidity in special containers, and stamped out and further processed from the roll material immediately before final assembly, in order to ensure the most homogenous possible membrane surface.
The production of the filter units is carried out under controlled conditions (clean-room class ISO 7). The components of the filter units are produced directly in our clean-room, where the largely automated final assembly and imprinting is also carried out.

During assembly, the filters are checked several times for any visible faults by means of sensors and a camera monitoring system. Following assembly, these are followed by the usual tests to the AQL standard, which monitor the bubble-point and the burst pressure of the filters. This checks the integrity of the membranes and connection of the membranes to the filter housing, together with the quality of the weld connection or edge-injection.
