摘要： The invention relates to a filtration unit which can be tested for integrity and has hydrophilic porous membranes (2) which at their edge regions are embedded in a fluid-tight manner by means of thermoplastic polymer material in anchoring elements (5), exhibit no edge water repellence and have greater filtration reliability and efficiency. It was found that filtration membranes of this type can be produced if hydrophilic porous membranes (2) are embedded at their edge regions by means of thermoplastic polymer material in a fluid-tight manner in anchoring elements (5) which at least in their edge regions and on at least one side are joined using heat and pressure to at least one porous flat structure (1) of thermoplastic polymer fibres. The claimed filtration units can be used in particular as filter candles in areas requiring a high level of filtration reliability, in particular in the pharmaceuticals and food industry, in the medical and laboratory field and in biotechnology.

摘要： A filter cartridge that includes a track etched membrane sealed therein in a leak-free manner, and a method for making the cartridge. The filter cartridge has a bubble point that is at least 50 % of the bubble point of the track etched membrane. In one embodiment, the method includes disposing the track etched membrane below a heat source and orienting the membrane so that it melts back on itself, and then allowing the membrane to cool to form a leak-free seal.

摘要： A membrane filtration module is disclosed for use in fluid processing systems in which all active connections between the module and the fluid processing system are located only on one end of the module. A central flow conduit within the module directs all of the flow of liquid from one of the connections to the opposite end. In this manner, dead volume is essentially eliminated as the flow pattern causes the liquid to sweep all the volume within the module while still providing for easy installation and replacement by virtue of having all of the active connections on only one end.
摘要翻译： 公开了用于流体处理系统的膜过滤模块，其中模块和流体处理系统之间的所有有源连接仅位于模块的一端。 模块内的中央流动导管将液体的所有流从一个连接引导至另一端。 以这种方式，基本上消除了死体积，因为流动模式导致液体扫过模块内的所有体积，同时仍然通过仅在一端具有所有有效连接而提供了易于安装和更换。

摘要： A pleated, all poly(tetra-fluoro ethylene) filter element (20) incorporating a poly(tetra-fluoro ethylene) filter membrane (24) is shown and described. The membrane is supported by an all poly(tetra-fluoro ethylene) paper (26) and (28), which permits filtrate to pass through the paper and across the poly(tetra-fluoro ethylene) membrane. A sandwich is formed by placing a layer of poly(tetra-fluoro ethylene) filter membrane (24) between the two layers of poly(tetra-fluoro ethylene) support paper, (26) and (28), and the sandwich is then pleated prior to assembly around a core (14) and between end caps (12) and (18), which are bonded to the poly(tetra-fluoro ethylene) paper and poly(tetra-fluoro ethylene) filter membrane by a hot-melt process.
