The invention relates to a filter, a filter unit/module or a complete microfluidic device (e.g. a disposable cartridge for diagnostic purposes) with integrated filtration membrane for filtering a component or fluid from a sample and a method of manufacturing the filter, the filter unit/module or the complete microfluidic device with integrated filtration membrane, wherein the filter or filter unit/module or microfluidic device comprises a base portion comprising a microfluidic element to collect some filtered sample, and a web portion (10) made of a filter material an arranged on top of the base portion, wherein the web portion (10) comprises predetermined zones (40) of collapsed pores of the filter material, which define a filtering active area covering at least a part of said microfluidic element, the collapsed pores being adapted, to inhibit the filtering function of the filter material. |
