    Preguntas frecuentes

    Can Durapore 0.22 micron cartridges be used in the reverse direction? Durapore filters are bidirectionally supported. If the filter is inadvertently used in the reverse direction, a post-use integrity test will identify whether or not the filter cartridge was integral during processing. The specification for theis filter is > 50.0 psi for a water bubble point test and < 13.3 ml/minute per 10"element for a diffusion test. If the filter passes this test, no damage occured during use.

    Please note that the maximum allowable pressure specification is different in the reverse direction - 50 psid vs. 80 psid in the forward direction.
    What are the most common causes of filter clogging (air bubbles, particulates, surface tension, inappropriate filter size etc.)? Trapped bubbles, particulates and improper sizing are all common causes of fitration issues. True filter clogging is caused by particulates. Hard particles will form a cake on the filter surface. This will generally slow the filtration but not necessarily block filtration becuase fluid can flow through the layer of hard particles and then through the filter.

    Deformable particles can compress across the filter pores, forming impermeable barriers to filtration. This type of problem is common with solutions containing proteins or lipids.
