The main application of membranes filter is the filtration of air, gases or chemicals. Membrane filters provided by Hawach have excellent chemical compatibility so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant.
Moreover, it is available in pore sizes from 0.1 um to 10 um and multiple diameters, and therefore excellently suited for the particle removal from solvents. Besides, there is no worry about contamination because all of them are made in a cleanroom. Longer lifetime is guaranteed by fresh sterilization and good thermal stability.
Tips for Membranes Filter
There are some tips for type-selection. Nylon membranes filter is fit for filtration of aqueous biological solutions, alcoholic solutions, and non-aqueous HPLC/GC solvents, it is therefore recommended for the chemical industry. Sterile MCE grid membrane filter is not normal mixed cellulose esters membrane, its special color contrast provided by the membrane surface is good for particle detection and bacteria recovery, and the membrane filter provides with a high degree of the internal surface area for adsorption of solvents, so it is also suitable for food and beverage test applications.
After a period of use, the membrane filter will be contaminated or blocked, which will decrease the water permeability and the filtration speed. Therefore, it is necessary to clean the membrane filter in time to prolong its separation performance and the water flux. Here below are the two most common and effective cleaning methods.
