Basic Theory Of Membrane Filter

Hawach Scientific always specializes in the production of round disc membrane filters and roll membrane filters. With decades of accumulated experience in working with the most difficult problems in filtration and sterilization of liquids, gas, and other samples, advanced production equipment, and scientific management, Hawach membrane filter can meet the diverse needs of customers with excellent quality, reasonable price, and the great variety of goods. A variety of pore sizes are available to meet different microbial detection requirements. Besides, all membrane filters are aseptically and independently packaged, which avoids potential contamination in the production and packing process.

Membrane filter plays an important role in the filtration industry. It removes almost all micro-organisms and particles and makes no influence on the ingredients while doing filtration, which is very crucial in the lab or other significant experiments. No matter why you filter, for analytical, sterilization, or any other purpose, there are many kinds of membranes specifically produced to meet your needs.

Materials and types:

Membranes are made of different materials, such as PTFE, PVDF, Nylon, MCE, CA, PES, GF, PP and so on. But which material you should choose depends on what kind of material you want to filter. Two common types of membrane filters are round disc membrane filters and roll type membrane filters. Because they all can be applied infiltration and sterilization of many samples.

Membrane abbreviations:
