Description of Nylon Filter Membrane:

The nylon filter membrane produced by HAWACH has the characteristics of good strength, complete size, and OEM customization. And pore ​​sizes have : 0.1μm, 0.22μm, 0.45μm, 0.8μm, 1.0μm, 3.0μm, 5.0μm, 10μm.

Advantages of Hawach nylon filter membrane:

  • A nylon filter membrane is a supported microporous filter membrane with good strength, high precision, and good hydrophilicity, which is produced by nylon N6/N66 solution through the advanced production process of mutual conversion.
  • All sizes: nylon membrane filter 0.22 and  0.45 micron nylon membrane filter, etc.
  • It can separate, purify, and enrich particles, foreign bodies, floating dust, and aerosols in liquid and gas phases
  • And is widely used in medicine and health, biochemistry, the microelectronics industry, environmental protection, and other departments.
  • The microporous membrane material is nylon, which has good hydrophilicity and is resistant to acid and alkalis of the appropriate concentration.
  • All products, like nylon membrane filter 0.22 and  0.45 micron nylon membrane filters are not only suitable for aqueous solutions containing acid and alkali, but also for organic solvents such as alcohols, hydrocarbons, ethers, esters, ketones, benzene, and benzene homologs, dimethylformamide, dimethyl sulfoxide, etc., are the most widely used microfiltration membranes.

Filter Membrane Disc Filter Membrane Roll

Features of Nylon Filter Membrane:

  • Roll film and sheet film optional
  • Pore ​​size: 0.1-10.0μm
  • Size: Disc Film: Φ25mm-Φ40mm
  • Roll film: 254mm, 260mm, 270mm, 280mm, 310mm
  • Fast flow rate, good retention effect
  • Less adsorption, no medium shedding
  • Low work pressure required
  • Used for filtration of alkaline solutions and organic solvents
  • Nylon filter membrane has very good mechanical strength, and strong adsorption, and can withstand most organic solvents and most alkaline solutions, especially suitable for filtration of alkaline solutions.
  • For organic solvent filtration, such as HPLC mobile phase particle removal filtration, a nylon membrane is more economical and practical than hydrophilic PTFE filter membrane.

Application areas:

  1. APIs. Medicinal solvents. Water for injection. Injections. Terminal filtration of infusion, etc.
  2. High-purity water. mineral water. juice. Soft drinks. wine. Liquor. beer. Terminal filtration of dairy products, etc.
  3. Photoresist. Terminal filtration of chemical reagents, etc.
  4. Plasma filtration.
  5. Membrane for the folded filter element.
  6. Can also be used as a transfer membrane.

Due to the relatively high adsorption performance of nylon membranes, it is generally not recommended for medium filtration or filtration of biological samples such as protein liquids to avoid sample loss due to adsorption. In this case, a low-adsorption cellulose acetate filter membrane (CA) is usually used, which is more suitable.
