Features and Applications of Nylon Filter Membrane

As one of the most widely used filter membranes, the microfiltration membrane excels in its simple and quick use, large gas flux, high particle retention rate, excellent temperature resistance, good acid resistance, anti-aging, and non-stick, non-combustible, non-toxic, and good biocompatibility. So filter membranes can be used on many occasions: strong alkalis, organic solvents, and oxidants, to name just a few. The material is divided into two categories: organic and inorganic.

From the prospect of the separation characteristics of the microporous membrane, microporous membrane applications are to trap particles, bacteria, and other pollutants in the gas phase and liquid phase to achieve the purpose of purification, separation, and concentration.

For microfiltration, the retention characteristics of the membrane are decided by the pore size of the membrane. Generally, the pore size ranges from 0.1 to 1 μm, so the microporous membrane can separate large-diameter cells, suspended solids, and the like.

Features of Nylon Filter Membrane

  1. Pore Size Range: Nylon filter membranes are available in a range of pore sizes, allowing users to choose a membrane with the desired filtration characteristics based on the size of particles to be retained.

  2. Chemical Compatibility: Nylon membranes are chemically resistant, making them suitable for use with a wide range of solvents and chemicals commonly used in laboratory applications.

  3. Hydrophilic Nature: Nylon membranes are inherently hydrophilic, meaning they have an affinity for water. This property facilitates the passage of aqueous solutions through the membrane.

  4. Strength and Durability: Nylon filter membranes are known for their strength and durability. They can withstand moderate pressure differentials during filtration without compromising the integrity of the membrane.

  5. Low Extractables: High-quality nylon membranes exhibit low levels of extractables, ensuring minimal interference with the filtered sample.

  6. Wide Range of Sizes and Formats: Nylon filter membranes come in various sizes, including membrane discs and rolls, to accommodate different filtration setups and applications.

  7. Versatility: Nylon membranes are versatile and suitable for various filtration applications, including particle removal, sterilization, and clarification of aqueous and solvent-based solutions.

  8. Heat Resistance: Nylon filter membranes can withstand moderate temperatures, allowing for sterilization by autoclaving if required for specific applications.

Nylon filter membrane has a wide range of dissolution rates and low chemical properties.

The nylon filter membrane is hydrophilic, resistant to alkali but not acid, and is not easily corroded in ketones, phenols, ethers, and high molecular weight alcohols. Can withstand most organic solvents and most alkaline solutions, especially suitable for the filtration of alkaline solutions. Normal sterilization at 121°C without destroying membrane integrity.
