Mixed Cellulose Microporous Filter Membrane

The mixed cellulose microporous filter membrane(microporous Glass Fiber filter membrane, Cellulose Acetate microporous filter membrane, MCE filter membrane) generally refers to nitric acid – acetic acid mixed cellulose ester microporous filter membrane, which is used for the filtration of bacteria and particles in connection with water quality, medical oil, lubricating oil, fuel oil, and scientific research laboratories.

Composition and Structure

Mixed cellulose ester filter membranes are made from a blend of cellulose acetate and cellulose nitrate. This combination creates a material with specific characteristics that make it suitable for a wide range of filtration tasks.

Mixed cellulose microporous filter membranes are composed of a blend of cellulose fibers, typically a combination of cellulose nitrate and cellulose acetate. This mixture creates a membrane with controlled porosity and permeability. The membranes are manufactured using advanced processing techniques to ensure consistent pore sizes and uniformity.

Key Features

  1. Uniform Pore Structure: Mixed cellulose microporous membranes have a controlled and uniform pore structure that allows for precise particle retention and filtration efficiency.
  2. Pore Size Range: These membranes are available in a range of pore sizes, typically from 0.1 μm to 10 μm, allowing them to be tailored for specific filtration tasks.
  3. High Porosity: The membrane’s high porosity ensures efficient flow rates while maintaining effective particle retention.
  4. Compatibility: Mixed cellulose membranes are compatible with a wide range of solvents, solutions, and gases, making them versatile for different filtration applications.
  5. Low Extractables: They have low extractable content, which is essential for applications where minimizing interference or contamination is critical.
  6. Hydrophilic Nature: Most mixed cellulose membranes are hydrophilic, which means they wet easily and do not require pre-wetting before filtration.
  7. Chemical Resistance: These membranes exhibit good chemical resistance to common laboratory solvents and solutions.

Performance of the mixed cellulose microporous filter membrane

It is brittle, easy to fracture, flammable, and has an electrostatic attraction. When in contact with more than 75% of alcohol, it is easy to expand and dissolve. It is also easy to produce toxic nitric acid and nitrite and other deficiencies in the alkaline solution.

Application of the mixed cellulose microporous filter membrane

  1. Microbial Analysis: Mixed cellulose microporous membranes are used for microbiological testing, such as sterility testing and microbiome analysis, where they capture and retain microorganisms.
  2. Particulate Removal: They are employed for the removal of particulates, contaminants, and debris from liquids and gases in various industries, including pharmaceuticals, food and beverage, and electronics.
  3. Clarification and Prefiltration: These membranes are used for the initial clarification and prefiltration of samples before more precise analytical techniques.
  4. Environmental Monitoring: Mixed cellulose membranes are used for water quality analysis and the collection of suspended particles from environmental samples.
  5. Air Monitoring: They can be used as air filters in air quality monitoring to capture airborne particles and particulate matter.
  6. Cell Culturing: Mixed cellulose membranes are sometimes used as cell culture supports or for filtration of cell culture media.
  7. The filtration of granules and bacteria, antibiotics, globulin, vaccine serum, and tissue culture in the pharmaceutical industry.
  8. The mixed cellulose microporous filter membrane can be used for air purification of a semiconductor device, preparation of high-purity water, purification of solvent, developer, and so on in the electronic industry.
  9. The filtration of the fine particles in the Daily chemical industry.
  10. The mixed cellulose microporous filter membrane can be used for drinking water filtration, and pond water bacterial filtration inspection in public health.
  11. Food industry: the filtration of sterilization and suspended impurities for juice, wine, and oil.

In summary, mixed cellulose microporous filter membranes offer uniform pore structures, compatibility with various substances, and effective particle retention. Their versatility makes them suitable for a wide range of applications, from microbiological analysis to general liquid and air filtration tasks in both laboratory and industrial settings.
