Description of Hawach MCE Filter Membrane:

A mixed cellulose ester (MCE) filter membrane is a standard commonly used membrane, a mixture of cellulose acetate (CA) and cellulose nitro (CN), with good pore-forming properties, good hydrophilicity, readily available materials, and low-cost, low protein adsorption.

Advantages of Hawach MCE filter membrane:

  • The HAWACH MCE filter membrane has been further improved in terms of flatness and uniformity and has better performance.
  • MCE filter membranes are biologically inactive, produced, and tested under strictly controlled conditions, and are one of the most widely used membranes in analytical and research applications.
  • It can be used for clarification and filtration of aqueous solutions, particle removal and analysis, and monitoring and testing of air quality. With high aperture accuracy, strength and toughness, it will not break, tear or bend even when handled with gloves or with tools such as tweezers.
  • It is used for chemotaxis and cell retention, and particle collection, and is also commonly used for ultra-clean filtration of solutions and light scattering measurements, as well as sterile filtration of aqueous solutions, and buffers, serum and culture media, and mobile phase filtration of HPLC.
  • Filters can be normally sterilized at 121°C without loss of integrity.
  • The MCE filter membrane has good temperature stability, and the entire filter membrane can be sterilized at high temperatures while ensuring its integrity.
  • And in this process, it maintains good anti-shrinkage performance to avoid tearing of the membrane, the reduction of the flow rate, and the reduction of the entire filtration volume in the filter.
  • For air monitoring applications, membranes can be dissolved using standard digestion procedures.

  • The membrane material has a smooth surface, light and thin texture, high porosity, good retention effect, good hydrophilicity, and large water flux.
  • The uniform adsorption rate of the microporous structure is extremely low, it is not resistant to organic solutions and strong acid and alkali solutions, and the filtration is resistant to pH 3.5-8. It is only suitable for the filtration of liquid medicines or other water solvents, with high-cost performance.
  • The uniform microporous structure of the membrane improves the filtration speed and has low protein adsorption characteristics.
  • Suitable for aqueous solution, not resistant to acid, alkali, and organic solvent.


  1. Determination of bacterial flora in sterilized and filtered water bodies of sterilization and particle removal medium and culture medium in the laboratory and small production process;
  2. Air monitoring and microbiological analysis;
  3. For routine laboratory sterilization and contamination analysis;
  4. Suitable for aqueous solutions, not resistant to acid, alkali, and organic solvents;
  5. The pharmaceutical industry needs autoclave sterilization water needles, and filter out particles for large infusions;
  6. For sterilization of heat-sensitive drugs (biochemical preparations such as insulin ATP, coenzyme A, etc.), use a 0.45 μm filter membrane (or 0.22);
  7. Analysis and determination of particulate and oil intolerant in solution, and determination of water pollution index;
  8. Research departments such as somatic cell hybridization and mitochondrial complementation prediction hybrid vigor research.

In addition, HAWACH also produces laboratory pre-filtration membranes such as PP filter membrane, glass fiber filter membrane, etc.
