Do you know polyethersulfone (PES) flat membrane?

Zero-bound polyethersulfones (PES) microporous membrane, using proprietary membrane manufacturing technology, international advanced membrane production equipment research and development, and mass production.

Zero-bound polyethersulfones (PES) microporous membrane, using proprietary membrane manufacturing technology, international advanced membrane production equipment research and development, and mass production. The production line is designed and manufactured by the membrane machine manufacturer, and the computer automatically controls the operating conditions and procedures of the membrane production. The membranes produced have properties such as precise pore size control and reliable mechanical strength. All raw materials meet the standards and requirements of pharmaceutical-grade filter membranes.

Polyethersulfone (PES) membrane definition:

It is made of polyethersulfone ultrafine fibers by hot-melt adhesion. It is a kind of membrane material for deep filtration. It has the following characteristics: it uses food-grade isotactic polypropylene as raw material, and there is no additive in the whole production process; physical, It has stable chemical properties and good compatibility; it has a series of pore sizes, high porosity, large dirt holding capacity, recoil and high-temperature disinfection; good pressure resistance.

The advantages of polyethersulfone (PES) membrane products:

1. Compliant with United States Pharmacopeia (USP) bioreactivity testing, in vivo biosafety, cytotoxicity, and hemolytic testing.

2. For the 0.22µm filter, the batch samples passed the bacterial challenge test of Brevundimonas diminuta (Pseudomonas deficient) (ATCC19146) at 10E7 CFU/cm2 according to the latest version of ASTM F838-05 method.

3. The optimized built-in highly asymmetrical pre-filter layer can achieve maximum flow and excellent dirt holding performance.

4. The filter membrane is highly hydrophilic and can be quickly and completely wetted to achieve an excellent flow rate and high-throughput filtration. Ease of integrity testing.

5. High chemical compatibility in a wide pH range, extremely low protein adsorption, ensuring effective filtration, and maximum recovery of active ingredients.

6. Compatible with standard sterilization methods such as EtO, gamma rays, and SIP/autoclave.

Zero-boundary polyethersulfone (PES) sterilizing microporous membranes are highly asymmetric membranes with distinct uniform retention layers and gradient pore size pre-filtration layers, with the ability to retain particles and microorganisms of various sizes. With high porosity, it ensures large flux, low-pressure drop, and long service life.

Salient features of polyethersulfone (PES) membranes:

• Highly asymmetric structure

• Easy to wet with water

• Large throughput

• High pollution holding capacity

• High mechanical strength
  

• High porosity

• Low protein adsorption

• Low extractables

In addition to the wide range of applications in the pharmaceutical and biotechnology industries, Zero Boundary PES membranes are also suitable for other fields such as medical, food, and beverage as well as drinking water, microelectronics, fine chemicals, etc. We will provide extensive assistance and cooperation to ensure that our filters meet the technical and regulatory requirements in your industrial application and operation.
