Product Advantages
The product adopts a full PFA architecture design. The filter membrane is made of high-precision PTFE microporous membrane. All components in contact with fluid, including the outer shell, central rod, end caps, and flow guide layer, are made of high-purity PFA material and integrally formed using hot-melt welding technology, eliminating the risk of structural loosening and contaminant release from the source. PFA gives the product three core characteristics:
- Extreme corrosion resistance: It can withstand the erosion of strong acids (such as hydrofluoric acid), strong alkalis, strong oxidants, and various organic solvents, maintaining stable physicochemical properties over a wide temperature range, and is suitable for most harsh chemical environments;
- Ultra-high purity: The surface is smooth and dense, with no metal ion release, ensuring stable resistivity of the filter medium;
- Structural durability: The folded design allows for a filtration area of 0.7㎡/10", and the reinforced support layer can withstand a positive pressure difference of 4 bar (21℃). It maintains its integrity after repeated high-pressure sterilization, achieving an absolute sterilization rate.
Key application scenarios
Leveraging the exceptional corrosion resistance and ultra-high purity of its perfluorinated structure, the product is deeply adaptable to core processes across multiple industries. Major chain application scenarios are detailed below, providing precise support for filtration needs in various operating conditions:

In biopharmaceuticals, it covers three compliant scenarios:
- Sterile drug production: Filtering microorganisms and foreign matter from antibiotics, vaccines, and other drug solutions to meet GMP aseptic requirements;
- Culture preparation: Filtering impurities from glucose, peptone, and other culture medium raw materials to prevent contamination of cell culture systems;
- Purified water preparation: Filtering trace colloids and particles from purified water after reverse osmosis to ensure water quality meets pharmacopoeia standards.
In high-end chemicals and laboratories, it is further divided into four typical scenarios:
- Fine chemical synthesis: Filtering impurities from reaction solutions after strong acid catalysis to improve product purity;
- Solvent recovery: Filtering residues from recovered solvents such as methanol and acetone to achieve solvent recycling;
- Laboratory reagent preparation: Filtering trace impurities from standard solutions to ensure accurate test data;
- Electroplating solution filtration: Filtering metal oxide particles from chromium and nickel plating solutions to prevent pinhole defects in the plating layer.

FAQ
What customization needs does your company support for PFA filter cartridges?
We support full-dimensional customization, including basic specifications, filtration accuracy, and structural design (besides sealing interfaces such as 222/226, we can customize special interfaces such as quick-connect and flanges). We can also optimize temperature and pressure resistance parameters and filter membrane pore size distribution according to operating conditions, adapting to the specific processes of industries such as semiconductors and photovoltaics.
What is the minimum order quantity for customized orders?
Flexible minimum order quantities. The delivery cycle for standard customized orders is 15-20 working days. Rush orders are negotiable.
As a filter wholesaler, what bulk purchasing support does your company offer?
Bulk purchases enjoy tiered pricing discounts and free sample testing; we support inventory warehousing services for long-term strategic partners to ensure stable supply; we provide dedicated account managers to provide one-stop services such as real-time order tracking and after-sales technical support.
Can customized or wholesale products guarantee the same quality as standard products?
Completely the same. Whether customized or wholesale, all products are manufactured in a Class 100 cleanroom, using the same batch of high-purity PFA and PTFE filter membranes. Each product undergoes integrity testing, and the entire process is controlled under the ISO 9001/14001 system. Bulk orders can be accompanied by sampling inspection reports and full lifecycle traceability services.
Are there industry-specific solutions for bulk purchases in different sectors?
Yes. For example, for the semiconductor industry, we offer customized low-leaching models with matching clean packaging; for the photovoltaic industry, we can customize hydrofluoric acid-resistant models. Bulk orders include installation guidance and maintenance training to reduce subsequent operating costs.
