Description
1. Product Overview
The PES filter cartridge is a high-performance polyethersulfone membrane filtration solution engineered for critical liquid purification processes. Its primary industrial use spans pharmaceutical, biotech, food & beverage, and microelectronics sectors where absolute microbial retention and low extractables are non-negotiable. The key value proposition lies in its superior flow rate, broad chemical compatibility, and validated sterilization performance that reduces downtime and total cost of ownership. It is strategically important in the market as regulatory pressure and yield optimization drive demand for reliable, single-use filtration that ensures product integrity and batch-to-batch consistency.
2. Key Specifications & Technical Characteristics
- Chemical composition or material components: 100% hydrophilic polyethersulfone (PES) membrane; polypropylene cage, core, and end caps; silicone, EPDM, or Viton O-rings available
- Purity level or grade: Pharmaceutical grade; meets USP Class VI, FDA 21 CFR, EC1935/2004; low protein binding; non-fiber releasing; <5 µg/cm² extractables
- Physical characteristics:
- Form: Pleated cartridge, 2.5″ to 40″ lengths; OD 69 mm standard
- Color: White membrane, white/blue polypropylene hardware
- Pore size: 0.04 µm, 0.1 µm, 0.2 µm, 0.45 µm, 0.65 µm, 1.2 µm absolute rated
- Filtration area: Up to 0.8 m² per 10″ element
- Max differential pressure: 4.0 bar @ 25°C; 2.4 bar @ 80°C
- Packaging options: Individually sealed in double-layer PE bag, 6 pcs/carton; bulk pack 24 pcs/case; customized OEM labeling available
- Shelf life: 3 years from date of manufacture when stored in original packaging, dry, <40°C, away from direct sunlight
3. Core Industrial Applications
- Primary industries that use this product: Pharmaceutical & biopharmaceutical manufacturing, vaccine production, IV fluids, ophthalmics, dairy & beverage, bottled water, wine & beer clarification, semiconductor wet-process chemicals, ultrapure water systems
- Specific operational use cases: Final sterilizing-grade filtration of drug formulations, bioburden reduction before filling, cold stabilization of beverages, particle removal in DI water loops, point-of-use filtration for etching and cleaning chemicals
- Why this product performs better than alternatives: PES provides inherently hydrophilic flow without wetting agents, delivering 30–50% higher throughput vs. PVDF or Nylon at same micron rating. Low protein adsorption preserves API yield in bioprocessing.
- Efficiency, durability, or cost advantages: Withstands >100 SIP cycles at 134°C or gamma irradiation to 50 kGy, extending service life. High dirt-holding capacity reduces change-out frequency, lowering operational OPEX and validation costs.
4. Competitive Advantages
- Quality consistency: 100% integrity tested during manufacturing; each lot supplied with Certificate of Quality and traceability. ISO 9001:2015 and ISO 13485 certified production.
- Supply reliability: Dedicated production lines with 8M pcs/year capacity; 98.5% on-time delivery rate; regional warehouses in US, EU, Singapore for 72-hour dispatch
- Logistics capability: Optimized packaging density; full-container direct shipments; experienced in DG and non-DG export documentation, CO, FTA, and REACH compliance
- Price competitiveness: Vertical integration from membrane casting to assembly enables 15–25% cost advantage at equivalent performance tier vs. Tier-1 brands
- Sustainability or environmental benefits: REACH & RoHS compliant; recyclable polypropylene construction; reduced flush water volume due to low extractables
- Technical support or documentation availability: Full validation guide, bacterial challenge data, extractables study, and regulatory support package. Global field engineers for installation and troubleshooting.
5. Commercial & Supply Information
