Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Polyethylene Membrane Filter Element specifically designed for critical pharmaceutical filtration applications. With a precise 0.2 micron pore size and 10 inch standard length, this sterile-grade filter element ensures the highest level of particle retention and microbial removal. As a manufacturer with over two decades of experience since 1998, we combine advanced membrane technology with strict quality control to deliver consistent, reliable filtration performance for your most demanding processes.
Our filter elements are manufactured using high-purity polyethylene membrane material, which offers excellent chemical compatibility and low extractables. The 0.2 micron rating guarantees the removal of bacteria, yeast, and other microorganisms, making it an ideal choice for sterilizing filtration in pharmaceutical, biotech, and life science industries. Each element is produced in our ISO-controlled facility, ensuring batch-to-batch consistency and compliance with international pharmacopoeia standards.
Key Features & Benefits
- High Retention Efficiency: 0.2 micron absolute rating ensures >99.99% removal of bacteria (e.g., Brevundimonas diminuta) and particulate matter.
- Sterile Grade: Validated for sterilizing filtration, suitable for critical pharmaceutical processes.
- Low Extractables: Pre-washed and rinsed to minimize leachables, maintaining product purity.
- Chemical Compatibility: Resistant to a wide range of acids, bases, and organic solvents (pH 1–14).
- Thermal Stability: Can withstand autoclaving and hot water sanitization up to 121°C.
- High Flow Rate: Optimized membrane structure provides low pressure drop while maintaining high throughput.
- Integrity Testable: Compatible with bubble point and diffusion tests for in-process validation.
- Standard Dimensions: 10 inch length with industry-standard 2.5 inch outer diameter, fitting most housings.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 0.2 micron absolute and nominal rating?
A: Our 0.2 micron filter element is rated as absolute, meaning it retains 99.99% of particles of that size. This is critical for sterilizing filtration. Nominal rating is less precise and not suitable for sterile applications.
Q2: Can this filter be used for steam sterilization?
A: Yes, the polyethylene membrane can withstand autoclaving at 121°C for up to 30 minutes. However, please note that repeated steam cycles may reduce service life. In-line steam sterilization is also possible with appropriate housing design.
Q3: What end cap configurations are available?
A: We offer standard Double Open End (DOE) with 2-222 or 2-226 O-rings, as well as flat gasket versions. Custom end caps are available upon request with minimum order quantity.
Q4: How do I validate the integrity of the filter after installation?
A: Our filter elements are compatible with bubble point and diffusion tests. We provide typical bubble point values for 0.2 micron PE membrane (e.g., > 3.2 bar with water). Test protocols can be supplied upon request.
Q5: Is this filter element compatible with organic solvents?
A: Polyethylene is resistant to many organic solvents, including alcohols, ketones, and hydrocarbons. However, please check compatibility with specific solvents at your operating temperature. We can provide a chemical compatibility chart.
Q6: What is the typical flow rate for a 10-inch element?
A: For water at 25°C and 1 bar differential pressure, the flow rate is approximately 10–15 L/min. Actual flow depends on fluid viscosity and operating conditions. We can provide detailed performance curves.
Q7: Can you provide samples for testing?
A: Yes, we offer free samples for qualified customers. Please contact our sales team with your application details. Shipping costs are negotiable.
Q8: Do you have any certifications for the pharmaceutical industry?
A: Our manufacturing facility follows strict quality management systems. While we do not claim specific certifications unless provided, each batch is tested for integrity, extractables, and bacterial retention. We can provide batch certificates and validation guides upon request.
