As a manufacturer with over 26 years of experience in wire mesh and filtration products, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Custom Glass Fiber Filter Cartridge for Pharmaceutical Filtration, designed to meet the rigorous demands of sterile liquid processing. With an annual export value of US$5–10 million and shipments to major global markets including North America, Europe, and Southeast Asia, we have established a reputation for reliable, high-performance filtration solutions. Our 0.22 micron sterile grade filter cartridge is engineered to remove microorganisms and particulates, ensuring product purity and process integrity.
This filter cartridge utilizes advanced borosilicate glass fiber media with a graded density structure, providing high dirt-holding capacity and consistent retention efficiency. The 0.22 micron absolute rating makes it suitable for critical pharmaceutical applications such as sterilizing filtration of injectables, buffers, and biological solutions. Our cartridges are manufactured under controlled conditions to minimize extractables and ensure batch-to-batch consistency.
Key Features & Technical Specifications
- Filtration Media: High-purity borosilicate glass fiber, binder-free for low extractables.
- Micron Rating: 0.22 micron absolute (per ASTM F838-15).
- Sterility: Validated to achieve 107 CFU/cm² reduction of Brevundimonas diminuta.
- Flow Rate: High flow rates with low pressure drop – typical 0.5–1.0 bar at 10 L/min for 10-inch cartridge.
- Durability: Core and end caps made of polypropylene (PP) or stainless steel (optional).
- Temperature Range: Continuous operation up to 80°C (176°F) at 2.1 bar differential pressure.
- Customization Options: Available in lengths 10, 20, 30, 40 inches; end cap styles 222, 226, flat, or open; O-ring materials EPDM, silicone, Viton®.

Frequently Asked Questions
- Q: Can this cartridge be steam sterilized in place (SIP)? A: Yes, our glass fiber filter cartridges are designed for SIP at up to 135°C for 30 minutes. Please specify when ordering for optimal performance.
- Q: What is the typical flow rate for a 10-inch cartridge? A: For water at 25°C, a 10-inch cartridge can achieve approximately 10 L/min at 0.5 bar differential pressure. Actual flow depends on fluid viscosity and temperature.
- Q: Do you provide validation documentation? A: Yes, we provide a validation guide including bacterial retention test data, extractables profile, and bio-burden challenge results upon request.
- Q: What end cap configurations are available? A: We offer 222, 226, flat, and open end caps. O-ring materials include EPDM, silicone, Viton® (FKM), and PTFE-encapsulated silicone.
- Q: Is this cartridge compatible with aggressive solvents? A: The glass fiber media is chemically resistant, but for aggressive solvents we recommend confirming compatibility with our technical team. Polypropylene components may limit resistance.
- Q: How long is the lead time for custom orders? A: Standard custom cartridges (non-stock length, end cap, O-ring) ship within 15–20 working days. Rush orders can be arranged.
- Q: Can I get a sample before bulk order? A: Yes, sample cartridges are available for evaluation. Please contact our sales team for sample pricing and shipping.
- Q: What is the warranty coverage? A: Our 1-year warranty covers manufacturing defects. It does not cover misuse, improper installation, or chemical incompatibility.
