As a manufacturer with over two decades of experience in metal filtration solutions, Anping County Boli Hardware Wiremesh Products Factory is proud to present our Pharmaceutical Grade Copper Powder Sintered Filter – a precision-engineered component designed for sterile filtration applications. Manufactured under strict quality control in our Hengshui, Hebei facility, this 0.22 micron filter ensures exceptional particle removal while maintaining high flow rates. The 1/2" NPT connection makes it easy to integrate into existing pharmaceutical, biotech, and laboratory systems. Our factory has been a trusted supplier since 1998, exporting to major markets worldwide including North America, Europe, and Southeast Asia.
This filter is crafted from high-purity copper powder through advanced sintering technology, creating a porous structure that captures contaminants down to 0.22 microns – ideal for sterile filtration of gases, liquids, and air. The copper material offers natural antimicrobial properties, reducing the risk of bacterial growth in the system. Our rigorous manufacturing process ensures consistent pore size distribution and mechanical strength, providing reliable performance in demanding environments.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between this copper filter and a stainless steel filter?
A: Copper offers natural antimicrobial properties, which help reduce bacterial growth. It is also more thermally conductive, making it suitable for applications requiring rapid temperature changes. Stainless steel filters are typically used for corrosive environments, while copper is preferred for sterile filtration in pharmaceutical and food industries. -
Q: Can this filter be used for sterile liquid filtration?
A: Yes, the 0.22 micron pore size is suitable for sterile filtration of liquids, but it is important to verify compatibility with the specific liquid (e.g., pH, viscosity). For high-viscosity liquids, a pre-filter may be recommended. We can provide technical guidance based on your application. -
Q: How do I clean and reuse the filter?
A: The filter can be backwashed with clean water or compatible solvent, ultrasonically cleaned in a bath, or autoclaved at 121°C. Avoid using harsh chemicals that may damage the copper structure. We recommend inspecting the filter after each cleaning cycle. -
Q: What is the maximum operating temperature and pressure?
A: Standard operating temperature is up to 200°C, and pressure up to 10 bar (145 psi) at room temperature. For higher temperatures or pressures, custom designs are available upon request. -
Q: Do you provide certificates of material or performance?
A: Yes, we can provide material test reports, bubble point test results, and other quality documentation upon request. Please specify your requirements when placing an order. -
Q: What is the lead time for standard and custom filters?
A: Standard filters (1/2" NPT, 0.22 micron) are typically in stock or have a lead time of 7-15 days. Custom dimensions or special thread types may require 15-30 days depending on complexity. Contact our sales team for accurate lead time. -
Q: Is this filter suitable for use in autoclave sterilization?
A: Yes, the copper material is compatible with autoclaving at 121°C (or higher). The sintered structure can withstand repeated sterilization cycles without degradation. -
Q: What is the minimum order quantity (MOQ)?
A: For standard filters, the MOQ is 10 pieces. For custom designs, MOQ may vary. We welcome small trial orders for new customers.
