Our bound edge design offers distinct advantages over standard cut-edge discs. The welded rim eliminates the risk of loose wire ends contaminating the filtrate – a critical factor in pharmaceutical applications. Furthermore, the reinforced edge provides additional rigidity, allowing the disc to withstand higher differential pressures without deformation. This results in longer service intervals and reduced maintenance costs.
The 20μm pore size is carefully selected to balance flow rate and particle retention. It effectively captures particles down to 20 microns while maintaining a high throughput, making it suitable for polishing filtration of APIs, intermediates, and final drug products. The 316 stainless steel construction ensures compatibility with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols, helping you maintain regulatory compliance.

Frequently Asked Questions
-
Q: What is the difference between bound edge and plain edge filter discs?
A: A bound edge disc has a welded or rolled rim that reinforces the circumference, preventing wire unraveling and providing a better seal in filter housings. Plain edge discs are cut directly from mesh and may have loose wire ends. For pharmaceutical applications, bound edge is recommended to avoid contamination. -
Q: Can this filter disc be sterilized?
A: Yes, 316 stainless steel can withstand autoclaving at 121°C (250°F) and dry heat sterilization up to 180°C. Please confirm compatibility with your sterilization cycle. -
Q: Is a certificate of material compliance available?
A: Yes, we can provide a material test certificate (MTC) for 316 stainless steel upon request. Please specify when placing your order. -
Q: What is the typical lead time for this product?
A: For standard sizes (200mm, 20μm), lead time is 7–10 business days. Custom orders may require 15–20 business days depending on complexity. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer sample orders with a small fee, which is refundable for first bulk orders. Samples are shipped within 5 days. -
Q: How should I store these filter discs?
A: Store in a clean, dry environment away from corrosive chemicals. Keep in original packaging until use to avoid contamination. -
Q: Do you offer custom pore sizes or diameters?
A: Yes, we can produce discs with pore sizes from 1μm to 500μm and diameters from 20mm to 800mm. Contact our sales team with your requirements. -
Q: What is the minimum order quantity (MOQ)?
