Precision Liquid Filtration
Safeguarding Every Drop
JIUNYUAN Technology focuses on semiconductor- and pharma-grade liquid filtration. From pleated and capsule filters to activated carbon, depth filters, hollow fibers, filter bags and housings, we offer a complete product line plus validation and PTFE reclaim services.
Liquid Filtration Product Line
Pleated Cartridge Filters
Large surface-area pleated cartridges in PES, PTFE, PVDF, PP, Nylon66 and UPE media for semiconductor, pharma and precision chemical point-of-use filtration.
Disposable & Capsule Filters
Disposable capsule filters for small-batch, high-purity and cross-contamination-sensitive applications in PES, PTFE, PVDF and Nylon66 media.
Activated Carbon Filters
Activated carbon block, fiber and cloth cartridges for organic removal in water treatment, solvent purification and odor control.
Depth Filters
PP melt-blown depth cartridges with high dirt-holding capacity and long service life, ideal for high-flow pre-filtration and UPW systems.
Hollow Fiber Membrane Filters
Hollow fiber membranes offer ultra-high surface area with low pressure drop for UPW, biopharma and high-flow applications.
Filter Membranes & Syringe Filters
Disc membranes, syringe filters and coupon media for analytical lab sample prep and QC processes.
Filter Bags
Liquid filter bags including standard and absolute-rated bags plus anode bags for plating — ideal for high-flow pre-filtration.
Filter Housings
PFA fool-proof lock housings and multi-bag housings paired with matching cartridge and bag systems.
Validation & Reclaim Services
Filter retention validation, metal and organic cleanliness analysis, ICP-MS testing and PTFE filter reclaim services.

Frequently Asked Questions
What liquid filtration products does JIUNYUAN offer?
We offer nine product categories: pleated filters, disposable/capsule filters, activated carbon, depth filters, hollow fiber membranes, membrane & micro filters, filter bags, filter housings, and validation & reclaim services — covering pre-filtration through sterilizing-grade applications.
How do Semi-grade filters differ from industrial filters?
Semi-grade filters are designed for semiconductor wet chemicals and UPW systems. They must pass metal ion, TOC, particle and extractable cleanliness validation. Our Semi-grade portfolio is supplied with full cleanliness documentation.
Do you provide third-party validation or testing?
Yes. Our in-house lab runs particle challenge testing, ICP-MS metal analysis, organic extraction and customized test protocols to evaluate filter performance and cleanliness.
How does the PTFE filter reclaim service work?
We clean and validate spent PTFE filters with a full cycle of inspection, reclaim, cleanliness verification and return report — reducing procurement cost and supporting sustainability.
