Products Advantages
No Cross-Contamination
Single-use sealed design with thermally welded membrane-to-housing bond. No adhesive contacts the fluid path. The entire capsule is discarded after a single batch - no cartridge disassembly, no housing cleaning. Batch-to-batch isolation is maintained, suitable for small-volume pharmaceutical dispensing and active intermediate filtration.
the technical team
Each capsule ships as a complete filtration unit with integrated connections. Push tubing onto the hose barb or hand-tighten NPT threads to connect inline - no separate stainless steel housing or clamps required. When pressure drop reaches the replacement threshold, shut down, disconnect the used capsule, and install a new one within 5 minutes.
Application Conditions
| Industry | Process | Recommended Specification |
| Pharmaceutical | Small-volume injectable final filtration, buffer sterilization | 0.2μm PES |
| Biotechnology | Fermentation broth clarification, media sterilization, bioreactor venting | 0.2–0.45μm PES/PTFE |
| Semiconductor | DI water point-of-use filtration, photoresist/developer dispense-point filtration | 0.05μm PTFE |
| Food & Beverage | Purified water final filtration, gas sterile filtration | 0.2–1μm PES/Nylon |
| Fine Chemical | Solvent filtration, small-batch intermediate clarification | 1–50μm PTFE/Glass Fiber |
Operating Instructions
1.Pre-Installation Check: Verify packaging seal is intact. Confirm pore size, membrane material, and connection type match process requirements.
2.Pre-Installation Check: Verify packaging seal is intact. Confirm pore size, membrane material, and connection type match process requirements.
3.Connect to Line: Push hose barb into tubing and secure with a clamp; hand-tighten NPT threads; clamp sanitary flange into place.
4.Wet and Vent: Before full operation, open the downstream vent to purge trapped air from the housing, then close.
5.Start Filtration: Ramp pressure gradually to operating level. Avoid water hammer on the membrane surface.
6.Replacement Trigger: When pressure drop rises 1.5 bar above initial clean-state differential pressure, shut down and replace the entire capsule.
7.Disposal: Dispose according to process media classification. Sterilizing-grade capsules are not reused.
Frequently Asked Questions
- What pore sizes are available, and how do I select the right one?
Standard pore sizes: 0.05μm, 0.1μm, 0.2μm, 0.45μm, 1μm, 5μm, 10μm, 20μm, 50μm, 70μm. Select 0.2μm for sterile filtration of aqueous solutions. Select 0.45μm for microbial reduction and general clarification. Select 1–70μm for particulate removal and prefiltration. For semiconductor DI water and chemical dispense applications, 0.05μm PTFE removes fine particles at the point of use.
- How is the capsule packaged and shipped?
Each capsule is individually sealed in a clean packaging bag. The external label displays the model specification, batch number, and production date. Capsules are packed in standard export cartons with internal dividers and cushioning material to prevent transit damage. Each carton includes a packing list and the corresponding batch integrity test reports. Lead time is confirmed per order specification - Hanzhikang does not guarantee "in stock, ready to ship" without order confirmation.
- Is this filter reusable after cleaning?
No. The inline capsule filter is designed for single use and is not intended for cleaning, backflushing, or reuse. Membrane and housing are thermally welded as one unit and cannot be opened for inspection or cleaning. After the batch is processed or the replacement pressure drop is reached, discard the entire capsule. Reusing a single-use capsule compromises particle retention rating and risks cross-contamination.
- How do I know when to replace the capsule?
Replace the capsule when the pressure drop across the filter rises 1.5 bar above the initial clean-state differential pressure. Measure upstream and downstream pressure during operation. If the initial ΔP was 0.3 bar with clean water, replacement is triggered at 1.8 bar. Continuing beyond this point risks membrane damage or housing rupture under excessive differential pressure.
