Disposable & Capsule Filters

Disposable capsule filters for small-batch, high-purity and cross-contamination-sensitive applications in PES, PTFE, PVDF and Nylon66 media.

Disposable and capsule filters integrate membrane, housing and fittings into a one-piece sealed device — eliminating the disassembly, cleaning and cross-contamination risks of traditional cartridge-plus-housing setups. They are particularly suited to small-batch, high-purity, and single-use applications. JIUNYUAN capsule filters are offered in PES, PTFE, PVDF, Nylon66, Glass Fiber and PP media with retentions from 0.1μm to 5μm.

Compared with traditional reusable cartridge systems, capsule filters offer four advantages: no cleaning SOP overhead, fully enclosed design preventing product exposure, pre-sterilization (gamma irradiation or autoclave) for aseptic production, and reduced process validation complexity through ready-to-use delivery. Every capsule passes 100% integrity testing (Bubble Point / Forward Flow) at the factory, with full batch documentation available on request.

Typical applications: pharmaceutical pilot batches, biotech R&D and GMP clinical batches, point-of-use filtration of small-volume specialty chemicals in semiconductors, laboratory sample prep, diagnostic reagent clarification, and sterile filtration of cosmetics and essential oils.

Frequently Asked Questions

When should I use capsule filters vs. traditional cartridge-plus-housing?
Capsules are recommended for small batches (<1,000 L/batch), pharmaceutical R&D, GMP aseptic batches, and high-value or cross-contamination-sensitive products. Traditional cartridge + housing is more economical for large-volume continuous production with cleanable reuse.
Can capsule filters be autoclaved?
Yes — standard capsules withstand 121°C / 30 min SIP for at least 3 cycles. Confirm housing material: PP housings are slightly less heat-tolerant than PSU. For multiple sterilization cycles, select PSU high-temperature versions or pre-gamma-irradiated (25 kGy) capsules.
Do capsule filters require integrity testing?
GMP regulations require pre- and post-use integrity testing (Bubble Point or Forward Flow) on every sterilizing-grade capsule. JIUNYUAN tests 100% of capsules at the factory with certificates provided; users must still validate per their SOP before and after use.

Endotoxin Sources and Removal in Pharmaceutical Water: Key Filter Selection Criteria

Endotoxin (LPS) survives 0.22 µm sterile filtration intact, making it the hardest contaminant to control in pharmaceutical water. This article examines LPS molecular structure and thermal stability, traces endotoxin sources in pharmaceutical water systems — including dead legs, biofilm, and feed water — and systematically compares four removal technologies: ultrafiltration (UF, MWCO 6–30 kDa), charge-modified depth filtration, distillation, and RO+UF in series, with LRV data for each. Includes a filter selection decision tree and LAL/rFC validation workflow to help engineers achieve USP <85> WFI compliance (≤0.25 EU/mL).
