DL Series High-Precision Pharmaceutical Grade Bag Filter for Cosmetic Chemical Processing
The DL Series High-Precision Bag Filter is specifically engineered for pharmaceutical, cosmetic, and fine chemical processing environments where product purity and process validation are non-negotiable. Constructed from electropolished SS316L stainless steel with validated filter media, it delivers consistent sub-micron particle removal in cGMP-compliant operations.
Pharmaceutical-Grade Design Features
Premium Materials: All product-contact surfaces are fabricated from SS316L stainless steel with electropolished mirror finish achieving surface roughness below Ra 0.4 micron, minimizing particle entrapment and bacterial adhesion.
Validated Filter Media: PTFE, nylon monofilament, and polypropylene filter bags with documented micron ratings from 0.5 to 100 microns, each lot-tested for retention efficiency.
CIP/SIP Compatibility: Designed to withstand Clean-in-Place and Steam-in-Place cycles at temperatures up to 150°C, enabling automated sanitation between batches without disassembly.
Full Documentation Package: Each unit ships with material certificates (EN 10204 3.1), surface finish measurement reports, hydrostatic pressure test certificates, and weld inspection records.
Sanitary Connections: Tri-clamp or DIN 11864 aseptic flange connections eliminate threaded joints and associated contamination risks.

Integrates seamlessly into validated cGMP production lines as secondary filtration or polishing stage.
Selection Guide: Specifying a Pharmaceutical-Grade Bag Filter for cGMP Applications
Pharmaceutical and high-purity applications require rigorous material selection and documentation. Use this guide for compliant specification:
Parameter
What to Consider
Recommendation
Product Contact Surface
Material and finish
SS316L minimum; Ra ≤0.4µ electropolished; no threaded joints in product-contact zone
Request bacterial challenge test data or particle efficiency curves for critical applications
Flow Rate
Batch volume and cycle time
1-bag: 5-30 m³/h; multi-bag: proportional; size for peak viscosity at lowest process temperature
CIP/SIP Requirements
Cleaning and sterilization
SIP-compatible up to 150°C; verify seal materials for steam cycle count rating and chemical resistance
Documentation Package
What certificates needed
EN 10204 3.1 material certs, surface roughness report, hydrostatic test, weld inspection, FDA/EP compliance
Connection Standards
Aseptic or sanitary
Tri-clamp (sanitary); DIN 11864 (aseptic with validated sterile barrier); avoid threaded connections
Extractables/Leachables
Product safety risk
Request extractables profile for filter bags and seals; critical for injectable and parenteral applications
Validation Support: We provide full documentation packages including material traceability, surface finish certification (Ra measurement), hydrostatic pressure test reports, and weld inspection records. Custom validation protocols (IQ/OQ) available upon request for cGMP installations.
Frequently Asked Questions
What documentation is provided for pharmaceutical validation?
Each DL Series pharmaceutical-grade unit ships with a comprehensive documentation package including: EN 10204 3.1 material certificates for all product-contact components, surface roughness measurement report (Ra values), factory hydrostatic pressure test certificate, weld inspection and NDE records, FDA/EP material compliance statements, and a certificate of conformance. IQ/OQ protocol documents available upon request.
Can the DL Series be sterilized with steam-in-place (SIP)?
Yes. The pharmaceutical-grade model with PTFE or high-temperature silicone seals is SIP-compatible at 150°C. Standard EPDM seals are rated to 120°C and may be used for hot water sanitization but not steam sterilization. Specify your SIP temperature and cycle count requirements when ordering to ensure correct seal specification.
What extractables and leachables data is available for filter bags?
We provide extractables profiles (solvent extraction studies) for PTFE, Nylon, and PP filter bag media upon request. These studies quantify organic and inorganic substances that may be released under worst-case process conditions. For injectable and parenteral applications, we recommend conducting a process-specific leachables study with your actual product stream.
What is the minimum order quantity for validated filter bags?
Standard filter bags are available from stock with no minimum order. Validated/lot-tested bags (with individual retention efficiency certificates) typically require a minimum order of 50 pieces per micron rating. Contact our technical sales team to discuss your validation requirements.
How do I clean the housing between API batches to prevent cross-contamination?
We recommend a validated CIP protocol: (1) Pre-rinse with purified water, (2) Alkaline detergent wash at 70-80°C for 20 minutes, (3) Purified water rinse, (4) Acid rinse if required for inorganic residues, (5) Final purified water rinse to conductivity endpoint. For high-potency APIs, we recommend dedicated housings or disposable bag liners to eliminate cross-contamination risk entirely.
