Featuring a stack of pleated filter discs (lenticular plates) in a sanitary housing, this filter offers high dirt-holding capacity (up to 5 kg/m²) and low residual volume (≤500mL), ensuring efficient clarification and sterilization of sensitive liquids.
Precision Filtration Design
Lenticular Plate Technology: Pleated cellulose, polypropylene, or nylon media provide 30% more filtration area than flat membranes, achieving log reduction values (LRV) up to 6 for microbial removal.
Graded Pore Structure: Depth filtration with upstream coarse media and downstream fine layers for efficient particle capture (0.1-100 microns).
Sanitary & Low-Residue
Housing Materials: 316L stainless steel with electropolished interior (Ra ≤0.5μm), compliant with USP Class VI and EU GMP Annex 1.
Zero Dead Leg Design: 3D-optimized flow channels ensure <50mL residual volume, critical for expensive biopharmaceutical solutions.
Process Efficiency
Quick Changeover: Single-clamp housing allows plate stack replacement in <10 minutes, reducing downtime in batch processes.
Sterilization Capability: Autoclavable at 121°C for 30 minutes or gamma-sterilized for aseptic applications.
Customizable Configuration
Plate Quantity: 1-10 plates per housing, supporting flow rates from 5 to 100 L/min based on media porosity.
Connection Options: Tri-clamp (ISO 2852), SMS, or NPT threads for easy integration into sanitary pipelines.
Pharmaceuticals:
Final filtration of parenteral solutions, protein therapeutics, and vaccine formulations (0.22μm sterile grade).
Biotechnology:
Clarification of cell culture supernatants, removal of cell debris, and virus filtration (10-50nm membrane options).
Food & Beverage:
Cold filtration of wine, beer, and fruit juices; removal of yeast and bacteria for extended shelf life.
Electronics:
Filtration of ultra-pure water (UPW) and photoresist chemicals for semiconductor manufacturing.
Q: Can lenticular filters be used for gas sterilization?
A: Yes, with hydrophobic PTFE media for air and gas filtration (e.g., sterile air supply to cleanrooms).
Q: How is the filter integrity tested?
A: Bubble point testing (for membrane plates) or pressure decay testing ensures no defects before use, compliant with ASTM F838.
Q: What is the maximum operating pressure?
A: Standard housings handle up to 10 bar; high-pressure models (20 bar) are available for demanding applications.
Q: Can the plates be reused?
A: Cellulose and polypropylene plates are single-use; some nylon plates can be cleaned and reused up to 5 times with proper CIP.
