Description
The Clariflow®-E Mini is a high-purity PES capsule filter designed for semiconductor and microelectronics manufacturing applications that require reliable particle retention, low extractables, and contamination control in critical process fluids.
Built with a high-performance polyethersulfone (PES) membrane, the capsule delivers high flow rates, low pressure drop, and excellent chemical compatibility for ultrapure water (UPW), deionized water (DI), and aqueous chemical filtration processes.
Its compact, disposable encapsulated design helps reduce contamination risk, simplify maintenance, and streamline filter change-outs in cleanroom manufacturing environments where process integrity is critical.
Clariflow®-E Mini PES capsule filters are commonly used in semiconductor fabrication and microelectronics manufacturing for DI water filtration, aqueous chemical filtration, photoresist processing, and other high-purity applications requiring consistent particle control.
What is a PES Capsule Filter?
A PES capsule filter is a disposable filtration device that uses a hydrophilic polyethersulfone (PES) membrane to remove particles, colloids, and contaminants from high-purity liquids used in semiconductor and microelectronics manufacturing.
PES membrane filters are widely used in high-purity process applications because they provide:
- High flow rates with low pressure drop
- Low extractables and low ionic contribution
- Reliable submicron particle retention
- Low protein and particle binding
- Strong compatibility with aqueous chemicals and ultrapure fluids
- Consistent filtration performance in critical processes
These characteristics make PES membranes well-suited for contamination-sensitive semiconductor applications involving water-based process fluids.
