Impact® 2-DUO and DUO LRN Disposable Filters

UPE Seiving and Polyamide Nonseiving Membrane Layers
Dual functionality disposable filters for advance point-of-use photoresist filtration


● Protects advance processes against defect-causing gels, particles and/or molecular polymers
● Combination UPE membrane and polyamide layer to maximize sieving and nonsieving retention
● Low hold-up volume minimizes chemical waste
