These point-of-use filters meet small to mid-volume photochemical filtration needs for positive developer and DI water applications. Both Optimizer® DEV filters (for developer applications) and Optimizer® DI filters (for DI water applications) require no pre-wetting, so the filters function immediately after installation. The design also limits the handling of hazardous chemicals during the installation and promotes a healthier workplace. Do not use either filter with aromatic hydrocarbons.
