Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

Disposable filters, Optimizer® DEV and DI
Supplier: ENTEGRIS
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.
