Solvent, Acid Or Base Chemical Delivery Unit (CDU)

JST’S Chemical Delivery Unit (CDU) is a proven, safe, and reliable method of dispensing chemicals to single or multiple wet benches without down time.  The CDU provides an enclosed, dual contained, exhaust area for chemical drums or day tanks.

Acid and base Chemical Dispensing Units include glove ports for changing drums without opening the cabinet, isolating personnel from hazardous chemicals and fumes.  Solvent Cabinets are dual wall designed and suitable for use as a flammable liquid storage cabinet.  They are designed for ease of maintenance activities and come with our standard 24/7 Technical Support.
