Automatic X-Ray Film Duplicator. Constructed of stainless steel finished in durable baked enamel, our duplicators can be used with any available duplicating film. To operate the duplicators, simply place your film on the plexiglass screen with a sheet of duplicating film on top, close the cover and set the exposure time. The red light will signal you when exposure is complete. Turn off the built-in safelight and develop your duplicating film. Accommodates all x-rays up to 14" x 17".
