Self-developing intraoral radiographic film that does not require a darkroom or liquid preparation. With the built-in monobath, immediate development is achieved with brighter and more detailed definition than its predecessor Eco-30, and with lower exposure to X-rays than any other self-developing radiograph. Its ergonomic shape allows for more comfortable positioning in the posterior teeth, enabling the use of the parallel device for all precise angles, including anterior teeth. Only 50 seconds for development and fixation without contact with liquids on hands or clothing, and the monobath remains inside the bag, which can be disposed of in special waste containers.
