Plastic developing trays for 30 x 40 cm (12 x 16") images. The developing tray has a well-shaped spout which also serves as a holder for the thermometer. The tray is suitable for developer, stop, fixer and hypo-clear baths and general use. Indentations on the bottom help stabilize the tray and prevent prints from sticking. The material is resistant to chemicals, even 60% acetic acid. The trays are very easy to clean and they can be stacked on top of one another to save space. The developing trays are available in beige, green, red and white and in different sizes.
