## Long description

KAISER Lab Trays 30x40 are plastic developing trays designed for handling photographic paper and sheets up to 30×40 cm. Finished in red, each tray measures 360×460×85 mm and is suitable for chemical processing, rinsing and temporary holding during darkroom work. The trays are made of shock-resistant, acid-proof plastic with a grooved bottom that improves chemical flow and simplifies removal of paper. A recessed pour spout accommodates a tray thermometer and facilitates controlled pouring of liquids.
Advantages
The shock-resistant plastic construction provides durability and resists cracking under regular darkroom use. Acid-proof material ensures long-term resistance to commonly used photographic chemicals. Heat resistance up to 80°C (176°F) allows safe use with warm solutions. The grooved bottom promotes even chemical distribution and helps lift paper easily, while stackable design supports organized storage and efficient workflow. The integrated pouring recess reduces spills and allows placement of a tray thermometer for accurate temperature control.
