## Long description

KAISER Lab Trays 24×30 cm (model 4167) are rectangular darkroom processing trays sized for photographic prints and film development. These stackable trays are intended to hold chemical baths such as developer, stop bath and fixer during analogue photo processing. The tray dimensions make them suitable for common print sizes and for contact printing; they can also be used for mixing and diluting solutions and for temporary holding of negatives or paper between processing steps.
Advantages
The design provides stable, flat surfaces with raised edges to reduce spillage and allow safe handling of liquids. Being stackable saves workspace in studio and educational darkrooms and protects unused trays from dust when not in use. Made from chemical-resistant plastic, the trays withstand typical darkroom developer, stop and fixer solutions and are easy to clean. Their shallow depth and generous footprint give even chemical coverage across photographic paper and consistent development results.
Suitable for
 Black-and-white and colour print processing in darkrooms
 Contact printing of negatives onto photo paper
 Film developing when using trays for sheet or small-format negatives
 Mixing, diluting and holding chemical solutions
 Educational photography labs and small studio setups
Key specifications
 External footprint suitable for photographic paper up to approximately 24 × 30 cm
 Rectangular shape with raised edges to contain liquids
 Stackable construction for compact storage
 Chemical-resistant plastic material suitable for developer, stop bath and fixer
 Shallow depth for even chemical contact with paper and film
How to use
Place trays on a level, stable surface in the darkroom and pour the appropriate volume of developer, stop bath and fixer into separate trays according to the processing times of your paper or film. Insert photographic paper or negatives using tongs or gloved hands to avoid contamination. Agitate gently as required by your chosen process to ensure even development, then transfer paper through the sequence of trays. After processing, rinse and clean trays thoroughly to remove chemical residues and allow them to dry before stacking for storage.
Usage recommendations
Use separate trays for each chemical to prevent cross-contamination and label trays if multiple solutions are in use. Rinse trays immediately after use with running water and avoid prolonged exposure to highly concentrated chemicals to extend tray life.
