Darkroom Lab Trays KAISER 24×30 cm, set for film and paper processing (4166)

KAISER Darkroom Lab Trays 24×30 cm (model 4166) are shallow, rectangular plastic trays intended for chemical processing of photographic paper and small film strips in analogue darkroom workflows. The 24×30 cm dimension fits standard paper sizes used for contact prints and smaller enlargements, offering a stable, easy-to-handle surface for immersion in developer, stop bath and fixer solutions as well as rinsing and gentle drying. The trays are made to withstand common darkroom chemicals and provide consistent volume and coverage for repeatable processing results.

Advantages

The trays are lightweight and stackable for compact storage while their shallow profile facilitates controlled solution exchange and minimal use of chemicals. Smooth internal surfaces help reduce residue and make cleaning straightforward. The size and shape are compatible with batch processing of multiple contact sheets or short film strips, enabling uniform chemical action across the workpiece.

Suitable for

• Chemical development of photographic paper and small film strips
• Contact printing and proofing
• Batch processing in home or educational darkrooms
• Archival copying and conservation tasks requiring careful chemical handling

Key specifications

• Internal usable dimension: approximately 24 × 30 cm suitable for standard contact sheets and small prints
• Rectangular, shallow profile to reduce chemical volume and allow even coverage
• Durable plastic construction resistant to common photographic chemicals
• Stackable design for space-saving storage

How to use

Place the KAISER 24×30 cm tray on a flat, level surface in the darkroom. Pour the appropriate volume of developer, stop bath or fixer to a depth that fully covers the paper or film to be processed while minimizing excess solution. Immerse the paper or film and agitate gently according to the chemical manufacturer’s recommended times and temperatures. After processing, transfer workpieces between trays for stop bath and fixing, then rinse in clean water. Clean the trays after use with water and a mild detergent if necessary, and allow them to dry before stacking.

Usage recommendations

Use separate trays for developer, stop bath and fixer to prevent cross-contamination. Monitor solution temperatures and change chemistry regularly for consistent results. Store trays away from direct sunlight and extreme heat to preserve material properties.
