Darkroom Film Processing Tray KAISER Lab Trays 24x30, plastic, 315×375×70 mm, red

KAISER Lab Trays 24x30 are plastic darkroom processing trays sized 315×375×70 mm designed for the controlled handling of chemical baths during black-and-white film and paper development. The trays feature a grooved bottom and a shallow profile that aid chemical flow and make removal of paper easier, while the red plastic construction offers high visibility in dim working conditions. Constructed from shock-resistant, acid-proof material, these trays tolerate typical darkroom environments and are suitable for tabletop use in small darkrooms, classrooms and hobby setups.

Advantages

The shock-resistant plastic construction reduces risk of cracking or chipping during routine use. Acid-proof material prevents corrosion from developer, stop bath and fixer solutions, and heat resistance up to 80° C (176° F) ensures dimensional stability during warmer processing steps. Grooved bottoms promote uniform chemical flow and make it easier to lift paper without dragging, while the shallow, stable form factor fits standard enlarger easels and tabletop work surfaces.

Suitable for

• Black-and-white film development in small darkrooms
• Processing photographic paper during printing and contact printing
• Educational lab demonstrations and hands-on photography classes
• Hobbyist and classroom tabletop processing setups

Key specifications

• External dimensions: 315 × 375 × 70 mm
• Material: shock-resistant, acid-proof plastic
• Color: red for visibility in low light
• Bottom design: grooved to enhance chemical flow and handling
• Heat resistance: up to 80° C (176° F)

How to use

Place the tray on a stable, level tabletop or in a tray rack and pour the required volume of developer, stop bath or fixer according to the chemical manufacturer's instructions. When processing paper, submerge and agitate gently to ensure even coverage; use the grooved bottom to guide the paper and lift it without excessive contact with the tray edges. Rinse and dry trays after use to remove residual chemicals and prevent cross-contamination between baths.

Usage recommendations

Use dedicated trays for developer, stop bath and fixer to avoid contamination. Allow trays to cool before pouring hot solutions and avoid abrasive cleaners to preserve the acid-proof surface. Store trays flat to prevent warping and inspect for damage before each session.
