Reuse

Checked 21 October 2026

Kodak says whether Kodak XTOL may be reused depends on how it is used.

  • stock may be reused
  • 1+1 use once
  • 1+2 use once
  • 1+3 use once

Longer time for reuse: Rolls 1-5 per litre at the normal time; rolls 6-10 +15 %; rolls 11-15 another +15 % on the adjusted time; discard after 15 rolls per litre.

Capacity, as the maker states it: Full strength, unreplenished: about 15 rolls of 135-36 or 120 per litre, then discard. Diluted 1:1: one batch only.

The capacity of the full-strength developer with normal, unreplenished processing is approximately 15 rolls of 135-36 or 120 film (80 square inches [516 square centimetres]) per litre, with time compensation. ... Discard the developer after you process 15 rolls of film per litre. ... Use diluted developer only once. Do not replenish or reuse diluted developer. ... If you use XTOL Developer diluted 1:1, dilute it just before you use it, and discard it after processing one batch of film.
