Store the concentrate in several small, well capped bottles.

For use dilute 1+19. Develop Tri-X, EI 400, for 12 min at 20 C. For enhanced speed expose at EI 2400 and develop for 14 min at 27 C. Agitate for 10 sec initially and for 5 sec every minute. These times are for the old TX available in 1975. Modern TX will probably have different times.

I have not used this developer with modern films and post it here as a curiousity.
