I've been using Rodinal for going on 30 years and the concentrate in the bottle has lasted (except for the last 10ml) until I used it up, about 1 year. I use this for slow 35 & 120 films and for 120 FP-4.
Now my latest bottle is about 1/2 empty and my negs are about 1 stop thin. Same camera & dev procedure. I ran another roll thru Pyrocat HD (another fine dev) and the negs are fine.
Has anyone else noticed this? I'm using Adox APH09. I've noticed that Freestyle also sells another version of Rodinal. What, if any, is the difference? Will it last longer than APH09?
