I have a question. Can I save the stabilizer working solution from Tetenal kit and use it towards a Freestyle kit that does not come with the stabilizer? How long will the stabilizer last in the mixed form?
Yes, the Tetenal STAB contains everything that could be missing from other kits: formalin and rinsing agent.
According to their booklet that comes with the kit, STAB lasts about a year.
BTW, PhotoEngineer has posted a STAB recipe on APUG, if you want to mix it yourself.
Trying to be the best of whatever I am, even if what I am is no good.
