Kodak Indicator Stoppbad - 16 fl. oz.

The indicator dye in this stop bath makes it foolproof—I can see exactly when the solution's spent without guessing. Mixed a fresh batch and it cleared my prints in about thirty seconds flat. Glad my local store had it for pickup, since shipping chemicals is always a hassle.

Took a bottle to the darkroom for my fiber prints and the indicator does exactly what it says, shifting to yellow when exhausted. No guessing if the bath is spent, which saves me from wasted paper. Solid value for a 16 oz bottle that’ll last a while.

The color change from purple to yellow is so obvious that I can't miss the moment the bath is exhausted—perfect for a beginner like me. Works great for stopping development cleanly after using D-76.
