Response to photo-flo handling

Per liter of distilled water add 2.5ml photo-flo (1/2 strength) and 25ml isopropyl alcohol (70% PLAIN rubbing alcohol is OK). Use it one- shot and you'll get no spots or scum. I mix batches smaller than 1l using small medicine bottles with eyedroppers for the alcohol and photo-flo. I insert and remove the reel in the liquid gently to minimize foaming, remove the film from the dripping reel, hang the film up and let the liquid drain off. It's better to minimize wet time of the emulsion regardless of which chemical it's sitting in.
