Method of storing Hypam Rapid Fixer
I use fixer in a method I call "1-2-Fix" which is a one-shot, two-bath scheme. So for every roll I make-up a solution using a certain amount of concentrate per roll (10-15 ml, depending on type of film). To insure the concentrate stays fresh in storage, I broke the 5L bottle down into four 1-liter bottles and two 500 ml bottles. The bottles came from spring water and vitamin water drinks, respectively, and are PET, excellent for chemical storage. Although not shown in the picture, I also store concentrate in two smaller bottle sizes, 178ml and 37ml. At any one time I have only one 37 ml bottle that is partially full. When all of the small bottles are empty, I refill them with one of the 178 ml bottles, and when two 178ml bottles and the small bottles are empty, I refill them with one of the 500 ml bottles. This way only a few ml of stock solution is ever exposed to a part-full bottle, which minimizes oxidation. I am careful to label the bottles, as the concentrate still looks like water (I have no small children around the house).
