SILVER Estimation PAPER Use
When we buy Fixer Solution from Hospital laboratories OR Photo Bleach from Digital Photo Labs we blindly buy the stuff without judging what is the amount of SILVER may be present in it, by which on the either side Hospitals persons OR photo lab persons takes disadvantage of this by mixing same proportionate of water to the solution.
So we recommend using SILVER ESTIMATOR which in college language we call it YELLOW LITMUS PAPER while buying the solution. If you dip the half a side of the paper in the solution and color doesn’t change, then no doubt there is no silver in it.
Look at the estimator chart above, tells about content of SILVER in terms of GRAMS in 1 liter of FIXER / PHOTO BLEACH, by which it will be easy for you to judge the approx. amount of SILVER to make clean profit.
