Absolute concentrations for disinfecting
Roger was good enough to post ratios for common disinfectants and a length
of time for soaking.
Would Roger (or someone else) also say what absolute concentrations we're
talking about? That is, when the ratio is 1:1000, are we talking
gram:grams, teaspoons:teaspoons, or some kind of solution that itself is a
percentage (1 cc of 12% solution to 1 liter of water)? Thank you.
