About liquid mesurement
hello everybody
I need some advices about liquid measrement(sorry if my english is bad) from somebody who's expert. the fact is that I diluited too much a chemical, and I want it more concentrated. a theorichal example: a chemical we'll call RC 100mg(RC soluble in h2o) in 200ml(H2O) ==> [RC]concentration is 0,5mg in 1ml. I want to make it 1mg x 1ml or better 2mg x 1ml so I want to reduce the H2O volume by 100ml or more. My thought was to make water evaporate...but I fear to damage the chamical that is inside, or damaging it...is there some other way other than evaporation?
