fDesc[0] = "Chemical Calculator 6.0 is a shareware program designed for chemists, biologists and other scientific professionals. Its main purpose is to perform the calculations involved in the calculation of the amount of reagent to use when mixing up solutions. If you have ever worked in a lab you probably know how time consuming these calculations are. You probably also know how easy it is to make a mistake in one of these calculations and ruin an experiment that may take days or weeks to repeat. <br /> What Can Chemical Calculator Do For You? <br /> Suppose you want to mix up 40 ml of a solution containing: <br /> 1) 140 mM NaCl (MW 58.5)<br /> 2) 1 % SDS (MW 288.38)<br /> 3) 10 mM Streptomycin (MW 581.58) starting from a 10 mg/ml solution<br /> 4) 10 mM Ethylene Glycol (MW 62.07 liquid, density = 1.11) <br /> How long would it take you or your lab techs to figure out how much of each chemical to use? How sure are you that you are correct.? Using Chemical Calculator you can do it correctly in seconds and have a printout to take with you. It doesn&#039;t matter if the reagent is a solid, liquid, or a solution. Chemical Calculator can do it.";
