Determine the necessary mass, volume, or concentration for preparing a solution. Mass pg ng µg mg g kg = Concentration fM pM nM µM mM M x Volume nL µL mL L x M. Wt* g/mol *When preparing stock solutions, always use the batch-specific molecular weight of the product found on the vial label and the Certificate of Analysis (available online).
Determine the dilution needed to prepare a stock solution. Concentration 1 (C1) fM pM nM µM mM M x Volume 1 (V1) nL µL mL L = Concentration 2 (C2) fM pM nM µM mM M x Volume 2 (V2) nL µL mL L
The reconstitution calculator enables you to quickly determine the volume of a reagent needed to reconstitute your vial. Just enter the mass of the reagent and the target concentration, and the calculator will do the rest. Volume (to add to vial) ml µl = Mass (in vial) mg μg ng ÷ Desired Reconstitution Concentration mg/ml µg/ml ng/ml
