This calculator allows you to calculate how much stock solution you need to add to a diluant in order to have the final desired concentration.

A quick calculator for calculating the mass of compound needed in a volume of solvent to achieve a desired concentration in milli-M.

This calculator allows you to calculate how much enzyme to add to a stock solution in order to achieve the desired enzyme activity in your final solution.

This calculator is used for calculating how much dilution is required to dilute a stock solution whose weight is given in weight/volume into a more dilute sample where the units are microM, we typically use this for hydrogen peroxide which is sold at 30 % w/v concentrations.

This calculator is used to calculate the pH obtained when dilutions a strong acids such as sulphuric acid, nitric acid, hydrochloric acid etc in an aqueous buffered solution.

This calculator is an approximation for calculating the hydrogen peroxide in a condensed sample if you condensed the air in an ambient room. The calculator DOES NOT use a psychrometric graph.

This calculator is an approximation for calculating the hydrogen peroxide in a condensed sample if you condensed the air from an ambient room. The calculator uses a psychrometric graph.

This calculator is to calculate the lactate concentration in a bioreactor where all the glucose is assumed to be converted to lactate.

This calculator is for converting from ppm to microMolar (microM) in the liquid phase.

This calculator is for converting from ppm to milliMolar (mM) in the liquid phase.

This calculator is for converting from microMolar (microM) to ppm in the liquid phase.
