Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
