Preparing Stock Solutions

The following data is based on the product molecular weight 358.54. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.79 mL 13.95 mL 27.89 mL
5 mM 0.56 mL 2.79 mL 5.58 mL
10 mM 0.28 mL 1.39 mL 2.79 mL
50 mM 0.06 mL 0.28 mL 0.56 mL

Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / CoA (available online).

Reconstitution Calculator

The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.


Dilution Calculator
