Preparing Stock Solutions

The following data is based on the product molecular weight 277.34. Batch specific molecular weights may vary from batch to batch due to the degree 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 3.61 mL 18.03 mL 36.06 mL
5 mM 0.72 mL 3.61 mL 7.21 mL
10 mM 0.36 mL 1.8 mL 3.61 mL
50 mM 0.07 mL 0.36 mL 0.72 mL
