Preparing Stock Solutions

The following data is based on the product molecular weight 1555.98. 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 0.64 mL 3.21 mL 6.43 mL
5 mM 0.13 mL 0.64 mL 1.29 mL
10 mM 0.06 mL 0.32 mL 0.64 mL
50 mM 0.01 mL 0.06 mL 0.13 mL
