Calculator

Enter the peptide mass and how much diluent you add. Get the concentration and the volume for any target mass.
mg
mL
µg
Concentration
5 mg/mL
Same as
5 µg/µL
Volume for target
50 µL

Formula: concentration = mass ÷ volume; required volume = target mass ÷ concentration. Example: 10 mg in 2 mL = 5 mg/mL, so 250 µg = 50 µL. For laboratory calculations only.

How it works

Lyophilized peptides are supplied as a dry powder. Adding a known volume of diluent, typically bacteriostatic water, gives a solution of known concentration: concentration (mg/mL) = peptide mass (mg) ÷ diluent volume (mL). Because 1 mg/mL equals 1 µg/µL, the volume needed for a target mass in micrograms is simply the target divided by the concentration.

Read our guide to reconstitution and storage of lyophilized peptides for diluent choice, aseptic technique and storage temperatures.
