Reconstitution

Solution math,
done once.

Enter the labelled mass in the vial and the volume of diluent added. The calculator returns the resulting concentration, and the volume of that solution containing any given mass of peptide. Nothing is stored or transmitted — the arithmetic runs in your browser.

Research use only. This tool performs unit conversion on solutions. It is not dosing guidance, it does not suggest quantities, and none of the compounds listed on this site are approved for human or veterinary use.

Inputs

Values update as you type.

mg
As printed on the vial label.
mL
Bacteriostatic or sterile water, as added.
mcg
Mass you want to draw from the reconstituted vial.

Results

Rounded for display; full precision used internally.

Concentration — mg / mL

Equivalent in mcg/mL appears here.

Volume containing target mass — mL

Enter a target mass to calculate.

Aliquots of that size per vial — whole

Whole aliquots before the vial is exhausted.

The arithmetic

Concentration = mass ÷ volume
10 mg into 2 mL → 5 mg/mL, i.e. 5000 mcg/mL.
Volume = target mass ÷ concentration
250 mcg at 5000 mcg/mL → 0.05 mL.
1 mg = 1000 mcg
Vials are labelled in mg; aliquots are usually discussed in mcg.
Diluent volume is what you added
Lyophilized powder contributes negligible volume at these masses.
