Peptide Reconstitution
Calculator
A laboratory reference tool for calculating reconstitution volumes and concentration of lyophilized research peptides. Enter your vial specifications and target sample quantity to determine the correct solvent volume and measurement scale reading.
Quick-select by peptide
Click a peptide to automatically set vial amount & BAC water
Peptide amount in vial
As printed on the vial — e.g. 5 mg or 10 mg
Reconstitution solvent (BAC water)
More water = lower concentration per ml, easier to measure accurately
Target sample quantity (per measurement)
The quantity of compound per analytical sample — in micrograms (mcg). 1 mg = 1000 mcg
Graduated measurement vessel capacity
Select the volume capacity of your laboratory measurement vessel — U-100 scale (100 units = 1 ml)

How it's calculated
What is BAC water?
Bacteriostatic water (BAC) contains 0.9% benzyl alcohol as a preservative, allowing multiple draws from the same vial while inhibiting microbial growth.
U-100 graduated vessel
A U-100 graduated vessel has 100 units per ml — if you need 0.25 ml, measure to the 25-unit mark. The 0.5 ml / 50U format is standard for small-volume sampling.
Storage after reconstitution
Store reconstituted peptides refrigerated (2–8°C), protected from light. Use within 28 days. Keep unreconstituted vials in the freezer.
