Peptide Reconstitution Calculator
Accurately calculate solution concentration and volume for laboratory preparation of lyophilized peptides. Designed for research environments requiring precision and consistency.
Accurate reconstitution is fundamental to reliable research outcomes. Use this calculator to determine the precise volume of bacteriostatic water needed for your vial, your concentration per millilitre, and the exact volume required per dose.

Reconstitution Guide
Bring the vial to room temperature
Before opening, allow the sealed lyophilized vial to sit at room temperature for 10–15 minutes. This reduces condensation and thermal stress on the peptide during reconstitution.
Wipe the rubber stoppers
Clean the rubber stopper of both the BAC water vial and peptide vial with a fresh alcohol wipe. Allow to air dry for 30 seconds before proceeding.
Draw the calculated volume of BAC water
Using a sterile insulin syringe, draw the volume of bacteriostatic water calculated above. Use the calculator at the top of this page to determine the correct amount for your desired concentration.
Use a U-100 insulin syringe for precise measurementInject slowly down the side of the vial
Insert the needle through the rubber stopper at an angle and inject the BAC water slowly down the glass wall of the vial — never directly onto the lyophilized peptide cake. This prevents foaming and preserves the peptide structure.
⚠️ Never inject directly onto the powderGently swirl — do not shake
Slowly rotate the vial between your fingers in a gentle circular motion until the peptide is fully dissolved. The solution should appear clear. Shaking or vortexing can degrade the peptide chain — always swirl.
Store immediately at 2–8°C
Once reconstituted, the solution should be refrigerated immediately at 2–8°C. Label the vial with the date of reconstitution. Use within 28 days for optimal research integrity.
