Peptide Reconstitution Calculator

Use this peptide reconstitution calculator to estimate peptide concentration and approximate U-100 units after adding diluent to a lyophilized vial.

This tool allows you to quickly calculate how much volume corresponds to a specific research aliquot based on vial size and dilution. Simply enter the peptide amount, the volume of diluent added, and your target amount to generate an accurate estimate.

Designed for accurate peptide concentration and measurement estimation using standard U-100 units.

How to Use the Peptide Reconstitution Calculator

1. Select the peptide amount in the vial (in milligrams).
2. Choose the volume of diluent added (in milliliters).
3. Select or enter your target research aliquot amount.
4. The calculator will display the approximate U-100 equivalent based solely on the concentration and values entered.

Custom values can be entered by selecting “Other” for any field.

Understanding Peptide Reconstitution

Peptide reconstitution refers to the process of adding a liquid, to a lyophilized (freeze-dried) peptide in order to create a usable solution for laboratory research.

Once reconstituted, the peptide forms a solution with a defined concentration. This concentration determines how much volume corresponds to a given amount of peptide.

Accurate reconstitution is important for consistency in measurement and repeatability in research environments.

Peptide Concentration Explained

Peptide concentration is calculated by dividing the total peptide amount (in milligrams) by the volume of diluent added (in milliliters), resulting in a concentration expressed as mg/mL.

For example, a 10 mg peptide vial reconstituted with 2 mL of diluent results in a concentration of 5 mg per mL.

This calculator automatically performs these conversions and translates the result into U-100 units for convenience.
