Peptide Calculator

Enter the desired mass per research sample, the lyophilised solid mass and the diluent or solvent volume added. The calculator will show the sample count and liquid volume for each sample.

Calculator details

Enter numbers greater than zero. Your results update automatically.

1. Desired Mass/Concentration per Sample Target solid mass for each research sample

2. Lyophilised Solid Mass Total solid mass shown on the vial

3. Diluent/Solvent Volume Total liquid volume added

How the calculation works

1. Number of samplesTotal lyophilised solid mass ÷ desired mass per sample.

2. Volume per sampleTotal diluent or solvent volume ÷ theoretical number of samples.

3. U-100 markingVolume per sample in mL × 100.

Important: Results are estimates only. Small differences can happen because of product purity, liquid lost during transfer, measuring tools and handling. U-100 syringe markings are shown only as a calibrated liquid-volume reference for laboratory measurement. Always check your calculations and equipment. For research use only.
