Research Tools:
Peptide Calculator
Turn vial strength, solvent volume and the amount you need into a stock concentration and a transfer volume in mL and µL. For in vitro laboratory use.
Concentration & Dilution Calculator
Enter the peptide weight in your vial, the water you added and the amount you need. The calculator works out the stock concentration and how much solution to transfer, in mL and microlitres.
A laboratory maths tool only. It simply converts the figures you enter. It does not suggest a solvent, concentration, sample size or method of use, and it is not dosing, medical or veterinary guidance.
Transfer volume
0.2mL
- Stock concentration
- 5mg/mL
- Amount needed

Research use notice. This calculator is a general maths tool for laboratory research. It gives no dosing, administration or medical guidance. Crown Peptides products are supplied for in vitro laboratory research only and are not for human or veterinary use. Researchers are responsible for checking their own calculations and the legal requirements that apply to their work.
How this calculator works
Concentration
The peptide weight divided by the water added. A 10 mg vial in 2 mL gives a 5 mg/mL stock solution.
Transfer volume
The amount needed divided by the stock concentration, which gives the transfer volume in millilitres.
Microlitres
1 mL is 1,000 µL, so 0.2 mL is 200 µL. Transfer volumes are shown in both.
About this calculator
What it works out
The stock concentration and transfer volume, calculated purely from the peptide weight, water volume and amount you enter.
What it does not do
It does not recommend any amount, concentration, solvent or procedure. Every figure comes from you, the researcher.
Check your results
Always check results against your own laboratory procedures. 1 mg is 1,000 µg, and 1 mL is 1,000 µL.
