How It Works
This generator works in 4 steps.
Enter the series parameters
Type the starting concentration, factor, transfer volume, and tube count.
Choose the layout
Select a horizontal row, a vertical column, or a plate view.
Style the labels
Show or hide volumes, concentrations, DF, and exponent notation.
Export the diagram
Download SVG or PNG, or copy it to the clipboard.
The Formula
The formula labels each tube with the starting concentration divided by the factor raised to the tube number.
Cₙ = C₀ / FⁿV_t = V_d / (F − 1)shade ∝ log₁₀(Cₙ)- C₀:
- Starting concentration
- F:
- Factor per step
- V_t / V_d:
- Transfer and diluent volumes
A tenfold series from 1,000 µg/mL with 100 µL into 900 µL draws 5 tubes labeled 100, 10, 1, 0.1, and 0.01 µg/mL.
Conversion Table
The conversion table lists the labels the generator places on a 5-tube tenfold diagram from 1,000 µg/mL.
| Position | Arrow label | Diluent | Tube label | Flow |
|---|---|---|---|---|
| Stock | — | — | 1,000 µg/mL | Source |
| Tube 1 | 100 µL from previous | 900 µL | 100 µg/mL | → next tube |
| Tube 2 | 100 µL from previous | 900 µL | 10 µg/mL | → next tube |
| Tube 3 | 100 µL from previous | 900 µL | 1 µg/mL | → next tube |
| Tube 4 | 100 µL from previous | 900 µL | 0.1 µg/mL | → next tube |
| Tube 5 | 100 µL from previous | 900 µL | 0.01 µg/mL | End |
What Is the Serial Dilution Diagram Generator?
The Serial Dilution Diagram Generator is a tool that draws a labeled diagram of a serial dilution, with tubes, transfer arrows, volumes, and the concentration in each tube. The diagram updates as the user changes the factor, volume, or tube count.
A diagram shows the transfer path at a glance, so it suits bench sheets, lab reports, and teaching slides. The generator colors tubes by concentration, labels each arrow with the transfer volume, and exports SVG for editing or PNG for documents.
Common Uses
There are 5 main uses of this generator.
Lab reports
Students add method diagrams to reports.
Teaching slides
Instructors show serial dilution steps in lectures.
Bench sheets
Technicians print the diagram above the tube rack.
SOP figures
QA teams add standard diagrams to SOPs.
Grant and paper figures
Researchers prepare method schematics.
