This app is a user friendly tool for performing serial dilutions. The power in this app lies in the automation and flexibility. Users can choose to make up to 15 solutions selecting custom concentrations and volumes.

The tool automatically calculates the excess to make in order to have exactly enough remaining for your subsequent experiment. Simply type in your residual volume, and this tool will do the work.

Start with the highest concentration. You can use any of the more concentrated samples to make the more dilute samples; simply choose a Sample ID in the 3rd row and everything is automatically done. If you spill some sample, make the dilution with a different sample by changing the letter.

As long as all your units are the same, it doesn't matter if you are using milliliters or gallons, or tons or kg.

The calculate button is always visible, and the table is scrollable for convenience.

I'm a scientist, so I'll be using this often as well in my own lab.

Enjoy!
