What does this template do?
Calculate the concentration after each specified dilution step using transfer and diluent volumes.
Final volume equals transfer plus diluent volume. Dilution factor equals final volume divided by transfer volume, and final concentration equals stock concentration divided by that factor.
Concentrations use one consistent unit. Each row accepts its own starting concentration; link it to a previous result only when that step truly follows the prior dilution. Assumes additive volumes.
The working tab keeps editable inputs separate from formulas, with room for 60 records. The Notes tab explains the method and how to extend the range. All example records are fictional and can be replaced. Download a workbook format to retain formulas, or CSV when you need calculated values only.
What’s inside
- Final volume equals transfer plus diluent volume. Dilution factor equals final volume divided by transfer volume, and final concentration equals stock concentration divided by that factor.
- 60 prepared record rows with blank-row guards
- Blue input cells, typed dates and numbers, and frozen column headers
- Notes with the method, assumptions, and range-extension instructions

What formulas does this template use?
This template holds 182 formulas in 225 cells across 2 tabs, so 81% of its cells calculate. They use 6 distinct functions; the longest formula is 97 characters.
| Function | Uses | What it does |
|---|---|---|
IF | 481 | one result when a test is true, another when false |
COUNT | 180 | counts numeric cells |
OR | 60 | true when any test is true |
SUM | 60 | adds numbers |
COUNTIF | 2 | counts cells meeting one condition |
COUNTA | 1 | counts non-empty cells |
Counted from the workbook itself. Only functions that Excel, LibreOffice Calc, Google Sheets and Apple Numbers evaluate the same way are used, so the formulas survive every download format.
How do you use it?
- Replace the fictional records in blue cells with your own data. Keep the dark formula cells.
- Use the units stated in the column headers and keep each record on one row.
- Read the calculated columns and inspect the results before using them. Clear unused input rows; keep their formulas.
- The prepared range holds 60 records in rows 11–70. Extend formulas and summary ranges together if you add more rows.
What is it good for?
- Calculate the concentration after each specified dilution step using transfer and diluent volumes
- Replacing the labeled fictional records with your own figures
- Checking a calculation before adapting it to a larger workbook
Questions about this sheet
How is the result calculated?
Final volume equals transfer plus diluent volume. Dilution factor equals final volume divided by transfer volume, and final concentration equals stock concentration divided by that factor.
What assumptions should I check?
Concentrations use one consistent unit. Each row accepts its own starting concentration; link it to a previous result only when that step truly follows the prior dilution. Assumes additive volumes.
Can I add more than 60 records?
Yes. Copy the formula columns into new rows and extend every summary range to include them. Keep inputs and formulas in their original columns.
Are the example records real?
No. All example data is fictional and intended to demonstrate the formulas. Replace it before using the workbook for your own work.
