User Guidelines
The Colony Counting Calculator is designed for simplicity and ease of use. Follow these steps to calculate CFU/mL:
- Step 1: Enter the number of colonies counted on the agar plate in the first input field.
- Step 2: Enter the dilution factor used for the sample (e.g., 100 for a 1:100 dilution) in the second input field.
- Step 3: Enter the volume of the sample plated (in milliliters) in the third input field.
- Step 4: Click the "Calculate CFU/mL" button to obtain the result.
The calculator uses the formula: CFU/mL = (Number of Colonies × Dilution Factor) / Volume Plated. Ensure all inputs are positive numbers, with the dilution factor being at least 1 and the volume plated greater than 0. The result represents the concentration of viable microorganisms in the original sample, expressed as CFU/mL.
