Serial dilution is any dilution where the concentration is reduced by the same factor in each successive phase. For serial dilutions, multiply the dilution factors for each step. The dilution factor or dilution factor is the initial volume divided by the final volume. #DF = V_i / V_f # = # (1ml) / (10ml) = 1/10 #. This is a dilution of 1:10.

## How do you perform a serial dilution microbiology

The first step with serial dilutions is to take a known volume (usually 1 ml) of broth and add it to a known volume of distilled water (usually 9 ml). This gives 10 ml of diluted solution. This diluted solution contains 1 ml of extract per 10 ml, which is a 10-fold dilution. Also, what is Microbiology Diluent?

## Why is saline used in bacterial serial dilution?

In the case of serial dilutions or culture suspensions, physiological saline (Nacl) was used since the sodium chloride solution (Nacl) is isotonic in nature. In an isotonic solution, the solute concentration both inside and outside the microbial cell remains unchanged, and the cells remain at their usual osmotic pressure. But water is hypotonic in nature where the concentration of solutes inside the cell is higher than outside it, so the water tries to enter the bacterial cell.
