Serial dilution of water sample
WebThe liquid sample is directly used as homogenous suspension of bacteria. The suspensions of bacteria so obtained are diluted serially (10 times, 100 times, 1000 times etc.). Here 10 -1, 10 -2, 10 -3 etc. are called dilutions. ADVERTISEMENTS: Their reciprocals (10 1, 10 2, 10 3 etc.) are called dilution factors.
