There are several methods of testing disinfectants, with their own advantages and disadvantages. Disadvantages of the Rideal-Walker test are: No organic matter is included; the microorganism Salmonella typhi Dilutions of the neutralizer are made and selected dilutions plated onto agar.
Advertisement Serial dilution A serial dilution is the stepwise dilution of a substance in solution. Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logarithmic fashion. A ten-fold serial dilution could be 1 M, 0.1 M, 0.01 M, 0.001 M. Serial dilutions are used to accurately create highly diluted solutions as well as solutions for experiments resulting in concentration curves with a logarithmic scale.

A tenfold dilution for each step is called a logarithmic dilution or log-dilution, a 3.16-fold (100.5-fold) dilution is called a half-logarithmic dilution or half-log dilution, and a 1.78-fold (100.25-fold) dilution is called a quarter-logarithmic dilution or quarter-log dilution. Serial dilutions are widely used in experimental sciences, including biochemistry, pharmacology, microbiology, and physics.

Advantage Of Serial Dilution Agar Plate Method The aim of broth and agar dilution methods is to determine the lowest concentration of the assayed antimicrobial agent (minimal inhibitory concentration, MIC) that. 1 Sterile spreaders are used to distribute inoculum over the surface of prepared agar plates. You can sterilise a wrapped glass spreader in a hot air oven. DIRECT MICROSCOPIC METHOD (TOTAL CELL COUNT) In the direct microscopic count, a counting chamber consisting of a ruled slide and a coverslip is employed.
