The total count of bacteria was estimated by the technique of photoelectric colorimeter
. (1) A comparative growth study for Staphylococcus Aureus was made using groundnut glucose broth and conventional glucose broth; while growth study of E.
For preparation of filtrate (after adsorption) and photometrical estimation of concentration of lead ions and copper ions in it we used a standard procedure with usage of photocolorimeter CPC (concentration photoelectric colorimeter
) -3-01 and spectrophotometer Spekord --50.
This exhibit includes a Klett Photoelectric Colorimeter
