After mixing, the diluted solution can be stirred if there are large particles. If the 1:9 dilution is too viscous, the volume of the diluent can be increased. If a concentration higher than the 1:9 first dilution is required to obtain experimental results, the volume of the diluent can be appropriately reduced. If the estimated number of bacteria in the sample is less than 10 CFU/g, the first dilution shall be used. If the bacterial content is lower, the volume of the dilution can be appropriately reduced. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
