Rw. Jackson et al., Multiregional evaluation of the SimPlate heterotrophic plate count method compared to the standard plate count agar pour plate method in water, APPL ENVIR, 66(1), 2000, pp. 453-454
A new SimPlate heterotrophic plate count (HPC) method (IDEXX Laboratories,
Westbrook, Maine) was compared with the pour plate method at 35 degrees C f
or 48 h. Six laboratories tested a total of 632 water samples. The SimPlate
HPC method was found to be equivalent to the pour plate method by regressi
on analysis (r = 0.95; y = 0.99X + 0.06).
