MICROBIAL LIMIT TESTS This chapter provides tests to the estimation of the volume of viable aerobic microorganisms present and for liberty from selected microbial species in pharmaceutical content of all kinds, from raw materials on the completed kinds. An automatic method could be substituted for that tests introduced in this article, supplied it's been correctly validated as supplying equal or much better results.
