Pure Proficiency’s Colony Enumeration Proficiency Assessment kit, by Pure Microbiology, is a proficiency test that provides an assessment without the use of live microbial samples and produces the third-party documentation needed to demonstrate proficiency in counting colonies. Use of the assessment can eliminate the potential for conflicting counts and take the guesswork out of assessing staff proficiency. Each plate used in the assessment is verified for accuracy before it is placed into circulation.
