R2A-NPS

R2A-NPS are used for the total colony count of mesophilic, heterotrophic microorganisms in water and other samples. R2A-NPS is a medium with low nutrient concentration, which, in combination with the long incubation time at low incubation temperature, allows slow growing organisms to develop without being suppressed by fast growing organisms. The medium is manufactured and quality tested in compliance with ISO 11133:2014 standard.
