Our professionals can incubate, enumerate and identify flora out of your environmental checking processes. Using a VITEK® two process to enrich conventional Gram stain and microscopy methods we are able to establish a vast library of environmental and scientific organisms to help in background environmental Examination, failure investigations, and contamination challenges.
