With a long time of expertise and one of the most thorough loved ones of diagnostic options, bioMérieux understands the difficulties struggling with dairy suppliers – and the constraints of these days’s checks. That is certainly why we developed AUGMENTED DIAGNOSTICS to detect, monitor and look into at each and every step with the minimal-humidity generation procedure. This permits for laboratory processes to become automated and to operate at an optimum amount, even though also becoming really Expense-effective.
By subjecting the products to a number of society media and incubation situations, sterility testing checks for any prospective contamination which could hurt patients.
