Skipping necessary measures which include drinking water trials or conducting leak tests soon after interventions can cause surprising problems in the course of media fill.
To overcome the constraints of the normal sterility testing strategies, we provide immediate sterility testing applying totally automatic microbial detection technological innovation.
