Can the QuickTest, QT Junior or QTMicro be used to detect microbial contamination in antibiotics?
Yes. The biggest concern is reducing the concentration of residual antibiotic agents in the tester’s fluid path to a level where it does not interfere with culturing possible microbiological contaminates. USP suggests rinsing the filter sufficiently to remove these trace amounts of antibiotic agents. QuickTest’s and QT Junior’s unique design of the filter helps the rinsing process. The filter membrane is held in the plastic support by insert molding. During manufacturing, molten plastic fills the microscopic pores around the filter’s edges. Filling these pores prevents residual traces of antibiotics from being trapped in the filter’s edge during rinsing.
