PREPARED GROWTH MEDIUM For Use With Geobacillus stearothermophilus.
The prepared growth media consists of an exclusively formulated Tryptic Soy Broth (TSB) modified with pH indicator. The pH indicator causes a transition in media colour from purple to yellow when Geobacillus stearothermophilus bacterial growth is present, allowing for a reduced incubation when used in conjunction with Excelsior Scientific’s Biological Indicators (BIs) and Inoculated Carriers.
The GMBCP growth medium is designed to be utilised in conjunction with BIs containing Geobacillus stearothermophilus to monitor Steam at 121°C to 137°C, Vaporised Hydrogen Peroxide (VH2O2), & Formaldehyde processes.
