Clear Thioglycollate Medium, CTM Crimp cap with septum
Fluid Thioglycolate Medium (FTM) Clear is a universal complex medium, containing thioglycollate and L-cystine to reduce the redox potential, create an anaerobic atmosphere and inactivate mercury and other heavy metal compounds. The reduced agar content and the presence of a clear gelling agent to offer extra clarity. Resazurin indicates the reduction potential of the medium, while a color change from yellow to pink indicates an increased concentration of oxygen.
