Fluid Thioglycollate Medium

Fluid Thioglycolate Medium contains thioglycollate and L-Cystine, which reduces the redox potential of the culture medium, creates an anaerobic atmosphere, and inactivates mercury and other heavy metal compounds. Agar reduces the rapid diffusion of oxygen but may lead to slight turbidity in larger volumes (filled bottles). Resazurin indicates the reduction potential of the medium. The color change of the medium to pink indicates an increased concentration of oxygen.

Fluid Thioglycolate Medium is used for the isolation and cultivation of fastidious anaerobic as well as for aerobic microorganisms. It is suitable for the sterility control of pharmaceutical products.

Our ready to use media provide the highest level of quality and testing confidence. They have been formulated and tested to meet the pharmacopoeia requirements. Sterility testing media and rinse solutions are manufactured in an ISO 9001, environmentally controlled production center. Each lot undergoes a stringent quality control (QC) procedure, including pH, sterility, and growth promotion tests. Our manufacturing approach ensures the highest level of clarity for our media and rinsing fluids, therefore improving accuracy and significantly reducing the risk of incorrect interpretation and false results.
