Description

General description

Fluid Thioglycollate Medium (FTM) with 0.5% Tween^® 80 is a complex medium. Thioglycollate and L-Cystine reduce the redox potential of the culture medium and create an anaerobic atmosphere, along with inactivating mercury and other heavy metal compounds. The presence of agar reduces a rapid diffusion of oxygen through the medium but may lead to slight turbidity in larger volumes (filled bottles). Resazurin indicates the reduction potential of the medium. An increased concentration of oxygen is indicated by a color change to pink. The polysorbate (Tween^®) 80 also assists in the suspension of hydrophobic substances. It further serves to neutralize disinfectants such as quaternary ammonium compounds, iodine, and parabens.

Application

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

Features and Benefits

Our ready-to-use media provide the highest level of quality and testing confidence. They have been formulated and tested to meet the pharmacopeia 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, thus improving accuracy and reducing the risk of incorrect interpretation and false results.

Analysis Note

The appearance of the medium is clear or almost clear and yellowish.
