Description

General description

Fluid Thioglycollate Medium (FTM) Clear is a complex medium suitable for the cultivation and isolation of fastidious aerobic and anaerobic microorganisms during sterility testing of pharmaceutical products. The reduced agar content supplemented by a clear gelling agent offers extra clarity with the same media properties as FTM.

Application

Fluid Thioglycollate Medium (FTM) Clear is used as a sterility testing medium for sterile pharmaceutical products. FTM clear is used to cultivate and isolate anaerobic and microaerophilic microbes.

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.

Principle

Thioglycollate and L-Cystine reduce the redox potential of the culture medium to create an anaerobic atmosphere. Additionally, these agents inactivate mercury and other heavy metal compounds. Agar and clear gelling agents further reduce the rapid diffusion of oxygen through the medium while offering a clear medium. Resazurin indicates the reduction potential. A color change from yellow to pink in the medium shows an increase in oxygen concentration.

Analysis Note

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