Clear Thioglycollate medium has the same growth promotion properties as the standard Fluid Thioglycollate Medium (FTM). The alternative formulation brings extra visual clarity versus the FTM which has a slight turbidity or haze. Composition and growth performance of this medium comply with the European Pharmacopeia (EP) 2.6.1, United States Pharmacopeia (USP) 71 and Japanese Pharmacopeia (JP) 4.06. Our manufacturing approach ensures the highest level of quality for our media, improving accuracy and significantly reducing the risk of incorrect interpretation and false results. The sterilized double Tyvek^® packaging allows to streamline the cleaning procedures, to minimize the risk of cross-contamination in laminar flow hoods and to secure an efficient decontamination of isolator chambers. The appearance of the fluid is light yellow and viscous liquid with a pink ring in suspension ≤1 cm. The pH of the product is 7.1 ± 0.2 and can be stored at 2-25°C for 12 months. The incubation temperature varies between 30-35°C, with an incubation time of 7-14 days. One box of product contains 12 bottles of 100ml of Medium. Each bottle has a screw cap with a septum that minimizes the risks of cross-contamination and optimizes the disinfection procedures.

Clear Fluid Thioglycollate Medium is intended for the detection of anaerobic bacteria however, it also enables aerobic bacterial detection. This medium is used for sterility testing by membrane filtration or direct inoculation. The QC organisms include Clostridium sporogenes (ATCC 19404), Staphylococcus aureus (ATCC 6538) and Pseudomonas aeruginosa (ATCC 9027).
