Fluid Thioglycollate Medium (FTM) is a critical component of our STERITEST® solution. The product has been formulated and tested to meet the requirements of the EP 2.6.1, USP 71, and JP 4.06. Our manufacturing approach ensures the highest level of quality for our media, improves accuracy and significantly reduces 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 fluid appears light yellow, slightly opalescent and viscous 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. The incubation temperature varies between 30-35°C, with an incubation time of 7-14 days. The product is supplied as 12 bottles of 100 mL of medium, screw cap with septum closure that reduces the risk of cross-contamination and growth inhibition.
Fluid Thioglycollate Medium (FTM) is primarily used for the detection of anaerobic bacteria. However, it also enables aerobic bacterial detection. The QC organisms include Clostridium sporogenes (ATCC 19404), Staphylococcus aureus (ATCC 6538) and Pseudomonas aeruginosa (ATCC 9027). This medium is used for sterility testing by membrane filtration or direct inoculation.
