General description

Modified Tween®-Letheen Broth has a significantly improved nutritional content when compared to the Letheen-Broth. This has higher meat peptone concentration along with casein and yeast extract vitamin sources.
Addition of sodium thiosulfate (neutralizes iodine and chlorine) and sodium bisulfite (neutralizes formaldehyde, formaldehyde releasers and Glutaraldehyde) has improved the efficacy of the inactivating agents.

Application

Modified Tween®-Letheen-Broth is designed for the enumeration of fastidious microorganisms in the presence of disinfectant residues.

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 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.
