Merck, 1.46702, Sabouraud Dextrose Agar

General description
Sabouraud Dextrose Agar + LTHTh - ICR in 90 mm settle plates (lockable) is a selective media for the determination of the total count of yeasts and molds in air via active or passive air monitoring as well as fingerprints of personnel in isolators and clean rooms for sterility testing. Sabouraud Dextrose Medium contains digests of animal tissues (peptones) which provide a nutritious source of amino acids and nitrogenous compounds for the growth of fungi and yeasts. Dextrose is added as the energy and carbon source. The low pH favours fungal growth and inhibits contaminating bacteria from samples. Lecithin, polysorbate 80 (Tween®), histidine and sodium thiosulfate are neutralizers to inactivate residues of active agents such as Aldehyde, Biguanides, Oxidizing compounds, Phenolic compounds and quaternary ammonium compounds. In addition, the plate model (plus or “+”) is supplied with a lockable lid for safe transport after sampling without the risk of losing the lid as well as for aerobic incubation the plates should be locked in the “CLOSED”-position (turn the lid clockwise) and for anaerobic or microaerophilic incubation in the “VENT” position (turn the lid anti-clockwise)
Application
Sabouraud Dextrose Agar (SDA) is a selective medium for cultivation and isolation of yeasts and molds. The media finds its application in environmental monitoring by determining the yeast and mold count in air through active or passive air monitoring as well as fingerprints of personnel in isolators and clean rooms.
Preparation Note
The product can be used for sampling until the expiry date if stored upright, protected from light, and properly sealed at +15 °C to +25 °C.
Condensation can be prevented by avoiding quick temperature shifts and mechanical stress.
The testing procedures described on the CoA can be started up to the expiry date printed on the label.
