CompositionFormula per liter of medium: Peptone from Casein 15.00 gm; Meat Extract 4.50 gm; Glucose 7.50 gm; Sodium Chloride 7.50 gm; Sodium Azide 0.2 gm; Agar 15.00 gm. Final pH (at 25°C) 7.0 ± 0.2. ** Formula adjusted, standardized to suit performance parameters.
PreparationSuspend 49.7 g of the powder in 1 L of purified water. Autoclave at 121°C for 15 minutes. On repeated exposure to air and absorption moisture sodium chloride has tendency to form lumps, therefore we strongly recommend storage in tightly closed containers in dry place away from bright light.
StorageBioScien Azide Dextrose Agar Stored between 15-30°C in a tightly closed container and the prepared medium at 2-8°C. Use before expiry date on the label. On opening, product should be properly stored dry, after tightly capping the bottle in order to prevent lump formation due to the hygroscopic nature of the product. Improper storage of the product may lead to lump formation. Store in dry ventilated area protected from extremes of temperature and sources of ignition. Seal the container tightly after use. Product performance is best if used within stated expiry period.
AppearanceThe color of BioScien Azide Dextrose Agar is Beige, free-flowing, homogeneous. Prepared media is Light amber, clear to very slightly opalescent. If there are any physical changes for powder or signs of deterioration (shrinking, cracking, or discoloration), and contaminations for hydrated media, discard the medium.
