Gelling agent essentially free of impurities. Used mainly in biochemistry and molecular biology procedures wherever increased purity is required.
Typical Agar Preparation:
Autoclave for 20 minutes and swirl gently to evenly distribute the agar. If antibiotics are to be added, allow the agar to cool to 50°C. When pouring plates, gently swirl the medium. A Bunsen burner flame can be passed over the surface of the plates to remove any air bubbles. After the medium has hardened, invert the plates and store at 4°C.
