1 Thoroughly disperse the agar in cold 75% seawater. Bring to the boil, stirring continuously. During heating add the other constituents. Transfer the molten agar to suitable vessels and sterilise at 15 psi for 15 minutes. If available a bench top agar maker is preferable to making this medium. The constant stirring during sterilisation minimises flocculation.
