    Agar agar
    Agar is the dried, hydrophilic, colloidal substance extracted from algae known as Agarophytes (several species and genera of the Class Rhodophyceae). It consists of two polysaccharides, agarose and agaropectin, in a variable proportions depending on the geographical zone of origin. Agar-Agar is a solidifying agent with almost the same gelling strength as the Bacteriological Agar but with less purification. It has greater opacity and has a higher salt content. Its use in culture media is recommended only when transparency and clarity is not a critical requirement. The most important characteristics are: Physical data Melting point 85 ± 5 ºC Gelling point 35 ± 5 ºC Gel strength (Nikan) 750 ± 50 g/cm2 Dissolution time (at 100ºC) 1,00 min Turbidity < 36 NTU Chemical data pH of 1,5% solution at 25ºC 6,9 ± 0,1 Particle size < 0,3 mm Loss on drying < 19,0 % (w/w) Residue on ignition 6,5 % (w/w) Acid insoluble ash < 0,5 % (w/w) Note: Data are average values, which may vary from batch to batch.
