Agar is prepared from a single species of red seaweed, specially selected for the preparation of a gel with stainless steel equipment. This agar has a relatively high content of mineral components and metals preferred for preparation of certain (but not all) of culture media.
Agar cream has a particle size of ASTM 40 which pass filter. When suspended in cold water agar swells but does not dissolve. Agar is readily soluble in boiling water, particularly in the case of pre-swelling in cold water.
