As agar is used only as a gelling agent in solid media, it is essential to avoid interactions with the rest of the media components such as meat extract, peptones, proteins, amino acids, sugars and other carbohydrates, as well as pigments, indicators, inhibitors, mineral salts, etc., used in their formulation. Secondly, the evaluation is frequently made without taking into account the characteristics of the agar obtained, or by comparing it only in some parameters (for instance with a bacteriological agar sample).

This consists of freezing and thawing the extract, previously gelled, and profiting from the insolubility of agar in the cold to eliminate the greatest part of the water contained in the extract. The speed of movement through the gel is then determined by the voltage gradient, i. e. the voltage between the electrodes. Comparative properties of hydrocolloids.
