Agar Agar (Laboratory Grade)

The Agar Agar (Laboratory Grade) is a natural polysaccharide extracted from marine algae, used as a solid gelling agent in laboratory routines, mainly for the preparation of microbiological culture media and analytical procedures requiring stable gel formation. It forms a consistent gel after dissolution in hot water followed by cooling, enabling solid support matrices for culture media and semi-solid systems. This product functions exclusively as a gelling agent and does not contain nutrients or selective components.
