Agar-Agar, BioScience is a BioScience-Grade granulated gelling agent supplied for microbiological media, molecular biology and related laboratory culture applications. Identified by CAS number 9002-18-0 and EG number 232-658-1, this agar supports preparation of solid and semi-solid media used in genetic engineering, virus research and general life-science workflows where consistent gel formation is required. The material is delivered as free-flowing granules BioScience-Grade quality from manufacturer Carl ROTH is positioned for research and routine laboratory use rather than industrial bulk processing. Typical applications include plate and tube media for microbial growth, overlay gels and other bioscience formulations that depend on reliable agar performance. The granulated form dissolves under standard heating protocols familiar to media kitchens and research laboratories. This pack size is convenient for teaching labs, core facilities and research groups that prepare culture media on a regular basis.
