Agar (bacteriology grade) is a polysaccharide extracted from seaweed, widely used as a culture medium in microbiology for bacterial and fungal growth. It solidifies at room temperature and liquefies when heated, making it ideal for petri dishes, slants, and plates. This product has a CAS number of 9002-18-0 and the molecular formula (C12H18O9)n. It requires no special storage conditions and carries no signal word. Molekula supplies Agar (bacteriology grade) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
