Product Description

Agar

Application Notes

Agar is used in microbiology and bacteriology to make solid culture media for microorganisms. According to the Merck Index, agar is typically used in: "Substitute for gelatin, isinglass, etc. in making emulsions including photographic, gels in cosmetics, and as thickening agent in foods esp. confectionaries and dairy products; in meat canning; in production of medicinal encapsulations and ointments; as dental impression mold base; as corrosion inhibitor; sizing for silks and paper; in the dyeing and printing of fabrics and textiles; in adhesives. In nutrient media for bacterial cultures".

Usage Statement

Research Use Only (RUO). Ready for CE IVD labeling of clinical applications.

Key Applications
