Bacteriological Agar
for Microbiology

Global BioIngredients represents over 70 years of knowledge and experience in agar production. By controlling every step of production from raw material collection, through manufacturing, to packaging and distribution, Global’s factories set the industry standard for quality and supply chain reliability while controlling costs in a volatile market.

All bacteriological and technical grade agars offered by Global BioIngredients are manufactured from the Gelidium species of seaweed. Exclusive use of Gelidium insures higher gel strength, greater optical clarity, and consistent lot to lot purity and performance. Our factories are unique in the industry in their ability to control both raw material collection and the manufacturing process. By carefully maintaining worldwide coastal harvesting and collection rights we can protect our customers from the volatility of raw material pricing and shortages on the open market. Global BioIngredients offers a number of different agars to match every application and price point.

Name Description

Bacteriological Agar (Hispanagar)

Bacteriological Grade is manufactured from a narrowly selected variety of Gelidium that produces a bacteriological grade agar second to none in its ability to support the growth of a wide variety of both fastidious and non-fastidious organisms. For decades our agar has been, and continues to be the gold standard by which other agars are measured.

Bacteriological Agar (Agarmex)

An alternative bacteriological grade agar manufactured from seaweed harvested exclusively from the Pacific waters of North America.

Bacteriological Agar, PH

Pharmaceutical Agar is manufactured using a freeze-thaw extraction process, making it one of the purest forms of general purpose agar available

Bacteriological Agar, High Gel

High Gel Agar offers the same quality as our bacteriological grades but is manufactured for applications requiring unusually high gel strength.

Technical Grade Agar

Technical Grade Agar is a cost effective agar appropriate for a wide range of applications.

Purified Agar (Noble Agar)

Purified Agar, equivalent to Noble Agar, is a very highly purified specialty agar, practically clear and devoid of any nutritive value or reactive properties by design. Purified agar is typically employed in immunodiffusion studies as well as in the animal and plant cell culture fields.
