Bacteriological Agar

Our Bacteriological Agar is subjected to stringent quality control to ensure compatibility in culture media and is tested growing a wide range of fastidious micro-organisms.

Our Bacteriological Agar is free from extraneous matter, pigment portions and the salts have been reduced to a minimum. It is available as fine, light coloured granules, convenient for weighing and handling. It is normally employed in solid culture media at concentrations of 1 – 2%.

Our Bacteriological Agar is available in low, medium and high gel strengths and can be made to your specifications.

Standard Agar

This is a general purpose Agar that can be used for purposes that do not require stringent growth performances. It is available as low, medium, and high gel strength standard grade agar to match your specific requirements.

High Purity Agar

Our High Purity Agar is carefully processed to produce a high purity gelling agent with further reduced impurities.
This reduction of impurities reduces interferences while increasing effectiveness when employed in selective media.
