Agar Granulated (MB029)

115,00187,00

Clear

Description: Purified agar with excellent properties for tissue culture and microbiological work. The granulated presentation allows convenient weighing and handling without the mess of powders. Agar is a natural hydrocolloid extracted from several species of red algae, mainly the Gelidium, Gracilaria and  Pterocladia types. It is a gelling agent used in the preparation of culture media and other bacteriological applications.
The main advantage of this agar is the absence of inhibitors, which could interfere in microorganisms´ growth. It has excellent transparency, high hysteresis and very reliable reproducibility. Each batch produced is thoroughly tested for biological performance against a battery of known bacterial cultures in order to ensure proper growth characteristics and absence of inhibitors.
