Agar-Agar, BioScience, BioScience-Grade, powdered, 250 g, plastic

Agar-Agar, BioScience is a BioScience-Grade powdered gelling agent for microbiological media, molecular biology workflows and general laboratory culture work. It is identified by CAS number 9002-18-0 and EG nr. 232-658-1, providing a clear regulatory and catalogue identity for reagent documentation. Supplied as a free-flowing powder Agar-Agar from manufacturer Carl ROTH is positioned for BioScience applications where consistent gelling performance and straightforward handling are required. The powdered form dissolves under standard heating and preparation conditions used in media kitchens and research laboratories, allowing flexible batch sizes from. Categories linked to genetic engineering and virus-related research underline its role as a basic matrix component rather than a specialised active reagent. Laboratories can incorporate this BioScience-Grade agar into established recipes for nutrient agar, selective media and support gels while keeping pack size and chemical identifiers aligned with inventory and quality systems. The plastic packaging supports clean storage and repeated dispensing in daily laboratory use.
