Microorganism colonies transfer tool - comprising parallel bristles on carrier plate with handle, used for transfer from primary to selective media

摘要

Colonies of microorganisms, specially of prim. colonies which have grown up on a prim. nutrient medium, have to be transferred to several selective nutrient media during a culture differentiation and other biotechnical research. The primary colonies are picked up by applying to them a transfer tool with many independent adhesive elements, e.g. bristles, and by pressing the tool with the adhering cultures in turn on each of the sec. nutrient media. This creates a hygienically satisfactory method for primary colonies to selective nutrient media in which the same amt. is applied to each and in the same pattern.
