The invention relates to medicine and biotechnology and can be used for more qualitative selection of biomaterial as component of identification by method of extraction of microorganisms MALDI-and-TOF mass - spectrometry. Proposed version of the device for collection of colonies of microorganisms with surface of dense nutrient media, is a forceps, non structure, in upper part of pincers is handle for gripping fingers, which along the whole width is equipped with cylindrical slots for more convenient holding forceps fingers; in lower part of pincers on rear pedicle is thrust screen, in lower part of pincers on front pedicle is "boot", in section which is a triangle, for collection of crops with surface of dense nutrient media, creating lifting "sapozhka" in 18?7 ' , all part of device are made from polypropylene or polypropylene homopolymer, in process of manufacture is allowed application thereof modifier for ny to increase the properties of elasticity and impact resistance. This utility model allows qualitatively taken vrosshie and come on the surface of nutrient media colonies. 1 dwg.
