METHOD FOR OBTAINING STANDARD SPECIMEN OF TURBIDITY OF BACTERIAL SUSPENSIONS, STANDARD SPECIMEN OF TURBIDITY OF BACTERIAL SUSPENSIONS, ITS USE, SET CONTAINING STANDARD SPECIMEN OF TURBIDITY OF BACTERIAL SUSPENSIONS

摘要

FIELD: biotechnologies.SUBSTANCE: invention proposes a method for obtaining a standard specimen of turbidity of bacterial suspensions, a standard specimen of turbidity of bacterial suspensions, use of the standard specimen of turbidity of bacterial suspensions, as well as a set containing the standard specimen of turbidity of bacterial suspensions. The method involves shuttling of chemically neutral borosilicate glass without any carbon dioxide bubbling in presence of thiomersal during 10-70 days. Shuttling is performed in a shaking mode with at least 50-60 oscillations per minute for 5-6 hours a day at oscillation amplitude of at least 5 cm. After shuttling is completed, the obtained suspension is subject to sedimentation for removal of particles with the size of more than 3.5 mcm and less than 0.5 mcm. The standard specimen of turbidity of bacterial suspensions includes a micro suspension of chemically neutral borosilicate glass with the particle size of 0.5-3.5 mcm; with that, content of particles of this fraction is at least 95%.EFFECT: inventions allow simplifying a method for obtaining a standard specimen of turbidity of bacterial suspensions and simultaneous improvement of stability of the standard specimen.4 cl, 2 dwg, 2 tbl, 8 ex
