Description
Technical Field
The utility model relates to a biological assay field, especially a bacterial count report auxiliary device.
Background
The bacterial count report is a common practice in laboratories and is often used to determine whether the number of microorganisms in a unit sample meets the specifications. After the existing common method is finished, the number of colonies is visually observed, an appropriate dilution grade is selected, then the specific number of the colonies is reported, and finally the total number of the colonies is obtained by multiplying the specific number by the dilution grade. In the process, colonies formed by different microorganisms are different in size, and the determination of the dilution level is determined according to different conditions, for example, the total aerobic count is preferably determined by selecting the dilution level with the average colony count of less than 300 CFU; mould and yeast gross determination should select the dilution level that average colony number is less than 100CFU, however, because colony number on the flat board through the cultivation is more, only easily produce the error by the visual observation, and after confirming the dilution level, when reporting specific colony number, when colony number is more, if there is not some auxiliary tool, also can bring some troubles for the report, consequently, for the selection dilution level that is more swift when carrying out the bacterial number report, convenient follow-up observation and count simultaneously, need a bacterial number report auxiliary device urgently in the biological assay field.
