Method and device for culture medium inoculation by using gravity to control strength

Abstract

The invention relates to a method and a device for culture medium inoculation by using gravity to control strength. The device comprises a rotary inoculation tray and is characterized in that the rotary inoculation tray is provided with a plurality of inoculation ring mechanisms; each inoculation ring mechanism comprises an inoculation ring and a pin shaft; the inoculation ring penetrates into the pin shaft; the pin shaft is fixed in a fixed base of the inoculation ring; the fixed base of the inoculation ring is fixed on the rotary inoculation tray. The device disclosed by the invention is compact in structure, has the functions of sampling, inoculation and sterilization and has the main characteristics that the inoculation ring adopts a gravity method, an inoculation end of the inoculation ring is attached to the surface of a culture medium by eccentric weight of the inoculation ring, the culture medium is not damaged and failed inoculation of the culture medium is prevented, so the device provides a brand-new automatic inoculation method.

Description

(1) Technical field [0001] The invention belongs to the inoculation technology, and in particular relates to a culture medium inoculation method and device using gravity to control force. (2) Background technology [0002] At present, in the microbial industry, the bacterial inoculation of solid medium is mainly done manually, and its operating specifications and biological safety cannot be effectively guaranteed. In the last two years, the French Mérieux Biological Company and the German Siemens Company have launched their own automatic inoculation products to the market, which have been welcomed and recognized by the market, but some problems have also been exposed in the process of use, in which the surface of the culture medium is demarcated. Breaking and samples not being inoculated on the surface of the culture medium are the most important problems. The reasons are mainly in two aspects: the first is that the inoculation loop is bent and deformed after repeated high-t...

Problems solved by technology

[0002] At present, in the microbial industry, the bacterial inoculation of solid medium is mainly done manually, and its operating specifications and biological safety cannot be effectively guaranteed.

In the last two years, the French Mérieux Biological Company and the German Siemens Company have launched their own automatic inoculation products to the market, which have been welcomed and recognized by the market, but some problems have also been exposed in the process of use, in which the surface of the culture medium is demarcated. Breaking and samples not being inoculated on the surface of the culture medium are the most important problems. The reasons are mainly in two aspects: the first is that the inoculation loop is bent and deformed after repeated high-temperature sterilization during long-term work; The difference between the culture dish and the medium makes the surface height of the medium inconsistent, so the strength of the inoculation loop applied to the surface of the medium is also inconsistent, so it is easy to miss the medium or scratch the medium
