Full-automatic Ames experiment instrument

Abstract

The invention provides a full-automatic Ames experiment instrument. The full-automatic Ames experiment instrument comprises a culture dish storing and transferring system, a test tube transferring system and a sample adding system, wherein the culture dish storing and transferring system is configured in a manner that culture dishes are withdrawn one by one, so that a culture dish cover and a culture dish body of each withdrawn culture dish are separated, the culture dish bodies are transported to stations of the culture dishes, the separated culture dish bodies are covered by the culture dish covers, and the reintegrated culture dishes are placed in an accommodating cavity; the test tube transferring system is configured in a manner that test tubes are respectively moved to each scheduled test tube station, and substances in the test tubes are separately poured in each culture dish body in a corresponding dumping station; and the sample adding system has a plurality of storage containers, and is configured in a manner that the substances in the storage containers are transported to each test tube, so that each test tube receives at least two substances. Through the adoption of the full-automatic Ames experiment instrument disclosed by the invention, the culture dishes can be automatically transported to the scheduled positions, and the test tubes and the substances are automatically selected; and the reagents are added to the test tubes, and the mixed reagents are transported to the culture dishes, so that the Ames experiment is automatic, the experiment efficiency and the experiment precision are improved.

Description

technical field [0001] The invention relates to the technical field of Ames experiment, in particular to a fully automatic Ames experiment instrument. Background technique [0002] After more than ten years of hard work by B.N.Ames et al., the Salmonella reverse mutation experiment (also known as Ames experiment, Ames experiment) established and continuously developed in 1975 has been widely adopted by countries all over the world. This method is fast, simple, sensitive and economical, and is suitable for testing mixtures, reflecting the comprehensive effects of various pollutants. Ames test can be used to detect the mutagenicity of food additives, cosmetics, etc., and thus its carcinogenicity can be inferred; Ames test can be used to detect the mutagenicity of water source water and drinking water, to explore more hygienic and safer disinfection measures than the current method; or to detect urban The mutagenicity of sewage and industrial wastewater, combined with chemical...

AI Technical Summary

Problems solved by technology

In the existing Ames experiment, the experimenter uses a dropper to add reagents to the petri dish. The degree of automation is low and the labor cost is high. Although it can guarantee a certain accuracy of the experiment, it will also lead to huge deviations in the experimental results due to human error.
