Why do microbial limit test methods validate?

Why do microbial limit test methods validate? Today, the Xiaobian of Zhuorui Scientific Instrument Co., Ltd. will introduce this problem to you. I hope it can help you.

  1. Contaminated microorganisms in drugs are in an unstable state, and the species of microorganisms are uncertain.

  2.in each link of drug production, microbial pollution is not uniform.

  3.both without antimicrobial drugs and antibacterial drugs to microbial limit inspection, especially the pollution in the antibacterial drugs microorganism under certain conditions can be stable in a period of time, microbial limit tester, though they may damage, but not killed, such as taking to the human body, can still grow when conditions suitable.

  4.Some drugs present bacteriostasis under test conditions and interfere with the detection or counting of the bacteria to be tested. However, when they are diluted by gastric and intestinal fluids, the bacteriostasis is weakened or injected directly into the blood intravenously, the bacteria can recover and multiply, causing harm to the human body.

  5.Any bacteriostatic drug has a certain bacteriostatic range, that is, the antibacterial spectrum. A considerable number of antimicrobial drugs have no effect on fungi. Drugs that are sensitive to all types of bacteria are almost non-existent.

  6.bacteria have adaptability to antimicrobial drugs, drug resistance of pathogenic strains are common in clinic, so is possible within the antibacterial drug of microbes and can cause harm to human body health, so of antibacterial drugs is also necessary for microbial limit inspection, but bacteriostatic drugs in the inspection process will have obvious bacteriostatic action, Microbial limit tester This greatly affects the detection of microorganisms.

  With these verification conditions, the verification test can be carried out

  1. Facilities, equipment, instruments and materials for verification experiments;

  2. Diluent (liquid) and rinse solution for verification test;

  3. Treatment methods of antibacterial samples;

  Medium dilution method: this method is generally suitable for the test products with not very strong bacteriostatic effect.

  Since its establishment, Zhuorui Craftsman Scientific Instrument (Shanghai) Co., Ltd. has established a long-term stable supply and marketing relationship with some domestic large enterprises, such as Shuanghui, Huying, Zhongpin, Pingmei, Sanquan, Yisai, Anjing, White Elephant Food, Master Kong, Jinmailang, Yili, Mengniu. The "Yirui brand" of the company has complete specifications and various varieties of instruments, which can meet the different needs of experiments, laboratory tests and analysis in various industries. In the choice of the company, we must find the quality of the manufacturer, the company is a company with many years of experience, in this respect the quality is guaranteed, so if you need, might as well contact us to understand, I believe must be a good choice.
