Antibacterial mechanism and applicable strains Phenoxyethanol has broad-spectrum bacteriostasis, and its antibacterial mechanism is to act on the cell membrane, improve the permeability of the cell membrane to potassium ions, and inhibit the enzymatic activity (such as malate dehydrogenase) required for cell growth. Phenoxyethanol has specific bacteriostatic activity against Pseudomonas aeruginosa, and also has bacteriostatic effect on Gram-positive and negative bacteria.

The tense situation in Ukraine and Russia, the severe epidemic situation, the high level of crude oil and the surge in natural gas have all turned into "thunders" in the trend of chemical products, driving the rise of chemical products fiercely. However, the price increase of chemical fungicides has been announced silently, whether you are a product in the crude oil industry chain or not, whether you are directly affected by geopolitical conflicts and force majeure, it will not affect the "one-pot porridge" price increase trend of the chemical market.

The four terms of in vitro diagnostic reagent calibrator, calibrator, calibrator, and calibration solution are essentially the same thing. The English term refers to one, namely "calibrator", and its purpose is to calibrate in vitro diagnostic reagents or systems. Most medical tests are biological measurements, which are basically relative measurements.

It was learned from the Xinjiang Oilfield Experimental Testing Institute (referred to as the laboratory) that the sterilization test carried out by the institute at the No. 802 water injection station of the No. 2 Oil Production Plant has achieved good results. 100% up to the standard, and the long-term bactericidal performance of the fungicide is obvious.

Market research firm IHSMarkit pointed out in the latest report "Supply Chain Disruption: Why It Will Continue to Happen in 2022" that in 2022, solving the problem of supply chain disruption will no longer be a "sprint" model, but will evolve into a well-run " Marathon" schedule mode.

Stability is the ability of an in vitro diagnostic reagent to maintain the consistency of characteristics over time, a basic attribute that a reagent must have, an important indicator to ensure the effectiveness of a reagent during use, and the responsibility of the manufacturer.

Disinfection with alcohol is common sense. What is strange is that the alcohol used in medical treatment is alcohol with a concentration of 75%, but pure alcohol cannot sterilize. What is the reason for this?

The main reasons for the deterioration and smell of metal cutting fluid are anaerobic bacteria and aerobic bacteria. Aerobic bacteria have a characteristic. They must have sufficient oxygen in the process of survival and reproduction.
