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.

Water treatment agent refers to chemicals added in the process of water treatment in order to remove most of the harmful substances in water (such as corrosive substances, metal ions, dirt and microorganisms, etc.) and obtain qualified civil or industrial water. Global water treatment industry.

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.

Generally speaking, a certain preservative can only kill or suppress a certain colony. Therefore, two or more preservatives are usually used in cosmetic formulations to achieve a broad antibacterial spectrum.

Liquid detergent contains a lot of water and organic matter, which provides a good source of nutrients for the growth of microorganisms. If microbial contamination sources are accidentally introduced during processing, storage, and use, the rapid growth and reproduction of bacteria and fungi will not only cause product deterioration, but may also endanger the health of consumers. The use of preservatives can effectively prevent this phenomenon. In the choice of preservatives, any preservative has the characteristics of the best use conditions and use restrictions.

What is sterilization (sterilazation, sterilant)? Refers to the process of using strong physical and chemical factors to kill or remove all pathogenic and non-pathogenic microorganisms in the external environment, including bacterial spores and fungal spores. It is an absolute concept. The effect is expressed by the sterilization rate, generally ≥99.9999%.

Paint preservatives are characterized by high efficiency in killing bacteria, fungi, yeasts, and low dosage; good compatibility with paints, emulsions and other materials; easy to dilute with water, and easy to add paint, coatings and emulsions or In other similar materials; when pH≤9, it is stable.

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