The wise choice of cell culture - the advantages of pure copper inhibition

Send your sister a new routine: green rose confession

The history of bronze is not simple

Copper, the first metal used by humans, has a history of more than 5,000 years. It is extracted from malachite, and then made by a skilled craftsman into a variety of wine, food, water, dowry, ornamental and daily life appliances.

The casting and use of bronzes embodies the labor and wisdom of human ancestors. After the sacred sangtian, the bronzes handed down are symbols of world civilization and are regarded as treasures by all mankind.

Since bronzes are buried in the soil for thousands of years, the rust will be emitted in layers, but the rust color of the bronzes in different regions is not the same, which is related to different groundwater quality and other organic matter corroding the surface and producing different chemical reactions. For example, bronze wares unearthed in Anhui Province, the rust layer is grayish green; while the bronze wares unearthed in Hunan, there are emerald green rust layers, sparkling crystals, known as "puddle" devices; bronzes unearthed in the Central Plains, rich in rust, rust Changeable, or black ash, or jujube red, or gray-green, or silver.

- The rust is colorful, and the copper and green are the most classic, which is another beauty that time gives bronze.

Ancient for today, high efficiency and antibacterial

With the development of technology, people have discovered more of the beauty of copper and applied it to life.

For example, copper faucets, the main material is copper and zinc, commonly known as brass, the main reason for the use of brass is copper bacteriostasis. According to historical records, Egypt, 2,500 BC, began using copper for wound disinfection, treatment of eye infections and burns, and disinfection of drinking water.

The scientific evidence from many world authorities such as the US EPA (Environmental Protection Agency) that bacteriostatic copper kills more than 99.9% of bacteria in two hours, making it the most effective contact surface material in the world. Surface materials with antibacterial properties can effectively control the growth of various drug-resistant bacteria in hospitals, such as fearful intestinal bacteria, staphylococcus and Escherichia coli. No other material (such as silver ion coating or stainless steel) can match it.

Copper can quickly kill super bacteria such as MRSA, and bacteria can not produce antibodies. The inner wall of copper faucets will not breed bacteria, which is not the advantage of other materials (such as stainless steel, plastic).

Based on this highly effective bacteriostatic performance, copper is currently the only one certified by the US Environmental Protection Agency.

- The reason why copper can effectively inhibit the growth of bacteria has the following three characteristics:

✦ First: Copper can continuously kill all kinds of microorganisms attached to their surface, and its effect is far superior to stainless steel and various silver-containing coatings;

✦Second: Durable, never exhausted, providing continuous and uninterrupted protection throughout the hospital's life cycle, and providing effective bacteriostatic effects when re-contaminated;

✦ Third: It is absolutely safe for humans and the surrounding environment, and can be recycled. It is the most green medical material known at present.

Pure copper liner, a smart choice for cell culture

In our daily cell culture work, it is a wise choice to choose a tank with a pure copper liner to provide continuous and credible pollution protection for our precious cells. Thermo Scientific CO2 cell incubator adopts the concept of pure copper antibacterial in the industry. With advanced technology and reliable product quality, it has been favored by users.

With the passage of time, the surface of 100% pure copper is oxidized, the rust layer is gradually rich, the rust color is changeable, or black ash, or jujube skin red, or grayish green, or silver white, the antibacterial efficiency is increased, and the antimicrobial ability is greatly improved. .

The antibacterial test was carried out by coating 1 cm 2 of pure copper covered with oxide and a copper alloy which was not discolored. Escherichia coli bacteria were spotted on copper sheets under air drying conditions to determine the amount of microbial survival.

- Tests have shown that samples with high coverage of copper and oxides exhibit excellent antibacterial properties over time. The non-discoloring alloy with low copper content has a poor antibacterial effect.

While the antibacterial ability is improving, the rust is also deducing another beauty. It truly and perfectly interprets the natural beauty of the chemical reaction and the vicissitudes of time.
