“How many bottles of medical disinfectant are needed on the front line, we have it here, send it immediately.” During the current round of the epidemic, Shandong Junxiu Biotechnology Co., Ltd. has a steady stream of vehicles transporting “anti-epidemic” materials to nucleic acid testing sites.

Workers are testing new medical disinfectants and biocides.

Disinfectants, masks, protective clothing, isolation gowns… This is a familiar item since the beginning of the pandemic. But how are disinfectants developed and produced, and how many behind-the-scenes heroes worked overtime to stick to the front line, and how many layers of inspection checkpoints must be passed through after masks, protective clothing and isolation gowns are produced? On August 19, the reporter walked into Shandong Junxiu Biotechnology Co., Ltd. to visit these unknown behind-the-scenes stories

Independent research and development of disinfectant spray

It was included in the special project of emergency research

In this round of the epidemic, medical disinfection and sterilization sprays can be seen everywhere in nucleic acid testing sites, and most of these antibacterial spray-type liquid dressings are independently developed and produced by Junxiu Biotechnology.

A small spray looks simple, but it condenses too much.

As an enterprise operating in the pharmaceutical industry for many years, Junxiu Biotech gives full play to its professional advantages in the field of biotechnology, when the epidemic hit last year, researchers successfully developed a new type of medical disinfection and sterilization spray in a very short time, “This product as a new medical disinfection and sterilization spray, can kill pathogens in a short time, achieve 10 seconds to kill bacteria, 30 seconds to kill mold, 5 minutes to kill viruses, with an effective rate of 99.99%. Jiang Hong, deputy general manager of Shandong Junxiu Biotechnology Co., Ltd., said.

The research and development of a product, behind the condensation of countless people’s efforts, the new medical disinfection and sterilization spray in the research and development process, to solve the previous disinfection and sterilization spray storage problems, “alcohol in the storage has extremely high requirements, and 84 disinfectant irritation, corrosiveness is also relatively large, we continue to adjust the formula, and finally developed a wide sterilization spectrum, with physical and chemical dual sterilization mechanism of the spray. Jiang Hong said, “This new medical disinfection and sterilization spray can effectively prevent the infection of drug-resistant bacteria, is non-corrosive and non-toxic to human skin, and has no pollution to the environment and is conducive to environmental protection.” It can also form a barrier layer on the surface of our skin to block pathogenic microorganisms and play a protective role. ”

In the production workshop, the reporter saw through the glass that the staff wearing work clothes meticulously looked at the instrument area on the equipment, and the production line was busy producing new medical disinfection and sterilization sprays, and the scene was busy and orderly. According to reports, the daily output of this product can reach more than 5,000 bottles. At present, Junxiu Biology has donated more than 50,000 bottles of new medical disinfection and sterilization spray to various and all levels of organizations in the city, and has been included in the “New Crown Epidemic Prevention and Control Emergency Research Project” in the Yantai Science and Technology Innovation and Development Plan, contributing “Junxiu” strength to the city’s fight against the epidemic.

Provide third-party testing services

Tightening the “safety valve” for epidemic prevention materials

Under the influence of the epidemic, many enterprises in our city have switched to the production of epidemic prevention and control products, so the testing of medical protective materials has become an important and critical link.

As a high-tech biological enterprise, Junxiu Biotech has rich experience in the construction of medical device quality system and has the ability of third-party testing services for biomedical materials. For medical protective materials and protective articles, the detection technology research of physical properties, trace residues of chemical substances and microbial sterility indicators has been carried out, and a complete set of testing systems such as dust particles, sedimentation bacteria and static pressure difference in the production workshop has been established, so as to provide accurate and efficient quality system consulting services for enterprises in production.

Walking into the gas chromatography room, the reporter saw that the staff was using a gas chromatograph to detect ethylene oxide residues on mask samples, “ethylene oxide is a sterilization gas, harmful to the human body, the mask will be analyzed when it leaves the factory, but there will be a certain residue.” We tested the ethylene oxide residue of the sample, and the mask was qualified and safe within the value specified by the state. Jiang Hong introduced.

In the liquid chromatography room, the residue of other organic solvents is detected. “We can also test the sterility of first-line materials such as protective clothing and isolation gowns and other physical properties to ensure the marketability of these products.” Jiang Hong said

“As a biotechnology enterprise, Junxiu Biotech has a strong sense of social responsibility and mission, and the in vitro three-dimensional evaluation system of lung tissue that we are currently developing can also provide technical support such as drug screening and vaccine research and development for the fight against the new coronavirus in the future.” The relevant person in charge of Junxiu Biological Company said.
