What is disinfectant Chlorine-containing disinfectants with sodium hypochlorite as the main component can be widely used to kill bacteria and viruses, prevent diseases, and inhibit spreading. If the concentration of sodium hypochlorite is too high, the toxicity of the disinfectant will be too high and it will affect the safety of the environment. If the concentration is too low, disinfection may not kill the germs and virus. Therefore, the effectiveness of chlorine of the disinfectant needs to be controlled. How to determine the effectiveness of chlorine in the disinfectant? Effectiveness of chlorine refers to the chlorine content in sodium hypochlorite with strong oxidizing properties. Determination method of effectiveness of chlorine in disinfectant In an acidic environment, KI (potassium iodide) and sodium hypochlorite can undergo a redox reaction, generating I2( iodine element) and Cl-(chloride ions). Using starch solution as an indicator, the effective chlorine content can be measured by titration with sodium thiosulfate standard solution. The traditional volumetric method requires the use of an alkaline burette and relies on the change in the color of the starch indicator to determine the end point, which has high requirements for the operator. After practical exploration and research, the application engineer of REX u

Thanks Letter from Wuhan Recently, Shanghai INESA Scientific Instrument Co., Ltd. received a thanks letter from Wuhan Ecology and Environment Bureau and a commemorative cup engraved with "Love from Wuhan protection War " from the Ministry of Ecology and Environment. COVID-19 epidemic outbreak at this year which catch attention from everyone. After Wuhan was fully lockdown, the Wuhan Environmental Monitoring Center urgently needed a disinfectant tester. Experts from the Ministry of Production and Environment immediately contacted the us. INESA resumed workshop to urgent production which was donated to Wuhan. INESA Scientific Instrument CO. LTD will continue to devote itself, adhering to the original intention of developing national scientific instruments, fulfilling the mission of state-owned enterprises, repaying the society with practical actions, and making a beautiful China.

Water quality analyzers donated to Wuhan To help the overloaded hosptial dealing with wastewater quality monitoring in wuhan, Shanghai INESA Scientific Instrument Co., Ltd. donated a batch water quality analyzer again after the first donation of water quality monitoring instruments which meet the needs of the Emergency Center of the Wuhan Ministry of Ecology and Environment. These water quality analyzers are used for Chloride test, on-site monitoring, detection of disinfection and discharge of water in the hospital. As one of the birthplaces of Chinese analytical instruments, REX stand with Wuhan and the Wolrd.To find more information of INESA Scientific Instrument, please visit www.inesarex.com.
