Medical treatment and skin disease treatmentSeveral questions about UVC LED disinfection and UVC wavelengthCan UVC help prevent**** transmission by reducing contamination?based on existing evidence, we believe so. Here's why:UVC light has been used extensively for more than 40 years in disinfecting drinking water, waste water, air, pharmaceutical products, and surfaces against awhole suite of human pathogens (Fluence UV Dose Required review IUVA). All bacteria and *** tested to date (many hundreds over the years, including other ****) respond to UV disinfection. Some organisms are more susceptible to UVC disinfection than others, but all tested so far do respond at the appropriate doses.What is the "sterilizing range" of UV?According to the International Ultraviolet Association, "the ultraviolet spectrum (the 'sterilization' region) that is important for water and air disinfection is the range absorbed by DNA (RNA in some ***). This sterilization range is about 200-300nm."It is known that the bactericidal range extends above 280 nm, and it is now generally considered to extend to 300 nm, however this may also change with more research. Scientists have shown that ultraviolet light with awavelength between 280nm and 300nm can be used for disinfection and sterilization.What is the optimal wavelength for disinfection?There is amisunderstanding that 254nm is the optimal wavelength for disinfection because the peak wavelength of alow-pressure mercury lamp (determined solely by the physics of the lamp) is 253.7nm. The wavelength of 265 nm is generally considered to be optimal because this wavelength is the peak of the DNA absorption curve. However, arange of wavelengths have disinfection and sterilization effects.Ultraviolet mercury lamps were once considered the best choice for disinfection and sterilization. Why is this?Historically, mercury lamps have been the only option for disinfection and sterilization. With the advancement of UV LED technology, there are new options because LEDs are smaller, more powerful, non-toxic, longer life, more energy efficient, and allow more switching times. This makes the solution smaller, battery-powered, more portable, and capable of instant full-light output.What is the difference in wavelength characteristics between UVC LEDs and mercury lamps?Low-pressure mercury lamps emit nearly monochromatic light with awavelength of 253.7 nm. Low-pressure mercury lamps (fluorescent tubes) and high-pressure mercury lamps are also used for disinfection and sterilization. These lamps have abroader spectral distribution, including wavelengths used for sterilization. UVC LEDs can be focused on anarrow range of specific wavelengths, which allows the solution to be tailored to specific application needs.Does the peak absorption wavelength of DNA vary by bacteria?Yes. Different types of peak absorption wavelengths are indeed different, but most of them are around 265nm.Can asingle wavelength eliminate all bacteria?Yes, asingle wavelength can be used. However, bacteria have different optimal absorption wavelengths.How is the bactericidal effect determined?Generally, power intensity, wavelength, and duration of irradiation are used to determine the bactericidal effect. For example, in water, there may be multiple bacteria with different optimal absorption wavelengths. For any given wavelength of germicidal UV, the power and time of irradiation need to be calculated to achieve the desired level of disinfection.Are UVC disinfection devices safe?Like any disinfection system, UVC devices must be used properly to be safe.) They all produce varying amounts of UVC light in wavelengths of 200nm-280nm. This UVC light is much "stronger" than normal sunlight, and can cause asevere sunburn-like reaction to your skin, and similarly, could damage the retina of your eye, if exposed. Some devices also produce ozone as part of their cycle, others produce light and heat like an arc welder, others move during their cycles. Hence, general machine-human safety needs to be considered with all disinfection devices, and these considerations should be addressed in the operations manual, in the user training, and appropriate safety compliance.Are there performance standards and UVC validation protocols for UV disinfection devices?Given the wide array of UVC devices marketed for disinfection of air, water and solid surfaces, the lack of uniform performance standards and the highly variable degree of research, development and validation testing that is performed on different devices, the IUVA urges consumers to exercise caution when selecting equipment and look for evidence of third party testing as well as certification of device materials and electrical components by well-known organizations such as UL, CSA, DVGW-OVGW or other international requirements as applicable.For UVC devices designed to inactivate air and solid surfaces in the healthcare industry, members of IUVA are working diligently with other national standards organizations in the lighting and healthcare industry to develop disinfection testing standards[x]. The goal is to develop guidance that will help healthcare providers world-wide choose the best possible technologies for their institutions to use in the fight against multiple drug resistant organisms and other pathogensApplication:Packaging & ShppingShiment:DHL,EMS,FedEX,UPS,TNT ,Marine and Air transport Available.PaymentT/T, Western Union, Paypal.etc.Package1000pcs / ReelOur ServicesOur Service1.We offer 3 Years Warranty For All of Our Products. 2.
