The uv lamps for water treatment consist of specialized low pressure mercury vapor lamps that produce ultraviolet radiation at 254 nm or medium pressure uv lamps that produce a polychromatic output from 200 nm to visible and infrared energy. Uv c is found within 100 280 nm range. Replacement ultraviolet uv lamp comparable to the thermo scientific barnstead lmx13 uv lamp. The labstrong 185 254 nm uv lamp is suitable for.

Replacement ultraviolet uv lamp comparable to the thermo scientific barnstead lmx13 uv lamp. 4 6 out of 5 stars 7 ratings. The lamp is effective at germicidal and total organic carbon toc reduction in water through the use of 185 and 254 nanometer nm uv wavelengths. 1 5 kg lamp head only rating.

The labstrong 185 254 nm uv lamp is suitable for. Comparisons were made with results from a conventional 254 nm uv germicidal lamp used as positive control. Germicidal uv lamps of 254 nm prevent contamination in research laboratories. Uvc with a wavelength of 222 nm had a potent germicidal effect on vegetative bacterial cells yeast and viruses and was as efficient as 245 nm uvc.

The uv lamp never contacts the water. Unlike conventional 254 nm uvc 222 nm uvc is harmless to human skin and eyes. We found that 222 nm light kills mrsa efficiently but unlike conventional germicidal uv lamps 254 nm it produces almost no premutagenic uv associated dna lesions in a 3d human skin model and it is not cytotoxic to exposed mammalian skin. 5 0 out of 5 stars great replacement germicidal lamp.

Ultraviolet c uvc light has been used to inactivate several pathogens. It is either housed in a quartz glass sleeve inside the water. As a result our germicidal lamps are extremely effective in. Uv 400w mercury hg bulb.

The uv light emitted by a source is expressed in watts w and the irradiation density is expressed in watts per square meter w m2. In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side. 200 nm 400 nm. Reviewed in the united states on december 19 2013.

The lamp is effective at germicidal and total organic carbon toc reduction in water through the use of 185 and 254 nanometer nm uv wavelengths.
