While there have been tremendous advancements in the laboratories, today’s scientists continue to seek ways to improve productivity and reliability of data. Users of Lab Water Purification Systems are constantly looking for compact, ergonomic systems and software so that they can advance science, further faster. New lab water systems need to address these pain points, allowing scientists to focus on problem solving, without worrying about the purity of their water.

While there have been tremendous advancements in the laboratories, today’s scientists continue to seek ways to improve productivity and reliability of data. Users of Lab Water Purification Systems are constantly looking for compact, ergonomic systems and software so that they can advance science, further faster. New lab water systems need to address these pain points, allowing scientists to focus on problem solving, without worrying about the purity of their water.

To ensure that new lab water purification systems meet customers’ evolving needs, companies are constantly trying to build innovations that are smaller and easier-to-use. But these Lab Water purification systems require UV lamps to monitor TOC (Total Organic Carbons). These UV lamps contain Mercury, a highly hazardous chemical that cannot be disposed under normal conditions, which is a potential harm to the environment. As Purposeful innovation is all about developing technology that not only improves our life, but also is environment friendly.

Recently to overcome this potential harm, companies have introduced Lab Water Purification system delivering ultrapure water with UV lamps inside which does not contain mercury and delivers better results. The lamps used in these New Lab Water Purification Systems are based on the Excimer technology, which enables extraction of UV radiation without much self-absorption. These rare gases based excimer lamps are completely non-hazardous and also, more environmentally friendly compared to the mercury ones.

The mercury lamps are also high heating, that can sometimes cause explosion, leading into mixing of the mercury with water. Besides this, there are several other problems with the current mercury based UV-lamp technology, that include high start-up time, sleeve breakage, filament failure, and dimensional restrictions. Also, the mercury based lamps are non- repairable.

On the other hand, the Excimer Lamps do not contain any harmful acid, neither do they result in toxic organic solvents. The lamps with Excimer technology consume less energy and also operate at a low temperature. Unlike the mercury based lamps, these lamps start instantly, usually within 1 millisecond.

Using the Excimer technology, companies have built Smaller devices with ergonomic design that reduces waste and increases productivity/accelerates research. Using this technology in water purifiers not only increase their productivity, but also cut costs by low energy consumption and higher efficiency rate. This new Mercury-free lamp technology is indeed a purposeful innovation that not only delivers better result, but is also environmentally friendly.
