Fused Quartz (Quartz Glass) - Qsil PH from Qsil Netherlands

Ved Group is the Exclusive Authorized Agent/Distributor/Partner/Representative in India for Qsil Fused Quartz Netherlands.

UV Quartz Sleeves are available in ready stock for all UV lamps. UV Quartz Sleeves available In most Diameters and Lengths. Customised UV Quartz Sleeves available.

UV Quartz Sleeves help from a safety perspective as UV lamps contain mercury. Quartz Sleeve is a product used over the UV lamp to protect the UV lamp from breaking. Good quality Quartz (such as Qsil Netherlands) is the only substance which allows 92% of the UV-C to get transmitted. Any other substance is a UV-block (borosilicate glass, normal glass, plastic, teflon etc).
