Custom Quartz Glass Sheets for German Client’s UVC Germicidal Lamp Project-Eva

Custom Quartz Glass Sheets for German Client’s UVC Germicidal Lamp Project

Business Case News — A professional German manufacturer specializing in commercial UVC disinfection lamps recently completed stable bulk procurement of high-purity quartz glass sheets, marking a successful long-term cooperation based on precise technical communication and strict quality confirmation. This case fully verifies the reliable performance of professional quartz glass components in high-standard European UVC sterilization equipment.

The client contacted our team in early 2025, proposing targeted customization demands for UVC lamp accessories. In the initial communication, the German engineering team clearly stated that conventional high borosilicate glass sheets were eliminated due to extremely low UVC transmittance, which directly reduced lamp disinfection efficiency and failed to meet EU commercial sterilization equipment standards. They required high-purity quartz sheets with stable ultraviolet transmittance, excellent thermal stability and precise dimensional tolerance for their new-generation household and commercial UVC germicidal lamps.

During repeated technical confirmation sessions, both sides finalized core product parameters. The client confirmed strict indicators including 99.99% high-purity fused silica material, over 92% UVC transmittance at 254nm wavelength, zero bubbles and no scratches on the glass surface. Meanwhile, they emphasized high thermal shock resistance, as UVC lamps generate continuous high heat during long-hour operation, requiring quartz sheets to withstand frequent temperature changes without cracking or light attenuation.

Our team provided free sample testing and detailed material certification reports to assist the client’s laboratory verification. After one month of continuous aging tests and disinfection efficiency tests by the German team, the quartz glass sheets fully met their equipment operating standards, showing stable UVC transmittance, no deformation and no performance decay under long-term high-temperature working conditions. The client highly recognized the product’s consistent quality and precise dimensional accuracy that supported seamless lamp assembly.

Officially launched in bulk production and delivery, the customized quartz glass sheets were officially applied to the client’s new UVC germicidal lamp series. Compared with previous alternative materials, the quartz-equipped lamps achieved 20% higher sterilization efficiency, longer service life and more stable long-term operation, perfectly adapting to European indoor air disinfection and surface sterilization scenarios.

Based on this successful cooperation, the German client has signed a long-term framework procurement agreement. Industry practitioners noted that high-purity quartz glass has become a core essential material for high-standard UVC disinfection equipment. This European cooperation case further proves that professional quartz glass components with superior optical and thermal performance can effectively help overseas equipment manufacturers improve product competitiveness and meet strict regional industrial standards.
