Laboratory &amp; Scientific Research<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Laboratory glassware:<\/strong>&nbsp;High-temperature test tubes, combustion tubes, and reaction vessels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Analytical instruments:<\/strong>&nbsp;Used in spectrometers, UV analyzers, and other optical instruments requiring UV transmittance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Chemical processing:<\/strong>&nbsp;Used as tubes for handling corrosive chemicals or high-purity reactions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4. Environmental &amp; Medical<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Water sterilizers:<\/strong>&nbsp;Quartz sleeves that protect UV lamps in water treatment systems (drinking water, wastewater, pool disinfection).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Air purifiers:<\/strong>&nbsp;UV lamp tubes used to kill bacteria and viruses in air ducts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Medical devices:<\/strong>&nbsp;Used in phototherapy equipment and medical analytical instruments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5. Solar &amp; Energy<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Solar simulators:<\/strong>&nbsp;Quartz tubes used in artificial light source systems for solar panel testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Light guides:<\/strong>&nbsp;High-temperature light transmission for specialized energy applications.<\/p>\n\n\n\n<figure
