Explore our primary selection of fused quartz components designed for seamless integration with block digestion systems, ICP-OES/ICP-MS sample preparation, and high-temperature industrial setups in Sri Lanka.
As Sri Lanka advances its industrial sectors, heavy emphasis has been placed on rigorous analytical testing, soil sample digestion, mineral assaying, and chemical quality control. The transition toward stringent international export compliance—particularly in agricultural products like Ceylon Tea, spices, and coconut derivatives—demands flawless laboratory sample preparation techniques.
Quartz digestion tubes are vital components in wet acid digestion protocols (utilizing concentrated Nitric Acid, Aqua Regia, and Perchloric Acid) prior to Atomic Absorption Spectroscopy (AAS), ICP-OES, and ICP-MS analysis. Standard borosilicate glass degrades rapidly and leaches background elements under high-temperature acid digestion. High-purity fused silica quartz digestion tubes supply Sri Lankan researchers and commercial testing facilities with zero background contamination and exceptional resistance to thermal shock.
Analytical accuracy starts with sample digestion. Impurities present in low-grade laboratory vessel materials ruin trace detection limits. Our quartz digestion tubes feature continuous operating temperatures up to 1200°C, an ultra-low thermal expansion coefficient ($5.5 \times 10^{-7}/^\circ\text{C}$), and a SiO2 purity level exceeding 99.99%.
From university research centers in Kandy to industrial testing laboratories in Colombo, our quartz digestion tubes and customized glass apparatus support essential operations.
Sri Lanka is renowned worldwide for Ceylon Tea. Stringent residue limits enforced by the EU, Japan, and North America necessitate rigorous heavy metal testing. Our quartz digestion tubes withstand continuous boiling of concentrated $HNO_3/HClO_4$ mixtures without releasing silicon or metal ions into the digestate.
Sri Lanka possesses the world's purest natural vein graphite (99%+ carbon content) and rich mineral sand reserves. Acid digestion of dense mineral ores requires sustained high temperatures in block digestors, where quartz tubes provide superior structural integrity over conventional glassware.
Water quality management in inland lakes, coastal zones, and wastewater discharge channels requires Kjeldahl nitrogen digestion and trace element analysis. Our custom quartz digestion vessels match all standard heating blocks utilized by Sri Lankan environmental scientists.
Donghai County Leef Quartz Technology Co., Ltd. was founded in 2022 as a subsidiary of Lianyungang Southeast Quartz Products Co., Ltd., which was established in 2015. We are located in Donghai County, Lianyungang City, Jiangsu Province — known as "China Crystal Capital" and a national-level silicon material industry base.
Blessed with superior high-purity quartz ore resources, Donghai is a core production area of quartz raw materials in China. Relying on local high-grade quartz veins, we focus on the deep processing of quartz glass, and are a professional manufacturer integrating design, production, sales and foreign trade.
With mature production technology, strict quality control and complete customized services, we have become a trusted supplier of quartz consumables for industries including photovoltaics, semiconductors, laboratories, chemical engineering and lighting across international markets, including full service to laboratories and manufacturing facilities in Sri Lanka.
"Leveraging the mineral wealth of China's Crystal Capital to deliver ultra-pure fused silica solutions directly to Sri Lankan laboratories and industrial enterprises."
We operate standardized production workshops equipped with a full set of advanced equipment for quartz cutting, grinding and high-temperature forming, establishing a complete production line from quartz processing to finished product inspection.
Backed by a professional production management team with over 10 years of industry experience, we specialize in process optimization and customized manufacturing. We support rapid prototyping and mass production for various complex products, with an annual capacity of hundreds of thousands of pieces.
We accept both small-batch custom orders for specialized Sri Lankan research facilities and large-scale bulk orders for industrial manufacturers with efficient delivery. By continuously upgrading production techniques, we improve product precision and stability, providing cost-effective quartz solutions for global customers.
All products are made of high-purity fused quartz raw materials, featuring excellent heat resistance (up to 1200°C), thermal shock resistance, corrosion resistance, high light transmittance and electrical insulation. They are widely used in photovoltaic manufacturing, semiconductor production, chemical laboratory analysis, chemical anti-corrosion treatment, lighting equipment and other general industrial and experimental applications in Sri Lanka. We also provide custom processing for special-shaped products according to customer drawings to meet personalized requirements.
Ordering high-grade laboratory consumables internationally requires assurance of safe packaging, reliable freight schedules, and technical precision. We provide end-to-end logistics solutions tailored to Sri Lanka's key ports and air cargo hubs.
