In the realm of analytical chemistry and industrial quality control, the Quartz Evaporating Dish stands as an indispensable tool. Specifically designed for sample digestion and testing, these vessels are crafted from high-purity fused silica, offering unparalleled chemical inertness and thermal stability. Unlike standard laboratory glassware, quartz provides a contamination-free environment essential for trace element analysis.
Beyond simple evaporation, our quartz dishes are utilized in complex digestion protocols involving concentrated nitric, sulfuric, or perchloric acids. In environmental testing, they are used to break down soil and water samples to detect heavy metals. In the semiconductor industry, quartz evaporating dishes are used to test the purity of process chemicals, where even parts-per-billion (ppb) contamination is unacceptable.
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.
The global demand for high-purity quartzware is surging, driven by the rapid expansion of the Photovoltaic (PV) and Semiconductor sectors. As sample digestion techniques evolve toward automation and microwave-assisted systems, the physical requirements for quartz evaporating dishes have become more stringent.
Furthermore, the shift towards "Green Chemistry" has increased the usage of quartz due to its longevity and recyclability compared to disposable plastic alternatives. Our production line at Leef Quartz is adapting to these trends by implementing precision CNC machining to ensure that every dish meets exact volumetric and structural specifications for automated testing environments.
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 and large-scale bulk orders with efficient delivery.
When performing Sample Digestion and Testing, the thermal shock resistance of the quartz dish is paramount. Our products can withstand a sudden temperature change from 1000°C to room temperature without cracking. This is vital for "wet digestion" methods where samples are heated intensely and then rapidly cooled for dilution.
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.
