Tailored high-purity quartz apparatus engineered to meet stringent industrial and laboratory standards across Auckland, Christchurch, and Wellington.
Addressing the growing demand for ultra-pure silica solutions in New Zealand's pioneering research infrastructure and niche clean-tech ecosystems.
New Zealand's abundant geothermal power generation and pilot carbon-capture technologies require high-temperature, acid-resistant quartz sight tubes and sensor protection sleeves capable of withstanding corrosive hydrogen sulfide atmospheres.
Institutes such as Callaghan Innovation, GNS Science, and university labs across Auckland and Canterbury rely on custom quartz digestion tubes and CVD reactor tubes for cutting-edge materials science, nanotechnology, and geochemical analyses.
From sustainable dairy testing to high-throughput UV sterilization and precision optical water diagnostics, fused quartz tubes provide unparalleled UV-C transmittance and hygiene stability across New Zealand's primary export sectors.
With New Zealand's booming aerospace and photonics initiatives, ultra-low thermal expansion quartz ingots, windows, and irregular sheets offer the critical dimensional stability needed in extreme orbital testing and laser instrumentation.
Lianyungang Southeast Quartz Products Co., Ltd., established in 2015, is located in Donghai County, Lianyungang City, Jiangsu Province—a national base for silicon material industry. As a professional manufacturer integrating R&D, design, production, sales and import & export trade, the company relies on the superior high-quality quartz ore resources in Donghai County, deeply engages in the deep processing of quartz glass, and has become a core supplier of quartz consumables for photovoltaic, semiconductor, laboratory, chemical, lighting and other industries with mature production technology, strict quality control system and complete customized services.
The company has standardized production workshops, advanced quartz processing equipment and a professional R&D team, with full-process production capacity from quartz raw material processing to finished product manufacturing. It can produce a full range of quartz products, including high-purity fused quartz tubes, quartz furnace tubes, quartz bell jars, quartz boats, quartz lamp holders, quartz crucibles, quartz instruments (beakers, condensers, distillers, etc.), and tri-acid purification equipment. All products are made of high-purity fused quartz raw materials, featuring excellent high-temperature resistance (up to 1200℃), thermal shock resistance, corrosion resistance, high light transmittance and good electrical insulation performance, which can meet the demanding working conditions such as vacuum environment, high-temperature sintering, atmosphere control and precision experiments.
Bridging natural geographical advantages with precision thermal engineering to solve modern processing challenges.
Fused quartz exhibits an extremely low coefficient of thermal expansion (approx. 5.5 × 10-7 /°C), enabling custom quartz tubes to withstand violent thermal shocks—such as rapid cycling from 1100°C to room-temperature water quench without structural failure. This property makes them indispensable for New Zealand's advanced metallurgy and vacuum furnace applications.
Furthermore, as Kiwi researchers advance photovoltaic efficiency and next-generation perovskite thin-film architectures, the superior electrical insulation and ultra-low hydroxyl (OH) content of plasma-fused quartz tubes prevent ion migration and ensure pristine process cleanliness.
Every custom tube supplied to the New Zealand market undergoes rigorous CNC flanging, precision fire-polishing, ultrasonic washing, and dimension verification down to ±0.05mm tolerances, ensuring seamless integration into imported and custom-built reactor housings.
Adhering to the philosophy of "Quality First, Customer Supreme, Innovation-Driven, Integrity Management", the company has established a complete quality inspection system. All products undergo multiple tests such as helium mass spectrometry leak detection, pressure resistance test and purity test before leaving the factory to ensure stable performance, no impurities and no leakage. Meanwhile, the company provides flexible customized services, and can customize product sizes, structures and specifications according to customers' equipment parameters and process requirements, quickly responding to personalized orders.
With reliable product quality, efficient delivery capacity and thoughtful after-sales service, the products of Lianyungang Southeast Quartz Products Co., Ltd. not only cover all provinces and cities in China, but also are exported to many countries and regions in Europe, America, Southeast Asia, the Middle East, and the Oceania region including New Zealand, winning wide recognition and trust from customers worldwide.
Equipped with computerized hot-working lathes, continuous fusion furnaces, and cleanroom annealing chambers.
From Donghai crystal ore purification to automated flame blowing, annealing, cutting, and rigorous helium leak checking.
A professional manufacturer with over 10 years of experience in the quartz industry serving international partners in New Zealand and beyond.
Comprehensive custom specifications available with worldwide door-to-port logistics for New Zealand enterprises.
