Industry-leading transparent quartz tube solutions — designed to meet the precision demands of New Zealand's research institutes, industrial manufacturers, and clean energy developers.
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.
New Zealand's rapidly evolving industrial and research landscape has created growing demand for high-performance transparent quartz tubes across a wide range of sectors.
With New Zealand's commitment to 100% renewable electricity by 2030, the photovoltaic sector is booming. Transparent quartz tubes are essential for solar cell diffusion furnaces, enabling high-purity silicon wafer processing at temperatures exceeding 1100°C for maximum energy conversion efficiency.
Leading institutions such as the University of Auckland, Victoria University of Wellington, and GNS Science regularly utilize transparent quartz tubes for high-temperature chemical synthesis, spectroscopy, and materials science research requiring exceptional optical clarity and chemical inertness.
New Zealand's food processing, water treatment, and manufacturing sectors increasingly rely on UV disinfection and high-intensity industrial lighting systems. Quartz tubes with high UV transmittance are the preferred housing material for germicidal lamps and infrared heating elements in these applications.
New Zealand's chemical industry, particularly around the Taranaki energy sector and Marsden Point, demands corrosion-resistant, high-purity quartz components for reactors and analytical instruments. Fused quartz tubes withstand aggressive acids and alkalis far better than conventional borosilicate glass.
New Zealand's pharmaceutical manufacturers and medical device producers require ultra-pure quartz tubes for sterilisation equipment, UV phototherapy devices, and analytical instruments. The non-contaminating nature of fused quartz ensures compliance with stringent Medsafe regulatory standards.
New Zealand's world-class water quality standards drive significant investment in UV water purification systems. High-transmittance transparent quartz sleeves surrounding UV lamps are critical components in municipal water treatment plants and agricultural irrigation disinfection systems across the country.
Several powerful macro and industry-specific trends are accelerating the adoption of transparent quartz tube technology across New Zealand's commercial and industrial sectors.
New Zealand's ambitious renewable energy targets — including a government mandate for 100% renewable electricity generation — are driving rapid expansion in solar panel manufacturing support, wind turbine component production, and energy storage systems, all of which require quartz tube components in their production processes. The New Zealand Energy Strategy 2024–2050 further reinforces this trajectory.
New Zealand is positioning itself as a technology innovation hub in the Asia-Pacific region. The growth of local tech startups, the expansion of NZTech sector, and partnerships with global semiconductor companies are creating consistent demand for precision quartz tubes used in diffusion, oxidation, and LPCVD processes for wafer fabrication.
New Zealand's rigorous MPI (Ministry for Primary Industries) food safety standards are driving widespread adoption of UV sterilisation technologies in dairy, meat processing, and horticultural export facilities. Transparent quartz tubes — the core component of UV lamp systems — are experiencing increased procurement across these regulated industries.
Significant government investment in New Zealand's research infrastructure through programmes such as the NZ Research & Technology Strategy and the Endeavour Fund is equipping universities and Crown Research Institutes with advanced laboratory facilities. This directly increases procurement of high-quality quartz labware, including transparent quartz tubes, furnace tubes, and optical components.
The China–New Zealand Free Trade Agreement (upgraded in 2022) has significantly reduced tariff barriers on industrial materials, making it more commercially viable for New Zealand businesses to source premium quartz products directly from leading Chinese manufacturers. This trade environment enables cost-competitive access to world-class quartz tube technology.
New Zealand's engineering and manufacturing companies are increasingly demanding bespoke quartz components rather than standard catalogue items. The trend toward custom OD/ID dimensions, specialised end configurations, and application-specific coatings is driving partnerships with flexible manufacturers capable of rapid custom production runs — a core strength of our factory.
Every quartz tube we manufacture undergoes rigorous multi-stage quality control, delivering performance characteristics that meet and exceed the requirements of New Zealand's most demanding industrial and scientific applications.
Withstands continuous operating temperatures up to 1200°C and peak temperatures of 1450°C, ideal for tube furnaces, sintering ovens, and CVD reactors.
SiO₂ content ≥99.99%, with trace metal impurities controlled at the ppb level. Verified by helium mass spectrometry leak detection and purity testing before shipment.
Near-zero UV/VIS absorption from 150nm to 3500nm wavelength range, making our transparent quartz tubes the preferred choice for optical, UV, and infrared applications.
Extremely low coefficient of thermal expansion (0.55×10⁻⁶/°C) ensures excellent resistance to sudden temperature changes — critical for laboratory and industrial cycling processes.
Resistant to virtually all acids (except hydrofluoric acid) and alkalis at elevated temperatures, ensuring long service life in corrosive process environments.
Any OD from 5mm to 600mm, wall thickness, length, end configurations (open, closed, flanged), and surface finishes available. Rapid turnaround for NZ customers.
All products undergo helium mass spectrometry leak detection, pressure resistance testing, dimensional inspection, and purity verification before export to New Zealand.
Experienced in shipping to New Zealand ports (Auckland, Tauranga, Christchurch). Professional packaging with shock-proof materials ensures zero breakage in transit.
A professional manufacturer with over 10 years of experience in the quartz industry — serving New Zealand's most advanced industrial and scientific sectors.
