Engineered to withstand rigorous thermal shock up to 1400°C, deep ultraviolet wavelengths (185 nm), and hostile chemical reagent conditions across Helsinki-Uusimaa laboratories and manufacturing plants.
From the Otaniemi innovation campus in Espoo to the VTT Technical Research Centre of Finland, discover how our custom quartz fabrication directly accelerates Finnish scientific and industrial infrastructure.
The Greater Helsinki region—anchored by the specialized research institutions of Aalto University, Micronova cleanrooms, and pioneering quantum hardware companies—represents one of Europe’s most demanding environments for raw materials engineering. High-purity quartz glass (synthetically fused silica and natural electric/flame-fused quartz) serves not merely as a passive housing material, but as an essential optical, thermal, and dielectric foundation for the entire Nordic deep-tech corridor.
Helsinki is the global epicenter for cryogenic dilution refrigeration systems. Our optical-grade JGS1 and low-bubble fused quartz windows provide thermal isolation barriers for optical readout lines down to millikelvin regimes. The minimal dielectric loss tangent (tan δ < 0.0001 at microwave frequencies) prevents phase decoherence in superconducting quantum qubits.
Within Finland's national semiconductor hub in Espoo, our custom quartz wafer boats, vertical furnace tubes, and CVD liner cylinders ensure zero metallic contamination (Fe < 0.1 ppm, Cu < 0.05 ppm). Annealed under strict polarization stress-testing, our components resist warping across repeated thermal cycles from 400°C to 1150°C during oxidation and LPCVD steps.
Finnish laser manufacturers rely on our triple-bore laser flow tubes, C-shape water jackets, and JGS1 laser cavity windows. Offering exceptional laser-induced damage thresholds (LIDT > 15 J/cm² at 1064 nm, 10 ns) and solarization resistance under continuous pulsed UV irradiation, our components ensure stable operation across industrial laser cutting and medical diagnostic instruments.
Understanding the interplay between European carbon neutrality targets, national quantum dominance, and ultra-pure synthetic materials.
Finland’s ambitious roadmap to scale superconducting quantum computers up to 150+ qubits demands ultra-clean, thermally matched viewport substrates. Standard borosilicate glasses fail catastrophically at cryogenic transitions due to differential contraction and helium permeability. Fused quartz features an exceptionally low coefficient of thermal expansion (α = 5.5 × 10⁻⁷ /°C between 20°C and 320°C), making it the indispensable material for non-magnetic cryostat optical windows and feedthrough sleeves.
As the Nordic industrial base pioneers fossil-free steelmaking and green hydrogen generation, high-temperature quartz apparatus is increasingly adopted in pilot reactors across the Helsinki and Pirkanmaa regions. Synthetic fused silica process tubes withstand continuous operational thresholds of 1100°C and peak excursion spikes to 1300°C without mechanical sagging or crystal devitrification into cristobalite, while maintaining absolute chemical inertness in the presence of acidic reducing gases.
Helsinki's active participation in the European Chips Act has fueled local development of integrated photonics for optical telecommunications. Our double-side polished ultra-thin fused silica sheets (0.1 mm to 0.5 mm) with parallelism <30 arc seconds serve as vital optical spacers, beam splitters, and submount carriers for laser diodes, ensuring minimal beam distortion and near-zero optical absorption from 200 nm deep ultraviolet up to 2500 nm near-infrared bands.

Combining the natural silica resources of Lianyungang with rigorous European quality assurance workflows.
Located in Lianyungang, China's premier silica hub, our SGS onsite-assessed industrial complex eliminates commercial middlemen, providing full cost predictability directly to Finnish enterprises.
From lump crushing, acid leaching, and horizontal furnace tube drawing to vacuum sealing, fire polishing, and ultrasonic cleaning, we manage the entire chain under unified traceable batch logs.
We execute diamond tool CNC milling, inner/outer threading (GL-threads), micro-drilling of multi-well plates, chamfering, and optical flat grinding to tolerances within ±0.005 mm based on customer STEP/DWG drawings.
100% of finished orders undergo stress birefringence inspection under cross-polarization optics. Products arrive in Helsinki accompanied by material certificates of analysis and full RoHS/REACH compliance files.
Addressing engineering specifications, customs documentation, packaging safety, and logistics to Helsinki-Vantaa and Vuosaari Harbour.
We employ a multi-tier protective packaging system tailored for delicate quartz glass. Each component is sealed in dust-free PE bags, enveloped in custom-molded high-density polyethylene (EPE) foam, encased in heavy-gauge dual-wall corrugated inner cartons, and suspended within reinforced wooden crates with internal shock-absorbing dampening. Crates destined for Finland comply with ISPM-15 phytosanitary heat-treatment regulations, backed by carrier insurance covering door-to-door transit.
For prototype components (1 to 5 pieces) based on customer CAD/STEP files, tooling and CNC fabrication typically require 5 to 9 business days. Express air shipping via DHL Express or FedEx Priority to Helsinki-Vantaa Airport (HEL) takes approximately 3 to 5 business days, enabling delivery to your testing bench within two calendar weeks from drawing sign-off. Bulk furnace tube runs ship via ocean freight to the Port of Helsinki (Vuosaari) within 28 to 35 days.
We supply complete documentation compliant with Finnish Customs (Tulli) and EU import regulations, including clean Commercial Invoices with correct TARIC/HS codes (7002.31 for quartz tubes, 7002.20 for rods, 7006.00 for plates), detailed Packing Lists, Certificates of Origin (COO), and comprehensive Material Inspection Certificates verifying SiO₂ purity, internal stress rating, and EU RoHS/REACH compliance.
While high-quality borosilicate 3.3 glass has a linear coefficient of thermal expansion of 3.3 × 10⁻⁶ /°C and safely endures temperature differentials of approximately 100°C to 150°C, high-purity fused quartz exhibits an expansion coefficient of only 5.5 × 10⁻⁷ /°C—roughly 6 times lower. A red-hot fused quartz tube heated to 1100°C can be submerged immediately into 20°C cold water without cracking or mechanical failure, making it essential for rapid thermal processing (RTP).
Specify JGS1 whenever your system operates within deep ultraviolet wavelengths below 250 nm (e.g., 193 nm ArF laser optics, UV excimer lamps, or UV-C disinfection analysis) or requires exceptional bubble-free optical homogeneity. JGS1 is synthesized through chemical vapor deposition of high-purity silicon tetrachloride (SiCl₄), yielding zero bubble inclusions and high UV transparency. For standard viewports, sight glasses, or furnace tubes running in visible-to-infrared light, flame-fused JGS2 offers matching thermal performance at reduced procurement cost.
Yes. Our CNC diamond grinding and lathe machinery routinely forms standard GL-14, GL-18, GL-25, GL-32, and GL-45 threads directly into fused quartz tubes. We also fabricate NW/KF vacuum flanges, ConFlat (CF) compatible mating surfaces, ground conical joints (e.g., standard taper 14/23, 24/29, 29/32), and custom side-arm manifolds with helium leak detection verifying seal integrity down to 10⁻⁹ mbar·l/s.
