Under the Swiss-Liechtenstein Customs Treaty of 1923, Liechtenstein forms a unified customs area with Switzerland. Shipments addressed to companies in Vaduz, Schaan, Balzers, or other municipalities are routed through Swiss customs clearance protocols (EZV / BAZG). Lovri Quartz provides fully compliant export paperwork, including commercial invoices with correct Harmonized System (HS) codes (typically HS 7002 for quartz tubes/rods and HS 7017 for laboratory/industrial quartz apparatus), packing lists, and certificates of origin. Delivery is executed seamlessly via international air express (DHL/FedEx/UPS) or air freight forwarding via Zurich Airport (ZRH), arriving directly at your facility without regional secondary clearing delays.
Yes. Our CNC machining centers and optical processing facilities operate directly from customer engineering drawings and digital files. We accept standard European CAD formats including STEP (.stp), IGES (.igs), DWG, and vector DXF, as well as dimensioned PDF engineering drawings. We routinely machine custom ground threads, multi-bore hole patterns, conical tapers, wafer slot profiles, vacuum O-ring sealing grooves, and complex laser cooling geometries with mechanical tolerances held to ±0.005 mm depending on part complexity.
The fundamental distinction lies in raw material synthesis and trace hydroxyl (OH⁻) content:
JGS1 is synthetic fused silica synthesized from silicon tetrachloride vapor. It features zero bubble inclusions, superior optical homogeneity, and high transmission in the deep ultraviolet range (DUV > 90% at 193–266 nm), making it critical for UV laser optics and lithography.
JGS2 is flame-fused from premium natural quartz crystals. It offers excellent transmission across 220 nm to 2500 nm, serving as an economical, robust standard for sight glasses, UV lamps, and general viewports.
JGS3 is electrically vacuum-fused quartz with exceptionally low OH⁻ content (< 5 ppm). This eliminates the prominent water absorption bands at 1.4 µm, 2.2 µm, and 2.73 µm, allowing high transmittance up to 3500 nm in the mid-infrared spectrum.
Thermal failure in fused quartz is almost exclusively triggered by internal residual stresses introduced during flame working, tube drawing, or welding. At Lovri, every welded boat, flange assembly, and heavy-walled furnace tube undergoes automated thermal de-stressing cycles in computer-controlled electric annealing furnaces up to 1215°C, followed by programmed slow cooling. Every completed piece is visually verified using a high-sensitivity polariscope stress tester to guarantee residual optical path difference is kept below international safety thresholds.
We actively support R&D departments, academic institutions, and prototyping phases across Liechtenstein. For custom CNC quartz parts, optical plates, and specialized welded apparatus, our minimum order quantity starts at just 1 to 5 pieces. Standard raw tubing and plate prototypes can typically be fabricated and dispatched within 7 to 10 working days following final drawing confirmation. Volume production schedules are customized according to your enterprise supply frame agreements.
Yes. As a verified supplier to major European technology sectors, we supply comprehensive quality documentation upon request. This includes formal Material Test Certificates (MTC) stating SiO₂ percentage and trace element ICP-OES analysis, certificates of conformity with EU Directive 2011/65/EU (RoHS) and Regulation (EC) No 1907/2006 (REACH), as well as optical transmission spectrometer curves (UV-Vis-NIR) for precision window orders.
We adhere to strict multi-layered shock-isolation packaging standards. Each quartz component is thoroughly ultrasonic-cleaned, dried, wrapped in non-scratch protective film or dust-free vacuum bags, and nested in multi-density, die-cut expanded polyethylene (EPE) foam. Heavy quartz tubes and complex lab apparatus are enclosed in impact-resistant, fumigated wooden shipping crates reinforced with internal shock indicators (Drop-N-Tell / Tip-N-Tell) for total transit transparency.
We accept wire transfer (T/T) settlements in major international currencies, including Swiss Francs (CHF), Euros (EUR), and US Dollars (USD). For established industrial clients and long-term procurement partnerships within the EEA and Switzerland, flexible commercial credit milestones and blanket order schedules are available subject to standard trade credit assessment.
