Featured Precision Quartz Components & Capillaries
Integrated manufacturing spanning raw Donghai crystal refinement to sub-micron surface polishing.
Precision Innovation in Vaud
Specialized Applications in the Lausanne Biotech & Photonics Hub
How our ultra-pure quartz capillary tubing aligns directly with research institutes and advanced industries around Lake Geneva.
Capillary Electrophoresis & CE-MS
In the laboratories of the EPFL Innovation Park and biopharmaceutical analytical spin-offs across the Canton of Vaud, capillary electrophoresis (CE) coupled with Mass Spectrometry demands pristine fused silica capillaries. With inner diameters down to 10 μm and uniform polyimide outer coatings, our tubes offer exceptional inner surface smoothness (Ra < 0.05 μm), mitigating sample adsorption in protein mapping and chiral separations.
Gas Chromatography (GC) & HPLC Flow Cells
Swiss food quality centers, environmental monitors, and forensic testing facilities around Lausanne rely on capillary columns with homogeneous dimensional tolerances. Our thermal-shock-resistant fused silica sustains continuous isothermal operating cycles up to 400 °C without degradation, ensuring high column efficiency, zero gas leaks, and ultra-low background noise during high-throughput compound verification.
Microfluidic Chips & Lab-on-a-Chip
Switzerland's healthtech corridor thrives on miniaturized analytical platforms. Our custom slotted quartz plates and micro-capillaries serve as the backbone for droplet generators, flow cytometry cells, and optical detection windows. The wide UV-to-NIR transmission spectrum (> 90% at 200–2500 nm) allows deep-UV fluorescence microscopy and laser-induced fluorescence (LIF) without intrinsic optical distortion.

Emerging Trends Shaping Swiss Capillary Sourcing
Strategic supply-chain evolution in Lausanne, Geneva, and the Health Valley.
Demand for Synthetic Grade Purity
Traditional natural quartz often presents trace element variances. Swiss scientific laboratories are increasingly specifying synthetic fused silica capillaries derived from vapor-phase silicon tetrachloride hydrolysis. This guarantees baseline hydroxyl (OH) control, virtually zero metallic impurities (< 1 ppm), and uncompromised transmission for deep-UV excimer laser waveguides and advanced cytometry.
Dual-Source Supply Chain Resilience
While Swiss engineers maintain rigorous QA standards, local and European glass blowers face prolonged lead times and surging labor expenditures. Leading instrumentation manufacturers in Vaud are transitioning to certified direct Chinese manufacturing partners who can supply drawing-matched capillaries with comprehensive ISO9001 and RoHS documentation, reducing unit costs by 35% to 50% without compromising micron tolerances.
Sub-Micron Miniaturization in Micro-Optics
With the convergence of Lausanne’s microengineering and photonics startups, there is surging interest in micro-bore circular, square, and multi-lumen capillary profiles. Tight geometric coaxiality, concentricity tolerances below 1%, and custom laser-cleaved or fire-polished end geometries are essential to eliminate chromatographic dead volume and optimize optical fiber splicing sleeves.

Integrated Production Power
Direct Manufacturing from China's Quartz Capital
Donghai Raw Material Access Combined with State-of-the-Art Cleanroom Thermal Drawing.
Raw Material Purity ≤ 20 ppm
Situated in Donghai County—the epicenter of natural quartz refinement in China—our 50-mu production facility leverages 13 grades of in-house refined quartz sand. Backed by RMB 10 million in fixed manufacturing assets, we control the entire lifecycle from powder purification to thermal drawing, eliminating the structural micro-bubbles and devitrification defects that undermine capillary tensile strength.
Provincial Science & Tech Recognition
Our R&D achievements include the high-purity 320 mm core quartz tube executed as an official Jiangsu Provincial Science & Technology Support Project, along with a 520 mm large-diameter oxidation tube passed through National New Product preliminary review. We invest over RMB 5 million annually in drawing towers, laser interferometers, and diamond grinding stations.
Swiss-Grade Logistics & Rapid Service
Handling fragility across intercontinental corridors is our core competence. All capillary tubes and optical sheets feature custom inner pearl-cotton cushioning, vacuum-sealed barrier packaging, and ISPM-15 compliant fumigation-free wooden crates. With direct express and air shipping lines to Geneva Airport (GVA) and Zurich (ZRH), plus an average inquiry response time under 2 hours, global procurement is fully frictionless.

Frequently Asked Questions for Swiss Importers
Clear answers on technical specifications, customs compliance, and supply chain logistics.
How do you verify the dimensional concentricity and inner diameter of quartz capillaries?
Every production batch undergoes online optical micrometric monitoring during thermal drawing, followed by high-resolution cross-sectional microscope inspection. We measure internal diameter (ID), outer diameter (OD), and wall runout at both ends. Inspection certificates displaying statistical tolerances (typically within ± 0.002 mm to ± 0.005 mm depending on custom design) are included with each batch.
Can you provide custom protective coatings, such as polyimide or UV-transparent fluoropolymers?
Yes. Bare fused silica capillaries are extremely brittle once exposed to ambient atmospheric moisture. We offer automated continuous dip/thermal-cure polyimide coating (typical thickness 12–24 μm) providing flexible tensile strength over 100 kpsi, along with specialized optical detection burn-through windows laser-ablated to precise aperture lengths for on-column spectrophotometric detection.
What are the customs and Swiss import compliance standards (e.g., Swissdec, VAT, RoHS)?
Our fused quartz products fall under HS Code 7002.31 (Tubes of fused quartz or other fused silica) and 7006.00 (Glass plates, sheets, and discs). Switzerland imposes zero customs duties on industrial manufactured glass under standard bilateral tariff schedules, with only standard Swiss Import VAT (8.1%) applicable. We provide full commercial invoices, packing lists with net/gross weights, EUR.1 / Certificates of Origin, and complete RoHS/REACH compliance documentation.
How do you manage prototype orders for EPFL laboratories or research spin-offs?
We actively support low-volume, high-specification prototyping for research centers and university institutes. Prototype trial batches (e.g., 5 to 50 pieces of custom-cut or flared capillary tubes, slotted plates, or micro-wells) can be produced directly from customer-supplied CAD or STEP drawings, with engineering turnaround times of 7 to 10 working days.
What is the distinction between natural fused quartz and synthetic fused silica in deep-UV applications?
Natural fused quartz is melted from natural rock crystal/sand; it retains trace aluminum, titanium, and alkali ions (≤ 20 ppm) which create absorption bands in the deep ultraviolet spectrum (180–240 nm). Synthetic silica, synthesized from high-purity chemical gas feeds, exhibits virtually zero metallic impurities, making it the essential material for deep-UV (193 nm / 254 nm) spectroscopy, excimer laser delivery, and semiconductor photomask plates.
How are fragile capillary bundles packaged to guarantee zero breakage to Lausanne?
Precision capillaries are first aligned in rigid acrylic or polycarbonate protective sleeves, sealed with moisture-barrier film to prevent static surface flaws, and cushioned in high-density polyethylene (EPE) foam cavities. These are then placed within drop-tested corrugated cartons and finally packed in reinforced plywood outer cases. Our historical transit breakage rate across European routes is less than 0.2%.
