View Product SpecificationsEngineering Precision Quartz Micro Tubing: Structural Integrity & Optical Purity
A rigorous examination of synthetic fused silica vs. natural fused quartz capillaries, chemical inertness, and thermal stability under extreme mechanical and environmental operating thresholds.
Ultra-High Purity & Trace Metal Control
Our quartz micro tubing is drawn from chemical-vapor synthetic silica (JGS1) and vacuum-melted natural quartz (JGS2/JGS3), guaranteeing an absolute SiO₂ purity exceeding 99.999%. With cumulative transition metals (Fe, Cu, Ni, Cr) held strictly under 0.1 ppm, fluorescence background noise is eliminated in single-molecule bio-assays and capillary electrophoresis.
Near-Zero Thermal Expansion & Shock Resistance
Featuring a thermal expansion coefficient of only 5.5 × 10⁻⁷ /°C from 20°C to 1000°C, our micro-capillaries endure instantaneous thermal gradients (ΔT > 1100°C) without micro-fissuring or structural failure. This thermodynamic stability is critical for downhole logging, high-temperature gas chromatography, and laser ablation nozzles.
Deep-UV to Far-Infrared Spectral Transmission
Fabricated with controlled hydroxyl (OH⁻) concentrations—from low-OH synthetic varieties (<1 ppm OH) for extended NIR transmission up to 3500 nm, to high-OH grades (>1200 ppm OH) that prevent solarization under intense 193 nm Excimer and 214 nm UV deuterium illumination in HPLC absorbance flow detectors.
| Material Classification | SiO₂ Purity (%) | Transmission Bandwidth | OH Content | Softening Point | Primary Industrial Vector |
|---|---|---|---|---|---|
| JGS1 Synthetic Silica | > 99.9999% | 185 nm – 2,500 nm | > 1200 ppm | 1730 °C | HPLC, UV Capillary Electrophoresis, Flow Cytometry |
| JGS2 Optical Fused Quartz | > 99.995% | 220 nm – 2,500 nm | 30 – 150 ppm | 1680 °C | Microfluidic Chips, Fiber Ferrules, Laser Cooling Sleeves |
| JGS3 Infrared Silica | > 99.998% | 260 nm – 3,500 nm | < 5 ppm | 1710 °C | FTIR Spectroscopy, Gas Analysis, Downhole Pyrometry |
| Borosilicate 3.3 Glass | ~ 81% | 350 nm – 2,200 nm | N/A | 820 °C | General Laboratory Fluidics, Low-Temp Capillaries |
Macro Industry Solutions & Precision Fluidic Architectures
From analytical instrumentation to extreme UV lithography tools, our microbore quartz tubes provide nanoscale dimensional fidelity where thermal drift or chemical leaching cannot be tolerated.
Chromatography & CE Flow Cells
Inner diameter (ID) geometries down to 5 μm with total inner surface roughness Ra < 0.02 μm minimize peak broadening, eliminate wall adsorption in protein separations, and support operational pressures up to 15,000 psi in UHPLC columns.
Semiconductor Sub-Torr Gas Delivery
Furnace injection nozzles, purge capillaries, and precursor delivery lances machined from trace-metal certified quartzware. Built to withstand dry reactive chlorine, fluorine plasma, and temperatures exceeding 1150°C during oxidation and LPCVD cycles.
Fiber Optic Splicing & Micro-Ferrules
Custom D-bore, dual-bore, and hexagonal capillary sleeves featuring concentricity tolerances under 1 μm (TIR). Used globally in DWDM collimators, fiber array blocks, and laser diode pigtail alignment for telecommunication backbones.
Bio-MEMS & Single-Cell Cytometry
Hydrodynamically focused square-bore quartz flow cells with optical window clarity on four orthogonal faces. Guarantees distortion-free laser excitation and scattered light collection for high-throughput cancer cell sorting and hematology systems.
China Factory 4.0: Supply Chain Resilience & Micron Precision
Operating a modernized 3,000+ m² manufacturing center in Tianjin, China. Our vertically integrated pipeline unifies raw ingot processing, high-speed automated redraw towers, cold CNC edging, and laser micro-cutting under one roof.
Automated Laser Redraw Towers
Equipped with closed-loop computerized tensioning and multi-axis dual laser scanning micrometers monitoring dimensional variation at 1,000 Hz. Any deviation in wall thickness or ovality triggers instant thermo-mechanical compensations in real time.
Integrated Hot & Cold Finishing
By housing oxyhydrogen flame polishing, high-speed diamond slicing, end-face optical lapping, and laser cleavage in the same production floor, we eliminate inter-vendor logistical latency and prevent edge chipping or micro-fissuring.
Direct-to-Foundry Economics
Direct supply-chain agreements with primary high-purity silica quartz mines eliminate distribution markups, empowering international instrument manufacturers to lower Bill-of-Materials (BOM) costs by 28% to 42% relative to domestic Western suppliers.
Technical Roadmap: Next-Generation Micro-Fluidic & Optical Frontiers
Anticipating the demands of quantum photonics, nanoscale fluidics, and extreme UV environments through active R&D investments and advanced materials science.
Sub-Micron ID Geometries
Refining stable commercial draws for single-digit micron bores (down to 2 μm ± 0.2 μm) for high-pressure nanofluidic chromatography and direct mass spectrometer electrospray tips.
Custom Multi-Bore Precision
Tooling and draw standardization for 4-bore, 7-bore, and honeycomb micro-capillaries designed for multi-analyte concurrent sensing and high-efficiency optical fiber bundles.
Polyimide & Fluoropolymer Jacketing
High-speed in-line secondary coating extrusion supporting polyimide, silicone, and PFA sheathing for flexural reinforcement, enabling dynamic bend radii down to 10 mm without fracturing.
Doped Silicas & Hollow Core PBGF

Full regulatory documentation provided with every wholesale shipment: complete Certificate of Conformance (CoC), ICP-MS trace elemental analysis, RoHS/REACH declaration, and precise batch interferometric inspection reports.
Reliable Worldwide Direct Logistics
With direct corporate courier accounts (DHL Express, FedEx Priority, and air freight forwarders), we deliver door-to-door to North America, Europe, Japan, and Southeast Asia within 3 to 5 business days, backed by specialized shock-proof packaging.
Frequently Asked Questions: Technical Sourcing & Tolerancing
Clear, direct engineering answers to the most critical dimensional, chemical, and commercial questions asked by procurement directors and optical design engineers.
On custom runs with outer diameters between 100 μm and 1.5 mm, our automated laser redraw towers routinely achieve OD tolerances of ±0.001 mm (±1 μm) and inner diameter (ID) tolerances down to ±0.001 mm. Concentricity (Total Indicated Runout) is maintained within 2% of total wall thickness.
JGS1 is synthetic fused silica with highest transmission down to 185 nm and negligible bubble inclusions, making it the industry standard for UV spectrophotometry and capillary electrophoresis. JGS2 offers cost-effective excellence across visible wavelengths (220–2500 nm). JGS3 is ultra-low OH (<5 ppm), eliminating the deep 2.73 μm absorption band for infrared sensors.
Yes. We utilize precision diamond-wheel dicing with ultrasonic dampening and ultra-fast picosecond laser cleaving. This guarantees end-face perpendicularity within <0.5° and eliminates micro-chips on the inner bore edge, ensuring frictionless fluid entry and zero optical beam scattering.
Fused silica is chemically inert to virtually all acids (including aggressive aqua regia, nitric, sulfuric, and hydrochloric acids) and organic solvents. The only substances that actively attack quartz are hydrofluoric acid (HF), concentrated hot phosphoric acid (>150°C), and strong hot alkaline solutions (pH > 11 at elevated temperatures).
We redraw preforms into square, rectangular, D-shape, elliptical, and multi-lumen micro-tubes (e.g., dual-bore, 4-bore, or 7-bore arrays). Square and rectangular profiles are extensively chosen for on-column optical detection because their flat external faces eliminate cylindrical lens distortion.
Our engineering desk provides formal Design for Manufacturability (DFM) reviews and quotes within 24 business hours. Rapid custom capillary prototypes typically ship within 7 to 10 working days, while recurring wholesale production runs (10,000+ meters) ship within 3 to 4 weeks.
