Abstract of Quartz Capillaries
Transparent Quartz Capillaries Large Bore/Small Bore Irregular Glass Tubing
Quartz capillaries are tubular optical components manufactured through precision drawing processes using high-purity fused silica (SiO₂). Classified into large-bore (OD≥1mm) and small-bore (OD<1mm) variants, they are extensively utilized in analytical instruments, fiber optic communications, biomedical devices, and semiconductor applications. As a specialized optical component manufacturer, ZMSH focuses on the R&D and production of quartz capillaries, offering high-precision custom processing. ZMSH support client-provided drawings for customization, accommodating diverse dimensions, wall thicknesses, ID/OD ratios, and specialized coating requirements. Our capabilities span from laboratory-scale small batches to industrial mass production, guaranteeing exceptional performance in light transmission, chemical stability, and mechanical strength.

Key Features of Quartz Capillaries
The core characteristics of quartz capillaries include:
1. High-Purity Material: SiO₂ content ≥99.99%, ensuring minimal impurity interference for high-precision analysis.
2. Superior Thermal Stability: Thermal expansion coefficient of only 0.55×10⁻⁶/°C, withstanding temperatures up to 1100°C (short-term).
3. Chemical Inertness: Resistant to acid/alkali corrosion (except HF), compatible with aggressive solvent environments.
4. Dimensional Versatility: Large-bore capillaries (OD 1mm–20mm) for fluid transfer; small-bore (OD 0.1mm–1mm) for microfluidics or fiber coupling.
5. Optical Performance: High transmittance from UV to IR (170nm–2500nm), with optional AR coatings to enhance transmission.
Primary applications of Quartz Capillaries
Quartz capillaries play pivotal roles in:
1. Analytical Instruments: Separation columns for GC/LC systems, requiring high purity and pressure resistance.
2. Fiber Optics: Preforms for fiber drawing or coupling components, demanding micron-level dimensional precision.
3. Biomedical: Microchannels in lab-on-a-chip devices, necessitating biocompatibility and chemical stability.
4. Semiconductor Processes: Gas delivery tubes for CVD/etching, tolerant to high-temperature corrosive gases.
5. Research Systems: Beam guide tubes for synchrotron/laser experiments, requiring high vacuum compatibility.
ZMSH's Services
ZMSH delivers end-to-end customization for quartz capillaries, including material selection, precision drawing, dimensional machining, and functional treatments. Clients may submit CAD drawings or technical specifications; we employ CNC laser cutting and precision polishing to achieve complex structures (e.g., tapered ends, multi-lumen capillaries) with tolerances as tight as ±0.01mm. For specialized needs, we offer silanized inner walls (hydrophobicity enhancement), metallized coatings (conductive applications), or high-pressure reinforcement (burst pressure >50MPa). All products undergo diameter consistency inspection (ovality ≤1%) and transmittance testing, accompanied by ISO-certified test reports. We support R&D-scale orders (minimum 10 units) and large-scale OEM collaborations, with flexible lead times, complemented by technical consulting and after-sales support.

Q&A
1. Q: What are quartz capillary tubes used for?
A: Quartz capillary tubes are primarily used in high-precision
analytical instruments (HPLC/GC), fiber optics, and semiconductor
manufacturing due to their ultra-purity, thermal stability, and
chemical resistance – making them ideal for labs and high-tech
industries.
2. Q: Why choose quartz over glass capillaries?
A: Quartz capillaries outperform glass in high-temperature
applications (up to 1100°C), UV transparency, and chemical
durability, ensuring longer lifespan and better accuracy in
critical processes like chemical analysis and laser systems.
