High-Purity Quartz Capillaries: Precision-Crafted Core Components for Diverse High-End Applications​

Property Category

Key Specifications & Advantages

Chemical Inertness

Resists most acids, alkalis, and organic solvents (excluding hydrofluoric acid and hot phosphoric acid); smooth, non-adsorptive surface ensures high analysis sensitivity/accuracy.

Thermal Stability

Softening point >1600°C (supports long-term high-temperature work); thermal expansion coefficient = 0.5×10⁻⁶/°C (excellent thermal shock resistance, no deformation risk).

Optical Transparency

High transmittance in 190-2500nm (UV-NIR) band; ideal for optical window applications (e.g., fluorescence detection, laser transmission).

Mechanical Performance

Mohs hardness 7; available inner diameter: 0.05mm-9mm, outer diameter: 0.08mm-10mm; precise dimensional control balances mechanical strength and microscale adaptability (note: avoid severe impact due to brittleness).

Field

Specific Applications

Analytical Chemistry

Core component for Capillary Electrophoresis (CE); enables efficient separation of DNA, proteins, and small molecules for high-sensitivity detection.

Biomedicine

Integrates into microfluidic chips (single-cell analysis, drug screening); supports high-sensitivity biosensors (via fluorescence/Raman technology) for accurate biomarker detection.

Optical Fiber & Optoelectronics

Compatible with PLC splitters, borosilicate single bore ferrule,quartz glass ferrule,fiber connectors, WDM devices, and fiber optic sensors; serves as array unit for Hollow-Core Photonic Crystal Fibers (HC-PCF) to transmit high-power lasers or special-band optical signals.

Industry & Research

High-temperature corrosion-resistant reaction channels (semiconductor material synthesis); low-background sample tubes for X-ray Diffraction (XRD); applicable in laser wire bonding and electronic component assembly.
