High Precision Micro Quartz Glass Capillaries

High-precision micro quartz glass capillaries are ultra-thin, small-diameter tubes made from fused silica (synthetic quartz). They are used in applications requiring extreme thermal stability, chemical resistance, and precise dimensional control.

Key Features
✔ Ultra-Small Diameters (from a few microns up to 1-2 mm)
✔ High Thermal Resistance (up to 1200°C, low thermal expansion)
✔ Chemically Inert (resistant to acids, alkalis, and solvents)
✔ Optically Transparent (UV to IR transmission)
✔ Precision Geometry (tight tolerances for inner/outer diameters)

Applications of Micro Quartz Capillaries
1. Medical & Life Sciences
Microfluidics & Lab-on-a-Chip: Used in precise fluid handling, droplet generation, and biosensors.
Capillary Electrophoresis (CE): Separates DNA, proteins, and ions with high resolution.
Drug Delivery & Microneedles: Enables ultra-fine, controlled drug release.
2. Semiconductor & Electronics
Fiber Optic Manufacturing: Used in drawing optical fibers and photonic devices.
Micro-Electro-Mechanical Systems (MEMS): Precision fluidic channels and sensors.
Plasma Etching & Deposition: Delivers gases in semiconductor fabrication.
3. Analytical Chemistry & Spectroscopy
Gas Chromatography (GC) Columns: High-purity quartz capillaries improve separation efficiency.
Mass Spectrometry (MS) Inlets: Delivers samples to ionization sources with minimal contamination.
Laser-Induced Breakdown Spectroscopy (LIBS): Used in high-energy laser sampling.
4. Industrial & High-Temperature Processes
Thermocouple Protection: Shields temperature sensors in harsh environments.
Glass Fiber Production: Acts as a preform in fiber optic drawing.
High-Purity Chemical Transfer: Resists corrosion in aggressive chemical processes.
5. Optics & Photonics
Laser Beam Delivery: Guides laser light in medical and industrial systems.
Optical Fiber Preforms: Used in manufacturing specialty fibers (e.g., photonic crystal fibers).

Customization Options
✔ Inner/Outer Diameter Control (µm to mm range)
✔ Tapered or Conical Shapes

Why Choose Quartz Over Other Materials?

Property	Quartz Capillaries	Glass/Plastic Capillaries
Temperature Resistance	Up to 1200°C	<500°C (glass), <200°C (plastic)
Chemical Resistance	Excellent (HF-resistant grades available)	Poor (plastics degrade)
Optical Clarity	UV to IR transparent	Limited transmission
Dimensional Stability	Extremely precise	Prone to deformation

High-precision quartz capillaries are critical in fields requiring microscale fluid control, high-temperature stability, and chemical inertness. Their applications span medical diagnostics, semiconductor manufacturing, analytical chemistry, and advanced optics.
