Advantages of Quartz Glass for Laboratory Instrument Fabrication

1. Ultra-High Chemical Inertness and Corrosion Resistance

Quartz glass is chemically inert with stable molecular structure, showing superior corrosion resistance superior to most glass and metal materials in laboratory chemical environments:

· Resistant to almost all inorganic acids (hydrochloric acid, sulfuric acid, nitric acid, aqua regia) and organic solvents (alcohols, esters, alkanes, etc.) at room and high temperatures.

· Stable in neutral and weakly alkaline environments; only corroded by hydrofluoric acid and hot concentrated phosphoric acid, which are easy to avoid in conventional experimental design.

· No ion precipitation or material dissolution occurs during long-term contact with chemical reagents, eliminating interference with experimental indicators such as ion concentration and elemental analysis.

It is widely used in corrosive reaction vessels, trace element analysis containers, chromatographic components, distillation and extraction devices to ensure the authenticity and repeatability of experimental data.

2. Broad-Spectrum Optical Transparency

Quartz glass has unique optical transmission properties that ordinary borosilicate glass cannot match, supporting optical and spectral laboratory applications:

· High transmittance in the ultraviolet (UV), visible and near-infrared bands, especially transparent to short-wave ultraviolet light.

· Low light absorption and scattering, reducing signal loss in optical detection and spectral analysis.

· No obvious discoloration or light transmittance attenuation after long-term light or high-temperature exposure.

Suitable for manufacturing spectrophotometer cells, UV reaction cuvettes, optical flow cells, laser transmission components, spectral sampling accessories and optical detection probes.

3. Ultra-High Purity & Low Contamination Risk

High-purity quartz glass has a SiO2​ purity of ≥99.9%, and ultra-high-purity grades can reach ≥99.999%, with extremely low content of metal impurities (Na, K, Fe, Cu, Pb, etc.):

· Impurity precipitation is negligible, which is essential for trace analysis, micro-detection and high-purity material synthesis experiments.

· Avoids introducing exogenous metal ions or organic impurities that interfere with elemental analysis, environmental monitoring, semiconductor cleaning and pharmaceutical testing.

· Meets the strict cleanliness requirements of semiconductor laboratories, analytical chemistry laboratories and new energy material research laboratories.

Common matching instruments: micro-reaction vessels, impurity-free digestion tubes, semiconductor cleaning fixtures, standard sampling containers.

4. Excellent Electrical Insulation Properties

Quartz glass is an outstanding high-grade electrical insulating material with stable electrical properties in wide temperature and frequency ranges:

· Ultra-high volume resistivity and surface resistivity, effectively isolating current and preventing electrical leakage.

· Low dielectric constant and extremely low dielectric loss, suitable for high-frequency and high-voltage electrical experimental environments.

· Insulation performance does not degrade significantly under high temperature or high humidity, ensuring the safety and accuracy of electrical and electrochemical instruments.

Applied in electrochemical detection sleeves, high-voltage experimental insulation components, electrode protection tubes and electronic material testing devices.

Conclusion

Quartz glass is an optimal high-performance material for manufacturing high-end and precision laboratory instruments. Its comprehensive advantages in thermal stability, chemical corrosion resistance, optical transparency, material purity and electrical insulation make it irreplaceable in experiments requiring high temperature, strong corrosion, trace analysis, optical detection and high cleanliness. For laboratories pursuing data accuracy, experimental safety and instrument durability, quartz glass instruments provide reliable hardware support and significantly improve the reliability and repeatability of experimental results.
