Custom Quartz Glass Photocatalytic Reactor for Lab

Quartz glass photocatalytic reactor is an experimental or industrial equipment specifically designed for photocatalytic reactions. Its mainly feature is that its reaction chamber or main optical components are made of quartz glass material. It provides an ideal environment for achieving efficient photocatalytic processes and is widely used in research fields such as environmental governance, energy conversion, and chemical synthesis.
Quartz glass is an ideal material for manufacturing photocatalytic reactors, mainly due to the following reasons:
Extremely high UV transmittance:
This is the core advantage of quartz. Ordinary glass strongly absorbs ultraviolet light with wavelengths less than 300 nm, while quartz glass has extremely high transmittance in the deep ultraviolet (~185 nm) to near-infrared bands (usually up to 90% or more).
Most efficient photocatalysts, such as TiO ₂, require UV excitation (with an absorption edge typically around 385 nm). Quartz ensures that the energy of the ultraviolet light source is fully utilized, greatly improving the photocatalytic efficiency.
Excellent thermal stability:
Quartz has an extremely low coefficient of thermal expansion and can withstand drastic temperature changes (from high temperature to rapid cooling) without easily breaking.
In photocatalytic reactions, a light source (such as a mercury lamp) generates a large amount of heat, and the reaction itself may also be exothermic. Quartz reactors can operate stably in higher temperature environments.
High purity and chemical inertness:
High purity quartz hardly introduces metal impurities, avoiding contamination of the reaction system or unknown effects on catalytic reactions.
It has excellent corrosion resistance and can withstand the erosion of strong acids, strong bases (except hydrofluoric acid), and organic solvents, with a wide range of applications.
Mechanical strength and durability:
Compared to ordinary glass, quartz glass has higher mechanical strength and longer service life.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
