Square Optical Quartz Glass Cuvette Custom Fabrication

Square Optical Quartz Glass Cuvette

Square optical quartz cuvette is composed of 5 optically polished quartz plates. Each quartz plate has a polishing level of at least 60/40 smoothness or higher. The splicing between quartz plates adopts high-temperature quartz powder melting technology. High temperature powder melting technology has excellent characteristics compared to ordinary heat welding. For example, high transmittance, higher precision, and greater durability. Our company can custom fabrication square quartz cuvettes of various sizes. Welcome to inquire.

The main characteristics of quartz glass

1. Heat resistance

The softening point of quartz glass is 1730 ℃. It can be used for a long time below 1100 ℃, and the temperature for short time use is up to 1450 ℃.

2. Light transmission

Quartz glass has good light transmittance in the entire optical spectrum from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.

3. Electrical insulation

The electrical resistance of quartz glass is equivalent to 10,000 times that of ordinary glass.

4. Chemical stability

Quartz glass almost don’t react chemically with other acid-base substances except hydrofluoric acid.

5. Thermal stability

Quartz glass has low expansion coefficient, and it can withstand drastic temperature changes.

6. Hardness characteristics

With the hardness of Mohs level 7, the mechanical properties of quartz glass are better than hard glass and ceramics, and the strength of quartz glass improves with the increase of temperature, reaching its maximum when approaching the annealing temperature.
