Quartz Glass Cuvette with Lid Custom Fabrication

Quartz Glass Cuvette with Lid

Quartz cuvette (or quartz cell) can be matched a lid as sealed cover. Quartz cuvette can also be made in large sizes. The edges of quartz cuvettes are generally relatively flat and smooth. Because its welding process is different from other quartz containers, such as quartz tanks. The most important aspect of making a quartz cuvette is that the quartz plate used must meet the optical requirements. Because its purpose is not only for containers, but also for achieving a certain pass rate of ultraviolet radiation.

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.
