Why is quartz used in Cuvette?
Why is quartz used in Cuvette?
Quartz cells provide more durability than plastic or glass. Quartz excels at transmitting UV light, and can be used for wavelengths ranging from 190 to 2500 nm.
How are quartz cuvettes made?
All our in-stock UV fused quartz cuvettes are made by diffusion bonding method. Quartz is heated to a high temperature and then adhered together by applying pressure.
What is the difference between quartz and glass cuvettes?
Glass and Quartz Cuvettes Glass cuvettes are used for measurements in the visible range from 320 to 2500 nm. Quartz cuvettes deliver precise results in the whole UV and visible range from 200 to 2500 nm. The smaller the manufacturing tolerance, the better and more repeatable the measurement.
Are quartz cuvettes reusable?
Clean cuvettes are the foundation of any photometric measurements. Even plastic cuvettes are disposable and no need to worry about cleaning, the rest of the quartz or glass cuvettes are reusable and require cleaning to avoid cross-contamination.
Why quartz does not absorb UV light?
Ultraviolet light has shorter wavelength than visible light, although ultraviolet waves are invisible to human eyes. If we use glass in place of quartz then glass will absorb ultraviolet rays while quartz does not. Ultraviolet radiant has a low power of penetration, hence it directly affects the human body as well.
Why do we use quartz?
For centuries, quartz has been used in jewelry production and as gemstones. The hard, polishable, crystalline and durable nature of quartz make it an excellent material for this purpose.
Which material is better for cuvette glass or quartz?
Thermal Properties – A quartz material has a much higher melting point than glass. Chemical Compatibility – The chemical structure of quartz is stronger than glass making it able to handle a bigger range of chemicals that would melt or damage a glass cuvette.
How do you clean a quartz cell?
Soak cells in 50% sulfuric acid 2M and 50% DI water. Cells can safely be soaked for 20 minutes. Remove cells from bath and thoroughly rinse with water. Let air dry.
Can UVC pass through quartz?
Why quartz and not an ordinary glass sleeves? Ordinary glass is not transparent to germicidal ultraviolet radiation wavelengths—quartz is. In order to provide disinfection, CRYSTAL CLEAR™ Quartz Sleeves allow precisely the right amount of radiation to pass through into the air or water.
Does quartz glass block UV?
Pure quartz does not filter UV, so there is a risk of UV exposure from halogen bulbs. Sometimes the lights are made using special high-temperature glass (which at least filters UVB) or doped quartz (to block UV).
Why do quartz crystals vibrate?
Quartz crystals are a piezoelectric material. So, what people do to make them vibrate is apply a voltage, which distorts the crystal (kind of like applying a force to compress a spring), and then when the voltage is removed, the crystal springs back into place, which creates an electric field.
