Why Choose proQuarz for Your Laboratory?
- Extreme Thermal Stability: proQuarz products are designed to operate at continuous temperatures of 1100 °C, with brief peaks even higher, making them ideal for ash testing and thermal decomposition.
- Superior Chemical Purity: Manufactured from high-purity fused silica, these products minimize the risk of sample contamination from trace metals, which is critical for ultra-pure analytical chemistry.
- Unmatched Chemical Resistance: Quartz glass is highly resistant to water, saline solutions, and most acids, offering a longer service life in aggressive chemical environments compared to standard labware.
- Exceptional Optical Properties: Their clear quartz glass offers excellent light transmission across the UV, visible, and infrared spectrums, making it the material of choice for optical research.
- Precision German Craftsmanship: Combining master glass-blowing with automated precision, proQuarz delivers complex glass geometries with tight tolerances for specialized experimental setups.
Frequently Asked Questions
1. What is the main advantage of quartz glass over borosilicate glass?
While borosilicate glass is excellent for general use, quartz glass offers much higher thermal resistance (up to 1100 °C) and superior UV transparency, as well as significantly higher purity for trace analysis.
2. Can proQuarz crucibles be used in muffle furnaces?
Yes, proQuarz crucibles are specifically designed for high-temperature applications in muffle furnaces, providing excellent resistance to thermal shock and chemical attack during ashing processes.
3. Is quartz glass resistant to hydrofluoric acid?
No. Like almost all glass types, quartz glass is susceptible to hydrofluoric acid and phosphoric acid at high temperatures. It should not be used with these specific chemicals if the integrity of the vessel is critical.
4. How should I clean my proQuarz glassware to maintain its purity?
For general cleaning, standard laboratory detergents are fine. For high-purity applications, quartz glass can be cleaned with high-purity acids (except HF) to remove trace contaminants before rinsing with deionized water.
