proQuarz

proQuarz is a premier German manufacturer specializing in high-purity quartz glass and technical glass solutions, headquartered in Mainz. Since its founding, the company has spent decades fulfilling its mission to provide "Precision in Quartz," becoming a global specialist for industries requiring extreme thermal and chemical resistance. proQuarz is internationally renowned for its expertise in processing fused silica and opaque quartz glass for the semiconductor, solar, and chemical industries. By maintaining a focus on traditional glass-blowing craftsmanship combined with modern CNC precision grinding, the brand ensures that its glassware can withstand temperatures up to 1100 °C while maintaining high optical purity. Today, proQuarz is a vital partner for high-temperature research, delivering "Made in Germany" excellence that ensures durability and reliability in the most demanding laboratory environments.

The proQuarz range at LabFriend features professional general laboratory consumables, headlined by their high-purity quartz glass beakers, flasks, and crucibles. These items are essential for trace element analysis and high-temperature furnace applications where standard borosilicate glass would fail. For specialized chemical processing, the brand provides advanced vessel support through their range of quartz combustion tubes and custom-engineered reaction vessels designed for maximum chemical inertness. Their portfolio also encompasses essential optical components, featuring quartz glass plates and windows that offer superior UV transmission for spectroscopic applications. To support the semiconductor and solar sectors, proQuarz offers specialized carriers and boat systems engineered for high mechanical stability under extreme heat. By choosing proQuarz through LabFriend, you benefit from competitive pricing and fast shipping on premium quartz technology designed for professional high-performance applications.

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.
