Quartz beakers are high-performance laboratory vessels made from high-purity fused silica glass, designed for precise heating, mixing, and chemical processing in demanding laboratory and industrial environments. These beakers provide exceptional thermal shock resistance and are chemically inert to virtually all acids (except hydrofluoric acid) and most compounds.
Applications
Quartz beakers serve critical roles across multiple industries:
-
Semiconductor Manufacturing: Wafer wet cleaning processes and high-purity chemical handling.
-
Materials Science: High-temperature experiments requiring contamination-free environments.
-
Chemical Research: Handling of corrosive acids, alkalis, and reactive substances.
-
Environmental Analysis: Trace metal determination in environmental samples where chemical purity is essential.
-
Metallurgy and Precious Metal Analysis: High-temperature analytical procedures.
-
Optical and Photovoltaic Industries: UV and visible light transmission applications.
Material and Construction
Quartz beakers are manufactured from high-purity fused silica glass (SiO₂ content > 99.99%). The material offers:
-
Low Thermal Expansion Coefficient: ~5.5×10⁻⁷ /°C, ensuring superior thermal shock resistance.
-
Continuous Operating Temperature: Up to 1200°C; short-term use up to 1400°C.
-
Exceptional Chemical Resistance: Inert to most acids and alkalis (excluding hydrofluoric acid and hot phosphoric acid).
-
High Optical Clarity: Excellent UV, visible, and infrared light transmission.
-
Mohs Hardness: 5.3–6.5, offering good scratch resistance.
Quartz beakers are available in low form (wide base, shorter height) and tall form (narrower base, taller profile) configurations, each with a convenient pouring spout.
⚠ Important Note: Quartz beakers are considered consumable labware and are not covered by standard warranties.
