Quartz Volumetric Flask

The Quartz Volumetric Flask is a precision-crafted laboratory vessel engineered for accurate preparation and measurement of standard solutions, particularly in high-purity chemical, pharmaceutical, and analytical laboratories. Fabricated from high-purity fused quartz (≥99.99% SiO₂), this flask combines dimensional accuracy, exceptional durability, and chemical inertness, making it indispensable for trace-level analysis and high-temperature procedures. Its narrow neck and calibrated volume line ensure consistent and repeatable measurements, while the flat bottom and long neck design supports ease of filling, mixing, and visibility of the meniscus. The flask can withstand extreme thermal conditions, including open flame, autoclaving, and high-temperature dry heat sterilization, with minimal thermal expansion and excellent resistance to thermal shock. Suitable for use in cleanroom environments, UV-sensitive applications, and acidic or oxidizing media, the quartz volumetric flask provides unmatched performance where borosilicate glass is insufficient.
