Product Description

The 50ml borosilicate flask, a small-neck lab flask, is triangular chemistry glassware designed for precision in laboratory workflows. Crafted from high-purity borosilicate glass, it offers thermal stability (-30°C to 300°C) and chemical resistance, compatible with 19/22 or 24/29 ground glass joints for seamless integration with condensers, heating mantles, or distillation setups. Its 50ml capacity and narrow neck facilitate controlled reactions, minimal evaporation, and secure sealing via rubber stoppers or PTFE adapters. Widely used in pharmaceutical, analytical, and educational labs, this flask excels in titrations, reflux processes, and small-batch synthesis. Advantages include durability, thermal shock resistance, and compatibility with aggressive reagents, though its compact size limits large-volume applications. Designed for standard bench use, it adheres to ASTM/EISO specifications for lab-grade safety.
