Product Description

The 250ml small-mouth triangular flask, also known as a lab triangular Erlenmeyer flask, is a precision-crafted 250ml Erlenmeyer laboratory flask designed for chemical mixing, titration, or culturing applications. Its narrow neck minimizes evaporation and splash, while the conical base ensures stable heating on hotplates. Made from high-quality borosilicate glass, it withstands temperatures up to 450°C and thermal shocks. The flask features a 29/32 standard ground joint for secure connections with condensers or stoppers. Ideal for chemistry, biology, and pharmaceutical labs, its graduations (±2% accuracy) enable approximate volume measurements. Advantages include chemical resistance and compatibility with autoclaves, though its fragility requires careful handling. The base diameter is 85mm, height 175mm, with a neck length of 60mm and 19mm opening diameter for controlled pouring.
