Product Description

The 300ml small-mouth flask (Triangular lab flask 300ml) is a heat-resistant borosilicate glass vessel designed for precise chemical mixing and heating applications. Featuring a compact Small-neck Erlenmeyer flask design with 24/29 standard ground joint compatibility, it operates within -20°C to 400°C thermal range. Its narrow 25mm neck diameter enables controlled pouring and reduced evaporation, while the conical base ensures stable vortex mixing. Ideal for pharmaceutical, analytical chemistry, and educational laboratories, this 190mm-tall flask combines chemical durability with compatibility for clamp connections and condenser attachments. Key advantages include thermal shock resistance and space-efficient design, though its restricted neck may challenge bulk material transfers. Complies with ASTM E438 standards for laboratory glassware safety.
