Jointed (24/40) Erlenmeyer Flasks

United Scientific Jointed Erlenmeyer Flasks are designed for reliable mixing, heating, swirling, storage, and reaction workflows that require a standard ground glass connection. Each flask features a 24/40 jointed socket, making it easy to connect compatible stoppers, adapters, condensers, and other laboratory glassware components.

Manufactured from ASTM E-438 Type I Class A borosilicate 3.3 glass, these flasks provide an excellent balance of thermal shock resistance and physical strength. Durable white enamel graduations support quick volume reference, while ground joints manufactured to ASTM E-1404 Type 2 Class 1 requirements give labs dependable compatibility and performance.
