Round Bottom Flask, Single Neck with Joint

Crafted from high‑purity borosilicate glass, this 250 mL round‑bottom flask features a uniform spherical body for optimal heat distribution and a standard 24/29 ground‑glass neck joint for secure, leak‑free connections. Ideal for distillations, reflux reactions and heating under mantle or oil bath, its seamless construction resists thermal shock and chemical corrosion, making it a reliable workhorse for organic synthesis and preparative chemistry.
