Round Bottom Flask, Two-Neck, Angular, ASTM

Round Bottom Flask, Two‑Neck, Angular, ASTM from OsmosisScientific is a borosilicate 3.3 distillation and reaction flask designed for demanding synthesis, reflux and solvent‑recovery work. The round bottom provides uniform heating in mantles and baths, while one vertical centre neck and one angled side neck with ASTM standard ground joints allow easy connection of condensers, thermometers, addition funnels or gas inlets in a compact setup.

Note: This Round Bottom Flask, Two‑Neck, Angular, ASTM is built to ASTM and USP dimensional standards but is supplied without an individual batch or calibration certificate, making it ideal for routine synthesis and distillation where certified volumetric traceability is not required.
