Consumables

The three-neck round bottom flask features a spherical body with three neck openings, allowing multiple reagents or laboratory accessories to be connected simultaneously, such as condensers, dropping funnels, thermometers, or other glass apparatus. The narrow neck design helps reduce solution splashing and evaporation during experiments.

This flask is widely used in chemical synthesis, distillation, reflux, heating, and long-term reaction processes. The round bottom structure provides uniform heating performance and is suitable for use with heating mantles or laboratory heating equipment.

Compared with beakers, the flask has no pouring spout, helping minimize liquid residue and improve reaction stability. The flask can also be used with rubber stoppers and stirring devices for convenient laboratory operation. During heating or reflux experiments, a magnetic stir bar can be placed inside the flask for efficient mixing.

Available in straight neck and angled neck designs to meet different experimental requirements.
