Chemglass 2 Neck Heavy Wall Round Bottom Flask 19/22 CN 14/20 SN 100 ml Angled

The Chemglass CG-1520-50 is a specialized 2-neck heavy-wall round bottom flask designed for high-performance laboratory applications. Its mismatched joint sizes and heavy-wall construction make it ideal for microscale to small-scale synthesis where durability and versatile component fitting are required. The combination of a 19/22 center neck and a 14/20 side neck allows you to use standard 19/22 condensers or stirrers while utilizing smaller 14/20 accessories like addition funnels or thermometers without needing adapters. The angled design ensures that accessories in the side neck do not interfere with the center neck assembly, providing a more ergonomic and space-efficient setup. Highly resistant to most acids, alkalis, and organic solvents, ensuring long-term reliability in aggressive chemical environments. Some of the common applications for this flask include vacuum distillation, air-sensitive chemistry, and controlled reactions.

Used, in great condition.
