Conical flask with ground section 14/23

Conical Flask with Ground Section 14/23

The Conical Flask with Ground Section 14/23 is a laboratory vessel manufactured from borosilicate glass and fitted with a standardised 14/23 ground glass joint. Its conical (Erlenmeyer) shape combines a wide base with a narrow neck, making it a versatile container for mixing, heating, titrating, and storing liquids. The ground joint at the neck allows the flask to be connected securely to other ground-glass components, stoppers, or apparatus that share the same 14/23 standard taper.

Material and Construction

This flask is made entirely from borosilicate glass, a material valued in laboratories for its durability and stability under changing conditions. The glass offers a temperature resistance of up to 500°C and is resistant to most acids and alkalis, allowing the flask to be used with a broad range of chemical reagents. The precision-ground 14/23 joint ensures a reliable, well-fitting connection with matching glassware, helping to maintain a closed system during reactions or distillation setups.

Applications and Related Glassware

Thanks to its standardised joint, this conical flask is well suited to assembling distillation, reflux, and other interconnected glass setups. The wide base supports stable placement and swirling of contents, while the narrow neck reduces evaporation and splashing and accommodates ground-glass stoppers or adapters. The flask can be used for general sample preparation, mixing of solutions, and titration work where a ground neck connection is preferred over an open-mouth design.

Laboratories building a complete set of compatible vessels can pair this item with the matching 14/23 ground-mouth flask range to ensure interchangeable joints across an apparatus. For applications that do not require a ground joint, the open-mouth Conical Flask offers a simple alternative for routine mixing and storage. When a stable, broad-based vessel with a joint is needed for boiling or heating procedures, the Flat-Bottom Flask with Joint is a complementary option that shares the same ground-glass connection principle.

The combination of borosilicate construction, a precise 14/23 joint, and a choice of capacities makes this conical flask a practical component for many standard laboratory procedures. Available soon.
