Round-Bottom Flask made of Borosilicate Glass 3.3 with Fused-on Sleeve

The round-bottom flask with sleeve is a high-quality laboratory vessel made of borosilicate glass 3.3 , specifically designed for professional syntheses, distillations, and a wide range of chemical applications. The durable glass is characterized by excellent thermal shock resistance, high chemical resistance, and outstanding transparency, ensuring consistently reliable performance even under demanding conditions.

The fused sleeve ensures a secure, low-stress, and absolutely leak-proof connection with standard ground-glass components such as condensers, adapters, distillation bridges, stirrers, or thermometers. Manufactured with precision according to common laboratory standards, the round-bottom flask is fully compatible with commercially available glassware and is ideally suited for modular apparatus.

The uniform wall thickness gives the round-bottom flask high mechanical stability, allowing it to be used reliably even with direct heating, in oil baths, or in reflux reactions. This makes it particularly suitable for syntheses, sample preparations, extractions, and thermal processes.

Whether in research, education, synthesis laboratories, or analytical facilities – this round-bottom flask impresses with its durability, precision, and safe handling. It is an essential piece of equipment for any professional laboratory that values robust, high-quality glassware.
