Round Bottom Flask with three necks

Round Bottom Flask with Three Necks - Professional Laboratory Glassware

Our round bottom flasks with three necks are essential multi-port reaction vessels designed for complex synthetic chemistry and advanced laboratory procedures. These precision-engineered borosilicate glass flasks feature three standard taper ground glass joints, enabling simultaneous connection of multiple accessories such as condensers, thermometers, addition funnels, and gas inlet tubes for sophisticated chemical reactions.

Key Features

• Triple neck configuration with standard taper joints (14/20, 19/22, 24/29, 29/32)
• Heavy-wall borosilicate glass construction for superior chemical resistance
• Uniform wall thickness ensuring optimal heat distribution
• Annealed stress-free glass preventing thermal shock
• Compatible with standard laboratory clamps and heating mantles
• Available in volumes from 25mL to 5000mL

Applications

These three-neck round bottom flasks are indispensable for organic synthesis, reflux reactions, distillations with monitoring capabilities, inert atmosphere work, and multi-step chemical processes. Ideal for pharmaceutical research, academic laboratories, and chemical manufacturing where precise control and monitoring are crucial.

Technical Specifications

Manufactured from Type I borosilicate glass with low thermal expansion coefficient (3.3 x 10⁻⁶/°C), these flasks withstand temperatures up to 500°C and provide excellent chemical durability. Each flask undergoes rigorous quality control testing to ensure dimensional accuracy and joint compatibility with standard laboratory equipment.
