The 4-Neck Round Bottom Boiling Flask is a sophisticated laboratory vessel designed for complex multi-step chemical reactions. Featuring a classic round body and a vertical center neck, it is equipped with three additional side necks (available in both Straight/Vertical and Oblique/Angled configurations).

This multi-neck design allows for the simultaneous integration of multiple laboratory components, such as reflux condensers, thermometers, addition funnels, and stirring shafts, or for the concurrent introduction of various reagents. The narrow-mouth design effectively prevents liquid splashing and minimizes solvent evaporation during prolonged heating or refluxing. The round bottom ensures uniform heat distribution, making it ideal for use with heating mantles.

Key Features & Advantages

Precision Ground Joints: Each neck features a high-quality ground glass joint with standard size markings (e.g., 24/29, 19/26). This ensures airtight, vacuum-secure connections with other glassware and provides maximum convenience for experimental setup.

Clear & Permanent Markings: Capacity and material specifications (Boro 3.3) are printed using high-contrast, wear-resistant ink, ensuring long-term visibility and providing accurate data for your experiments.

Smooth & High-Grade Finish: The entire flask body is manufactured with superior craftsmanship, resulting in a smooth, protrusion-free surface that is easy to clean and aesthetically professional.

Excellent Thermal & Chemical Resistance: Crafted from Premium Borosilicate 3.3 Glass, the flask offers exceptional resistance to thermal shock and chemical corrosion, specifically designed for high-heat laboratory applications.

Flexible Configurations: Available in Straight/Vertical or Oblique/Angled side neck arrangements to accommodate different stirring and apparatus alignment requirements.
