- Advanced 4-Neck Configuration: Features one center neck and three angled side necks, offering superior flexibility over standard 3-neck flasks. This design allows simultaneous connection of a condenser, thermometer, addition funnel, and inert gas inlet, eliminating the need for unstable Claisen adapters.
- Heavy Wall & Thermal Stability: Hand-blown from premium Borosilicate 3.3 glass with an extra-heavy wall design. Annealed at 560°C to eliminate internal stress, this flask withstands vacuum pressure and extreme thermal shock, making it ideal for demanding reflux reactions.
- Optimized 20° Angled Side Necks: Unlike vertical necks that cause equipment crowding, our precision 20-degree offset creates maximum clearance. This ergonomic design prevents collisions between funnels and condensers, allowing for safer assembly in compact setups.
- Precision Ground Joints: Equipped with four 14/20 standard taper joints, ground to strict ASTM E676 standards. Ensures a vacuum-tight seal and 100% interchangeability with standard 14/20 lab adapters, preventing leaks during sensitive organic synthesis.
- Professional Lab Performance: Designed for academic and industrial R&D. The direct 4-neck structure provides a more stable, low-vibration geometry compared to stacked adapters, ensuring integrity during long-duration reflux and distillation processes.
