Laboy Glass 500mL 2-Neck Round Bottom Boiling Flask, Heavy

Laboy Glass 500mL 2-Neck Round Bottom Boiling Flask, Heavy Wall Borosilicate, 24/40 & 24/40 Standard Taper Joints, Angled Side Neck for Distillation, Reflux & Vacuum
- Professional Grade Heavy-Wall Borosilicate Glass: Crafted from high-quality Borosilicate Glass 3.3, this flask features a round bottom shape for uniform heat distribution. It is designed to withstand extreme temperature changes, thermal shock, and pressure differentials, making it ideal for professional laboratory vacuum applications and vigorous heating.
- Optimized 2-Neck Configuration: Features a streamlined 2-neck design that balances functionality and workspace efficiency. The vertical center neck handles the main distillation head or reflux condenser, while the auxiliary neck allows simultaneous temperature monitoring, gas inlet, or reagent addition without the bulk of a 3-neck flask.
- Precision Engineered 25° Angled Side Neck: The side neck is strategically angled at ~25 degrees to maximize ergonomic access and safety. This specific angle utilizes gravity to prevent liquid backflow into thermometers or addition funnels, ensuring accurate readings and preventing cross-contamination during complex multi-step reactions.
- Universal 24/40 Interchangeable Joints: Equipped with precision-ground 24/40 center and 24/40 side standard taper joints. Fully compatible with a wide range of lab glassware accessories, including Liebig condensers, Graham condensers, and Vigreux columns for organic synthesis.
- Hassle-Free After-Sales Support: We pack with extra care using reinforced boxes. However, if your flask arrives broken due to shipping, please contact us directly for an immediate replacement or refund—no return required. We are here to ensure your experiments proceed without delay.
This multi-neck flask has two standard taper ground joint on the Centre neck and the side angled neck. With 2 necks having the same joints Laboy glass flasks are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
