Laboy Glass 1000mL 2-Neck Round Bottom Boiling Flask, Heavy Wall Borosilicate 3.3 with 24/40 Center & Angled Side Joints, Heating/Reaction Flask for Organic Chemistry

• DESIGN – 2-NECK ROUND BOTTOM 2-neck round bottom boiling flask with one center neck and one angled side neck, both with 24/40 standard taper outer joints. The round bottom shape distributes stress evenly and is ideal for uniform heating and vacuum applications.
• SIZE & COMPATIBILITY – 1000 mL, 24/40 JOINTS 1000 mL capacity suitable for medium-scale reactions and solvent volumes. Both 24/40 joints are fully interchangeable with standard 24/40 condensers, adapters, thermometer joints, addition funnels and other jointed glassware used in organic chemistry labs.
• VERSATILE LAB USES Designed for heating, reactions and distillations. The center neck typically connects to a distillation head, reflux condenser or three-way adapter, while the angled side neck provides an extra port for a thermometer adapter, gas inlet, inert gas line or addition funnel in multi-step or stirred reactions.
• MATERIAL & WORKMANSHIP – HEAVY-WALL BOROSILICATE 3.3 Hand-blown from heavy-wall borosilicate 3.3 glass and annealed at high temperature to relieve internal stress. Thick, durable walls offer excellent resistance to thermal shock, chemical attack and mechanical stress, allowing direct flame heating and repeated heating–cooling cycles.
• KEY ADVANTAGES Combines the even heating and vacuum performance of a round bottom flask with the flexibility of two necks for more complex setups. Durable, reusable and fully compatible with standard 24/40 systems, it is a practical, long-lasting choice for teaching laboratories, research labs and general organic synthesis.
