Laboy Glass 1000mL 3 Neck Round Bottom Boiling Flask with 24/40 Center & Side Joints Angled Distilling Receiving Reflux Flask Multi Neck Distillation Apparatus Organic Chemistry Lab Glassware

Laboy Glass 1000mL 3 Neck Round Bottom Boiling Flask with 24/40 Center & Side Joints Angled Distilling Receiving Reflux Flask Multi Neck Distillation Apparatus Organic Chemistry Lab Glassware

• Strategic 3-Neck Design for Multitasking: Features a center neck and two angled side necks to allow simultaneous heating, reagent addition, and temperature monitoring. Ideal for complex organic synthesis and reflux reactions.
• Extra Heavy Wall Construction: Hand-blown from high-quality Borosilicate 3.3 glass. The heavy-duty wall thickness (3.5mm-5mm) provides superior mechanical strength and resistance to breakage compared to standard economy glassware.
• Universal 24/40 Joint Compatibility: Precision-ground 24/40 standard taper joints ensure a vacuum-tight seal. Perfectly fits standard 24/40 condensers, thermometers, and stoppers for a leak-free setup.
• Annealed at 560°C for Stability: Proper annealing at 560°C removes internal stress, ensuring the flask can withstand rapid thermal changes (thermal shock) and direct flame heating without cracking.
• Professional Lab Standard: Meets ASTM E438 standards. The round bottom shape ensures uniform heat distribution, making it the reliable choice for educational labs and professional research.
