Supplier's note

1. Technical Breakthroughs:

   • Borosilicate Glass: Withstands 156°C ΔT in the Pro Model, 30% higher than industry benchmarks, enabling safe use in extreme conditions.
   • Triple-Neck Design: The 40/38 top joint allows direct attachment to condensers, while the dual 24/29 ports enable simultaneous monitoring or additive delivery.
   • 5000 mL Capacity: Doubles the volume of standard 2500 mL flasks, reducing scaling-up costs for industrial labs.

2. Optimal Version Selection:

   • Base Model: Ideal for academic labs or small-scale research with standard chemical handling.
   • Advanced Model: Suited for industrial R&D requiring frequent thermal cycling (e.g., pharmaceutical synthesis).
   • Pro Model: Essential for facilities handling aggressive chemicals (e.g., concentrated acids) or requiring high-precision distillation setups. With its tripled chemical resistance, the Pro Model ensures safety in scenarios where cross-contamination risks are critical.
