500ml Round Bottom Borosilicate Glass Boiling Flask

500ml Round Bottom Borosilicate Glass Boiling Flask

The 500ml Simax round bottom boiling flask is designed for controlled heating and evaporation at half-litre scale.

The borosilicate glass 3.3 body withstands repeated heating cycles and prolonged exposure to reagents. A round bottom distributes heat uniformly across larger surface area, improving boil stability and energy transfer. The narrow neck with beaded rim supports safe stopper fit and connection to condensers or adapters. Clear glass aids observation of reflux rate and bumping, and the flask is autoclavable at 121 °C for repeated service.
