500ml Round Bottom Borosilicate Glass Boiling Flask – no sample

500ml Round Bottom Borosilicate Glass Boiling Flask

The 500ml Eisco round bottom boiling flask provides reliable heating capacity for half-litre laboratory applications.

Produced from borosilicate glass 3.3, this flask endures repeated thermal and chemical exposure. The round bottom distributes heat evenly during boiling and reflux, while the narrow neck with reinforced rim ensures safe stopper integration and apparatus setup. The robust, thick-walled design improves impact strength, and autoclavability at 121 °C makes it suitable for repeated use in research, teaching, and industrial environments.
