NOTICE1. Borosilicate glass will begin softening above 800 °C (~1500 °F). Any temperature below this should be a good operating temperature;2. The temperature differential that borosilicate glass can withstand before fracturing is about 165 °C (329 °F).PACKAGEYoung4us Glass Erlenmeyer Flasks x 3Young4us Rubber Stoppers for Erlenmeyer Flask x 3 Review: Lab-Quality - Used these for an experiment.
