Borosilicate Round Bottom Flask 250 ML (29/32 Joint) – Pack of 2

The Borosilicate Round Bottom Flask (250 mL) with a 29/32 joint offers superior thermal performance and precision in experiments involving chemical reactions, extractions, or distillations. The 29/32 joint is industry-standard, enabling easy and secure connection to other lab glassware such as condensers and adapters. Constructed from thick-walled borosilicate glass, the flask resists cracks and breakage under repeated heating and cooling cycles. It’s ideal for use in reflux setups, rotary evaporators, and other systems requiring reliable thermal stability. The round bottom design improves heat circulation, making it efficient for boiling under controlled lab conditions. A pack of 2 provides added utility and convenience. This product is a go-to for chemists, lab technicians, and students requiring consistent, high-quality performance in experimental work.
