Flasks & Bottles
Standard 24/40 joint round-bottom flask for reflux, distillation, and rotary evaporation.
A lab staple — our 500ml round-bottom flask is made from borosilicate 3.3 glass with a precision-ground 24/40 joint. The spherical shape distributes stress evenly for safe heating, and the narrow neck prevents splashing during vigorous boiling. Compatible with heating mantles, rotary evaporators, and standard Schlenk line setups.
