Your Evaporation Guide - Evaporating flask size
Achieve higher distillation efficiency when using a rotary evaporator by reading on the impact of flask size.
Generally, the larger the evaporating flask the greater is the evaporation rate. This is due to the greater turbulence inside a larger flask, enlarging the active surface and leading to a higher evaporation output. On the other hand, smaller flasks are advantageous when the residue needs to be collected for further quantitative analyses. Moreover, larger flasks generally allow easier handling.
