Flasks for use in rotary evaporators are supplied at Avantor. Flasks of borosilicate glass in an array of capacities are offered. Receiving flasks feature ball or socket joints and a choice of jacketed, coated, non-coated, or amberized versions. Large scale options are offered as well. Evaporator or drying flasks are supplied with baffles indented into the glass for better circulation. Large scale models have welded necks to prevent "rotational whip." Rotary evaporator flasks can be purchased individually.
