Why a 12L/22L Two-Neck Flask Is Specified
Standard laboratory round bottom flasks are typically sized well under 5 litres; the 12L and 22L capacities of this flask are aimed at large-volume reaction, reflux and distillation setups where a bigger main vessel is needed alongside a second access point. The 100mm center neck carries the main apparatus connection, while the 24/40 side neck accepts compatible adapters, condensers, thermometers or addition funnels — buyers should confirm glass wall thickness and pressure/vacuum suitability for their specific large-volume application at enquiry stage.
