Why Three Parallel Necks
A parallel three-neck arrangement keeps all three necks vertical rather than angled, which suits reaction set-ups that need a stirrer running through the centre neck while a condenser and an addition funnel or thermometer occupy the two side necks. This flask covers a working range from 100ml lab-scale reactions up to 2000ml for larger batches, with matched socket sizes across all three necks.
