Choosing the Right Socket Size for Your Rotary Evaporator
Rotary evaporators are typically fitted with either a 24/29 or a 29/32 joint on the evaporating-flask side, so matching the socket size to the instrument is essential before ordering. This range covers both socket sizes across most common capacities (100ml, 250ml, 500ml and 1000ml), while the smallest (50ml) and largest (2000ml) capacities are supplied in 29/32 only.
