Wheaton-Hickman flask

In cases where the quantity of material to be distilled is such that there is a danger of drainage of droplets of condensed liquid from the cold finger, a small collection cup may be attached to the cold finger by means of platinum wire suitably fused to the two glass surfaces (Fig. 2.114). Alternatively the Wheaton-Hickman flask (Aldrich) (Fig. 2.115) may be used note in this case the screw thread joint.
