SEPARATING FUNNEL WITH GLASS STOPPER
“Cowbell” separating funnel takes the shape of a cone with a hemispherical end. It has a stopper at the top and stopcock (tap), at the bottom. Separating funnels used in laboratories are typically made from borosilicate glass and their stopcocks are made from glass or PTFE. Typical sizes are between 30 ml and 3 L. In industrial chemistry they can be much larger and for much larger volumes with glass stopper.
