There is a steam distillation but no sloping splash head?

Steam distillation is specifically used for temperature sensitive materials such as natural aromatic compounds. When you add steam it allows them to evaporate at lower temperatures.

Otherwise it wouldn't be a STEAM destillation, would it?

Type, 'Steam Distillation Sloping Splash-head' into Google and hey presto, lot's of links.

Simple and steam distillation are similar in that they use boiling to separate organic components. Simple distillation boils them off at their boiling points, then condenses them. Steam distillation uses water mixed with the compounds to lower their boiling points and avoid decomposing them by heat.
