Talk:Friedrichs condenser

The picture of the condenser is misleading, because it shows a graham condenser. The Friedrichs condenser: The cooling is not done by a spiral but by a cooling finger, The surface of the coolingfinger, which has a spiral dent from bottom to the top, nearly touches the outer glas jacket. The vapour has to take the long way in this dent between the outer glas surface and the cooling finger. Picture in the web are also sometimes wrong.--Stone 08:13, 18 July 2007 (UTC)
