Collection: Graham condensers

The graham condenser,  with a spiral coil running the length of the condenser serving as the vapor–condensate path,the coolant liquid went throught the outside area of the condenser.  
It is easily confused with coiled condenser.In a coiled condenser,the coolant liquid went through the spiral oil.The outside area of the condenser will provide more surface area for cooling and for this reason it is most favorable to use.
With standard taper joint at top and bottom,for easily fitting with distillation adapter and take-off adapter.The most joint sizes are 14/20,19/22,24/40.
