A graham condenser has a coolant-jacketed spiral coil running the length of the condenser serving as the vapor–condensate path.It consists of an inner spiral surrounded by an outer jacket tube.It maxmises collected condensate because all the vapors must flow through the entire length of the spiral,thereby having prolonged contact with the coolant.
Graham condenser also called Inland Revenue condenser,usually used in the downward distillation or vacuum evaporations , installed vertically to prevent liquid pooling in the tube. It is very similar to the coiled condenser but differentiated by an inverted coolant/vapor configuration(the coolant flows through the inner coil and the substance condenses inside the outer tube).
Laboy Graham condenser is designed with standard taper joints at top and bottom to fit the distillation flask and other lab jointed glassware apparatus,with glass hose connections or removable hose connections as the option for water in and out.
Made of high quality borosilicate glass 3.3 having very low?coefficients of thermal expansion for resistance to heat, and a very high resistance to chemical attack.Annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
