Laboy 500mm Graham Condenser with 24/40 Joints - 10mm Glass Hose Connections - Premium Lab Glassware for Distillation & Chemistry Experiments - Perfect for Home Brewing, Essential Oil Extraction & Scientific Research

The “graham-style”condenser having the configuration that the jacket tube contains coolant,and condensation takes place inside the inner tube or coil includes Liebig condenser,Allihn condenser,West condenser,Graham condenser. 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.

The joint size is described by the form A/B. The first number A represents the outer diameter (OD) in millimeters (mm) at the widest point of the inner (male) joint and the second number B represents the length of the joint. For example, a 14/20 joint is 14 mm wide at the top (the widest part) and is 20 mm in longth. The joint has a standard taper 1:10, any two joints (male and female) with the same outside diameter (A)can fit into each other ,no matther how lenght the joints are. For example, a 24/40 (US standard size) joint on a condenser will fit into a 24/29 (European standard size)flask but the ground glass joint will protrude (40 - 29) 11mm into the flask.
