This Dimroth Reflux Condenser is made of 3.3 borosilicate, heat-resistant glass. Coolant flows through the tightly wrapped inner coil and returns to the top through a central tube. Vapors condense inside the outer tube, which is the reverse of conventional coiled condensers and is considered to be more efficient.
The condenser's water jacket is 300mm (11-3/4") long with 3/8 inch hose nipple coolant connections both at the top. Has a top outer standard 24/40 taper joint and lower 24/40 inner drip tip joint. Overall length is 16-1/4".
