The surface area of the Graham coil condenser is considerably greater than the corresponding Liebig condenser of similar dimensions. The coil condenser is extremely efficient in the reflux mode where counter-current cooling is possible.

Quickfit® jointed glassware from Scilabware is a comprehensive range of laboratory articles with interconnecting joints, enabling simple to complex chemistry set-ups to be easily constructed and allowing a variety of analytical, development or educational tasks to be undertaken. Precision-engineered, ground glass joints with a standard taper and smooth surface ensure complete interchangeability of elements with the same joint size and the highest standards of leak-tightness.

Quickfit® is manufactured in clear, Pyrex® borosilicate glass, with a low coefficient of expansion, excellent chemical and heat resistance. It conforms to the following standards:

ISO 3585, DIN 12217 - Type 3.3 borosilicate glass
ASTM E-438 Type 1 - Class A borosilicate glass
US Pharmacopoeia - Type 1 borosilicate glass
European Pharmacopoeia - Type 1 glass

Further technical details are available on request.

Joint sizes are designated XX/XX, the prefix (XX/-) being the small diameter of the cone or socket and the suffix (-/XX) being the cone or socket height, i.e. size 24/29 has a 24mm diameter at its smallest point and the overall cone or socket height is 29mm.
