Condensers, Double Surface, ground joint: 19/26, 200 mm-2641087 is a product from Borosil. Laboratory condensers are special glassware which are designed for special experiments such as distillation. The condensation reaction involves cooling of gaseous substances to allow it to condense to its liquid state. In their most simple design, condensers have a long cylindrical tubular structure with an inner tube and an outer tube. The gas which needs to be condensed will be passed through the inner tube and the coolant will be passed through the outer tube. Condensers, Double Surface, ground joint: 19/26, 200 mm-2641087 from Borosil is mainly designed for research labs wherein extremely volatile gases must be condensed. It has the following features:

- These condensers are double-surfaced and has two water jackets. One of the water jackets run on the outside of the central tube containing the gas to be condensed. The other water jacket runs in the central of the condensing tube.

- It is used for the distillation of the following gases
Alcohols
Ethers
Aromatics
Petroleum
Essential oils
