The reflux condenser you described has an outer and inner joint size of 14/20 or 19/22 . The coil section of the condenser is 100mm in height, and it has glass hose connections. The condenser is made by Laboy glass, which is known for producing high-quality borosilicate glassware that is hand-blown to ensure uniform wall thickness. A reflux condenser is a type of laboratory glassware used in chemistry experiments to prevent the escape of volatile liquids during a distillation process. The condenser works by cooling the hot vapor, causing it to condense back into a liquid and flow back into the original flask. This allows for more efficient distillation of the liquid, as it prevents the loss of valuable compounds through evaporation. The glass hose connections on the condenser allow for easy attachment to other pieces of laboratory equipment, such as a heating mantle or a vacuum pump. .
Laboy glass are all made of high-quality borosilicate glass and made by hand-blowing to ensure uniform wall thickness.
