It are ideal for efficient condensation during laboratory distillation and reflux processes. Featuring a robust double-walled jacket, these condensers ensure efficient heat exchange by allowing coolant to flow through the outer jacket. Constructed from high-quality borosilicate glass, they offer excellent resistance to thermal shock and chemical corrosion. The NS 45/40 socket and cone provide a secure, leak-free connection to other laboratory glassware, while the 250 mm length makes it suitable for a wide range of laboratory applications.
