Borosil Liebig Condensers have an interchangeable inner and outer joint with a drip tip. This simple design has a thin wall for the inner tube, facilitating efficient heat transfer with a low cooling capacity. Most common forms of use are distillate separation. The outer glass tube has two hose connections to assist in the passing of coolant to help attribute to the cooling of hot vapors and liquids for the extraction of solvents. Avail. in Jacket size of 200-400 mm. In collaboration with Borosil Glass Works, Foxx Life Sciences is proud to bring the outstanding quality of Borosil Type 3. 3 Low-Expansion Borosilicate glassware to North America. Manufactured from the same USP Type 1 borosilicate glass that North American scientists have come to trust, Borosil Laboratory Glassware offers unparalleled mechanical strength, clarity and reliability at competitive prices. And thanks to a unique annealing process, Borosil Glassware is stress-free and incredibly resistant to thermal shock.
