A condenser for distillation is a cooling device that transforms hot vapors from boiling a liquid mixture back into a liquid (condensate) by removing heat, allowing for the separation and collection of pure components based on their different boiling points, commonly using cool water circulating through a jacket to cool the inner tube where vapors pass. Key types include the Liebig (simple double-walled tube) for general use and Graham (coiled inner tube) for greater surface area, essential for lab-scale or industrial purification in pharmaceuticals, chemicals, and research
