Know for its iconic design and the clean, sediment-free coffee it yields, the Chemex Coffee Maker is the perfect mixture of style and chemistry. The six cup model can make up to 30 ounces of coffee and is perfect for brewing for 1-3 people, while the 3-cup yields 15 ounces. Simple function and visual elegance combine for the optimum extraction of full rich-bodied coffee. This hourglass shaped flask is made entirely of glass, a chemically inert material that does not absorb odors or chemical residues.
