This syphon vacuum coffee maker brews coffee by siphoning. Water in the lower glass bowl is heated, and the pressure pushes it up into the upper chamber, where it mixes with the coffee grounds. When the heat is removed, a vacuum draws the brewed coffee back down through a filter into the lower bowl.
It is made of heat-resistant borosilicate glass, which is built to withstand direct heat sources such as an alcohol burner or a halogen beam heater. A rubber sealing ring keeps the brewing airtight and is odor-free. It comes in 3-cup and 5-cup sizes, and the two differ only in chamber dimensions.
The smooth glass construction comes apart into upper and lower chambers for cleaning. The design is lightweight and compact.
