Making coffee can seem like a scientific experiment. It is. But don't worry, the siphon is a very simple device that was invented in the early 19th century. Technica combines beautiful craftsmanship, minimalist design and amazing functionality. The siphon works according to the basic laws of physics. Fill the lower chamber with water, which flows into the upper chamber with ground beans when heated. After a few minutes, disconnect the heat source and the coffee passes through the filter into the lower chamber. It is ready. Capacity: 240 ml. The set includes an alcohol burner. We also offer a Rekrow gas burner and a Harry halogen heater.
