Revolutionary Design

Professor Kirsten revolutionized pipesmoking by creating the Radiator stem. When tobacco, which is 30% to 60% moisture, is lit in the bowl, it creates steam. As the smoke is drawn through the stem, the steam is cooled and condenses into a liquid. This bitter-tasting liquid is trapped in the stem, along with tars, nicotine and tongue-biting acids.

Only clean, cool, moisture-free smoke passes through the intake tube to the mouthpiece. To remove the trapped liquid, you simply remove the valve. You can clean a KIRSTEN in seconds by pushing a tissue through the bore of the stem, exactly as you would clean a gun barrel.
