The Nitro is a smaller, 21-inch (about 53 cm) version of the F1 system, likewise with a glass vase and stainless steel internal parts. The kit matches the F1: interchangeable downstems of different diameters, a silicone-cased crystal bowl, a medical-grade silicone hose, gravity tongs, a charcoal tray, eight blow-off purge valves, and an LED vase light with remote (batteries sold separately). It is available in black, blue, and red, and the stem and vase are also sold separately.
