The Campingaz Labogaz 206 is a portable Bunsen burner that runs on a Campingaz C 206 GLS pierceable butane cartridge, for school and university laboratories, jewellers, dental technicians and hobby workshops where there is no fixed gas line. It gives a stable, adjustable flame of about 1100 °C with a power of about 760 W. Gas flow is set with a knurled screw and plug valve, and the air intake is adjusted by turning the metal sleeve on the brass burner tube (21 mm diameter), so you can switch between a hot blue flame and a softer yellow one. The Clip & Go housing makes changing cartridges easy and holds the burner upright; with the foot fitted it stands about 21.5 cm high. Gas use is about 45 to 60 g per hour and the burner weighs about 380 g. Gas cartridge sold separately.
