The PAF 110/8 series is specifically designed for ashing under difficult conditions in the laboratory environment. The unique features of this series are the Quartz tube, which allows for the protection of the heating elements, and the preheated air inlet system for better ventilation. The lid of this series also opens sideways allowing the user to operate the furnace within a fume hood where there is limited space. The double walled structure and safety switch is standard, as in all Protherm furnaces and the same range of controllers as used in their other furnaces can be applied to these furnaces as well. There are seven models available within this range and Protherm is represented by Air & Vacuum Technologies.
