Split Tube for Easy Access! • 1200°C max. temperature • 12” (30 cm) or 24” (60 cm) heated zone • Can be operated vertically with optional floorstand Product Description • Our new 12" (30 cm) and 24" (60 cm) split tube furnaces include a built-in temperature controller to conserve valuable bench space. • Units are flexible enough to be mounted horizontally, remotely, or vertically on our optional floor stand (model AY793X1). • Single zone split tube furnaces heat to 1200°C in only 20 minutes. With exposed coil heating elements embedded in state-of-the-art ceramic fiber insulation. • 1, 2, and 3 inch tube chamber collars are included. • No power cord supplied. Electrical connection requires fixed wiring. • No process tubes supplied with furnace. Operation • Choose from 3 temperature control models: B1: Digital single set point control with a single ramp to set point and a dwell. A single display shows actual temperature or set point. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay. C1: Digital programmable control with one stored program of 8 segments. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay. D1: Digital programmable control with 4 stored programs, 16 segments per program. The controller also includes RS232 communications. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay. Safety • A door safety switch turns off power to the heating elements each time the chamber is opened for loading or unloading process tubes. • Over temperature protection safeguards valuable research by permitting you to set the desired maximum temperature. • Single zone split tube furnaces are guarded with thermocouple break protection. In case of an open circuit, power is cut off to the elements to avoid an over temperature situation.
