Compact refrigerated/heating circulators which can be used on benchtop or in a fume hood, ideal for temperature control of distillation apparatus or mini plant installation. All four models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. The maximum ambient temperature of +40 °C and air cooled ventilation means the units can be positioned alongside other units or directly in a fume hood.
CF30/CF40 models are ideal for routine applications:
Working temperatures up to +150 °C with pressure pump
Splash-proof key pad
LED temperature display with precise PID temperature control
RS232 interface for PC connection
CF31 and CF41 are suitable for demanding applications. Features are the same as CF30 and CF40 and in addition:
Working temperatures up to +200 °C with powerful electronically adjustable pressure and suction pump
