The Petite Fleur models are the smallest dynamic temperature control systems in the Unistat® range. They are designed for highly accurate temperature control of small research reactors. As all Unistat® models, the Petite Fleur models feature unique thermodynamic qualities that allow the fastest and most accurate temperature regulation. All versions are incredibly space-efficient, simple to use, and adaptable. Environmentally friendly natural refrigerants are already standard on all models.
The Petite Fleur models reach operating temperatures of -40 °C to +200 °C and offer a refrigeration capacity of 480 W (with full pump capacity acc. to DIN 12876). With a capacity of 25 l/min, the circulation pump provides for optimum heat transmission. Delicate glass reactors are protected from damage with the soft start-up, and changes in the viscosity within the fluid circuit are compensated for.
A TFT color display, a programmer, calendar/clock capabilities, user menus, a graphic display, a ramp function, calibration, and many other features are included in the Pilot ONE "Professional" controller, which may be taken off as a remote control.
