RT2 Plus Advanced hotplate stirrer for laboratory use

Firstly, the Thermo Scientific RT2 Plus Advanced hotplate stirrer is the most advanced digital hotplate stirrer in the RT series. Moreover, this model combines a 140 mm round ceramic heating surface with microprocessor PID control and an included PT100 temperature probe. As a result, the unit controls the actual liquid temperature instead of the plate surface temperature. In addition, the RT2 Plus Advanced offers a unique wide stirring range of 30 to 2000 rpm for both extremely slow and powerful mixing.

Included PT100 temperature probe for liquid control

Firstly, the RT2 Plus Advanced is supplied as standard with a PT100 temperature probe (B Class, 250°C) for direct liquid measurement. Secondly, the unit controls the actual temperature of your sample in real-time with this probe. In addition, the PT100 offers more accurate control than plate temperature measurement alone. Moreover, an optional PT100 A Class probe is available for temperatures up to 400°C.

Feedback control during viscosity changes

Firstly, the unit controls both temperature and stirring speed in real-time with PID feedback. Secondly, the feedback function maintains the set stirring speed stable, even when the viscosity of your sample changes during heating. In addition, this is ideal for reactions where the composition changes due to temperature effect. Moreover, you can manually set the heating power from 0 to 100% in 1% increments.

Three selectable control modes for optimal flexibility

Firstly, the Optimal Mode offers balanced heating for general applications. Secondly, the Fast Mode speeds up the heating process when time is critical. In addition, the Slow Mode guarantees gradual heating for temperature-sensitive samples. Moreover, you combine these modes with the programmable timer for reproducible protocols.

Integrated safety features

Firstly, the over-temperature protection shuts off the heating element when the surface approaches 450°C. Secondly, the HOT TOP indicator activates a clear warning signal when the plate is hot. In addition, you can set a maximum temperature limit yourself for extra control in sensitive applications. Moreover, the keypad lock prevents settings from being changed unintentionally during running experiments.

The RT2 Plus Advanced hotplate stirrer is widely used in the pharmaceutical industry and biotech, medical diagnostics, food industry and agriculture and horticulture. For advice, please contact Poly Temp Scientific.
