Mettler Toledo has launched HS82 and HS84 hot stage systems that are designed to offer easy to understand and simple to operate solutions for temperature control or heat flow measurement under a microscope.
Their dual heater furnace design is said to guarantee outstanding temperature uniformity in the sample.
The new controller offers a One Click operation and flexibility – method programing with up to 99 isothermal and dynamic temperature segments.
The HS82 hot-stage system is used where the temperature of very small samples has to be regulated in a limited space and where the samples have to be observed at the same time.
It records changes in the appearance of the sample and the calorimetric behavior simultaneously.
The heart of all hot-stage systems is the furnace with a heating element beneath and above the sample, which offers temperature uniformity in the sample.
The HS 1 control unit is equipped with a wide color touchscreen, which allows intuitive operation with a finger and delivers clear information to the user.
If repetitive measurements are required, one press of a key (One Click) is sufficient to start a stored method.
The possibility to pause or accelerate the temperature program or switch to cooling during the running measurement using the buttons on the touch screen or the manual keys gives full temperature control to the user.
Thermal events can be marked on the temperature curve.
An access to the sample chamber from above means that the sample can be easily inserted and, if necessary, mechanically manipulated.
With 56 thermal elements, the FRS5 ceramic sensor in the HS84 is highly sensitive and has unprecedented temperature resolution.
It is suited to all possible applications of the Differential scanning calorimetry (DSC) hot-stage.
The evaluation of the DSC curves measured with the HS84, graphical processing, and documentation are made possible using the evaluation window of the STARe software.
