The latest differential scanning calorimeter series.
The sensitivity, the baseline stability and the temperature control performance of the DSC7000 series largely improved.
With wealth of option line-up, it has versatile expandability to realize automatic measurement, photochemical reaction measurement and the sample observation measurement.
It is most suitable for measurement of melting, glass transition, crystallization, curing, specific heat capacity measurements and purity analysis of a very small amount of samples in fields such as polymer materials, inorganic materials, pharmaceutical products and food.

New sensor achieves tripled sensor sensitivity by the multiple thermocouples (compared to the conventional products of Hitachi High-Tech Science).
New furnace which is composed of 3 layer insulation wall and the optimized heating and cooling structure suppresses the influence of baseline fluctuation, and increases temperature following capability. These achieve world' s leading performance of DSC sensitivity less than 0.1 µW (RMS noise less than 0.05 µW) and baseline repeatability ±5 µW. It enables the more reliable. (DSC7000X)
New furnace delivers the expanded temperature range up to -80 to 500°C in case of using the Electrical Cooling Unit. Cooling control performance enables down to -50°C at 10°C/min linearly. (DSC7000X)
The Auto LN2 Gas Cooling Unit improves the cooling efficiency and the amount of LN2 used decreased.
Newly designed cooling systems including Auto LN2 Gas Cooling System and Electronic Cooling System are available for the DSC7000 Series. The cooling performances of both systems are improved.

The above is a comparison of 1st and 2nd heating DSC curve of PET. In the 2nd heating (lower), Tg and cold crystallization peak are observed since the sample was converted to amorphous after rapid cooling.
This shows the DSC results for In35Bi2SnNi solder at different composition ratios. Unlike the eutectic melting peaks, there are differences in the solid-phase melting.
This is a comparison of DSC curves of three types of chocolates. The melting temperature varies according to cacao butter content.
This shows thermal denaturation measurements of 1% Lysozyme and Myoglobin solutions. DSC can be used to evaluate thermal stability of protein.
