Differential Scanning Calorimeter DSC7000 Series
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.

Features
1. Highest sensitivity, superior baseline stability and repeatability
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)
2. Superior Temperature Followability
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.
3. Improved Cooling Performance
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.
4. Excellent Expandability and Option Line-Up
- The auto sampler can be attached easily. The reliable routine measurement can be achieved by the combination of the Auto Sampler and the Mass Flow Controller.
- The photochemical reaction measurement can be achieved by attaching UV irradiation unit.
- The DSC7000 series can observe a sample with a continuous image during the measurement by the Real View Sample Observation Unit.

Applications
Polyethylene terephthalate (PET)
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.
Lead-free Solder
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.
Chocolate
This is a comparison of DSC curves of three types of chocolates. The melting temperature varies according to cacao butter content.
Protein
This shows thermal denaturation measurements of 1% Lysozyme and Myoglobin solutions. DSC can be used to evaluate thermal stability of protein.
DSC7000X achieves unbeatable DSC sensitivity and repeatability with a superior new sensor and furnace. Hitachi High-Tech Science supplies the state of the art DSC for real experts.
DSC7000X improves the reliability of data due to the superior sensitivity and repeatability with enhanced expandability. DSC7000X is ideal for a variety of applications including small samples, real-time sample observation and photochemical reactions as well as general DSC measurements.
