Cooling
The DSC 4000 incorporates a built-in cooling chamber that lies below and is attached to the
furnace assembly. The chamber uses a simple in/out design which allows for the use of any
noncorrosive circulating liquid or cooling gas. Cooling liquids include water and ethylene
glycol.
For cooling with liquids, many commercial circulating coolers are available that can be
interfaced to the DSC 4000. The Polyscience Chiller (P/N N5370220/N5370221, 120 V and
220 V, respectively) is the recommended cooling device for the range –20 °C to 445 °C. The
Intracooler (P/N N5374098/N5374099) is recommended for the range –65 °C to 445 °C. The
Intracooler accessory allows rapid cooling between sample runs, allowing fast sample
turnaround. The Portable Cooling Device (PCD) can also be used to quickly cool the
DSC 4000 to ambient temperature, or to cool below room temperature for occasional
subambient measurements. The PCD (P/N N5202068) can be filled with ice, ice water, liquid
nitrogen or any other cooling mixtures.
