Cooling Jacket Accessory
The TGA Cooling Jacket Accessory allows cooling of the TGA 8000 and Pyris 1 TGA furnace
chamber. The cooling jacket is double-walled glassware through which cooling water or
antifreeze flows. For subambient operation, this accessory is to be used with a refrigerated
coolant circulator. The recommended cooling device from PerkinElmer is the Polyscience
Chiller (P/N N5370220/1). Note that a cooler that generates excess vibration or turbulence
may result in the poor performance of the TGA.
