Cooling Devices
Several types of cooling devices are available for use with your Pyris Series Thermal Analysis System. The types of experiments you perform will determine the coolant or cooling accessory you should use.

A Reservoir Kit is available for the DSC 7. This reservoir can be used for an ice bath or for liquid nitrogen.
The Pyris 1 DSC is shipped with an ice water container that can be used with the cold finger. The cold finger is
already attached when the Pyris 1 DSC is shipped.
The DSC 7, the Pyris 1 DSC, the DMA 7/7e, and the TMA 7 are shipped with their own turbulent chamber. It is already attached to the sample holder in the DSC 7. Circulating baths and refrigerated liquid chillers can be attached to the turbulent chambers as well.
The Pyris 6 DSC and the Pyris 6 TGA contain an integrated cooling system with which you can use tap water and refrigerated cooling circulators.
For optimum results, the flow rate of a coolant must be constant and there should not be any air bubbles circulating through the system.
The PerkinElmer Intracoolers 1 and 1P and 2 and 2P provide a convenient means of cooling the sample holder enclosure block of an analyzer. They are closed-loop circulating heat exchangers that contain a compact mechanical refrigeration unit. The refrigerant is a widely available, nontoxic, non-CFC refrigerant that can continuously produce block temperatures as low as –55°C in the case of the Intracooler 1 and –85°C in the case of Intracooler 2. They permit operation of the analyzer to –30°C or –65°C, respectively. The Intracoolers should be placed on the floor either beneath or next to the bench with the analyzer on it.
The lowest temperature obtainable will depend on the ambient temperature and voltage in your laboratory.
Precautions for Liquid Nitrogen Cooling Accessories(Cryofill and CCA)
DO NOT operate the Differential Scanning Calorimeter with liquid nitrogen in an enclosed environment without adequate ventilation
Precautions for Intracoolers
Do not lift or move the unit by pulling the flexible line.
Do not make any sharp bends in the flexible line.
Do not block or restrict air flow to the vents on the unit.
Do not operate the unit in temperatures above 32°C.
Do not operate at a line voltage outside of 110 V +/-10% or 220 V +/-10% when operating at 50 Hz.
A Dry Box Assembly is required when using an Intracooler with the DSC 7.
