Mounting the Cooling Head
The LN Pump unit connects to the DSC cell via a cooling head. This cooling head is made up of an internal
heat exchanger, anti-condensate heaters, and various other components. The following steps describe the
procedure for making the connection between the DSC and the LN Pump unit.
CAUTION: Before beginning, ensure the cell is at a temperature where contact with the cell will not
cause a burn.
MISE EN GARDE: Avant de commencer, assurez-vous que la cellule est à une température où le
contact avec la cellule ne sera pas provoquer une brûlure.
1
Verify that the DSC cell surface (indicated in the figure below) on the top of the silver block is not
damaged or compromised. If any irregularities such as dents, buildup, contaminants, or oxidation are
observed in the silver, contact your local TA Instruments Service Representative for details on re-dressing
the cell.

Verify that the DSC cell cooling flange is not damaged or compromised. Also inspect the graphite gasket
that is installed on the mating surface of the copper heat exchanger in the LN Pump cooling head. If any
irregularities such as dents, buildup, contaminants, or oxidation are observed, contact your local TA
