This is a variable temperature cell which permits transmission mode measurement of solid and liquid samples with gas exchange capabilities across the face of a solid sample.
This is a variable temperature cell which permits transmission mode measurement of solid and liquid samples with gas exchange capabilities across the face of a solid sample. The cell consists of a vacuum outer jacket and a cold finger that may be cooled with liquid refrigerant. Sample cells are inserted into a block attached to the cold finger fitted with heaters to maintain precise temperature control. The external vacuum jacket windows are heated to prevent condensation at sub-ambient temperatures. The sealed or demountable liquid cell asssembly can be converted to a flow cell configuration with the appropriate attachment. Two fixed thermocouples are installed to monitor the temperature of the cell holder and the outer jacket window assembly. A spare thermocouple can be introduced to accurately monitor the sample temperature. The cell can be configured for UV-Vis and Fluorescence applications.
Options available include liquid sealed and demountable cell configurations, solids cell, gas exchange solids cell, flow through cells, high pressure cells and a variety of window materials to assemble within these cells. Additional options represent a choice of temperature controllers for 110V or 220V operation with or without an RS-232 computer interface. Request a catalog for a complete schedule.
