Introduction
The Vial Heater Module is designed to operate with the Metrohm NIRS XDS monochromator,
equipped with the Optiprobe Module configured for transmission operation. The Vial Heater provides
a consistent sample temperature for optimum repeatability of sample spectra.
The Metrohm NIRSystems Vial Heater Module provides a means to pre-heat samples and controls
their temperature during the data collection process. Controlled temperature can be selected and
maintained above room temperature, and below 200 °C.
The Vial Heater Module consists of a temperature control unit and a vial heater block. The display
reads out in degrees Centigrade (°C). The upper readout is the actual heater block temperature. The
lower readout is the set point. The sample temperature set point is adjusted using the front panel
buttons, as explained in section 4.0, Controller Operation.
There is minimal maintenance required, beyond keeping the fan filter clean, and preventing spills of
liquid samples on the Vial Heater Module. Please see important safety notes in section 6 of this
manual. The Vial Heater Module operates at high temperatures. Spills, drips, and burns should be
avoided. Operators should follow all safety precautions for high temperature operation and sample
handling. Follow all precautions on the Material Safety Data Sheet (MSDS) for sample materials being
analyzed.
Maintenance is explained in section 5.0, Maintenance and Fuse Replacement. Please retain this
manual for future reference.
Note: The Vial Heater Module is designed for use with 3/8-inch fiber optic probes, operated in the
transmission mode.
