1 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.

2 General Specifications and Site Readiness
The Vial Heater Module should be placed in a
work area with adequate room for normal use,
including loading and unloading of vials, and
sufficient room for fan cooling behind the
module.
The fiber optic probes are attached on the left
and right sides of the module as shown in the
photo. Leave room for an adequate bend radius
of the fiber bundles. Fiber bundles should not be
kinked, and should not be bent in a radius of less
than 15 cm (6”).
The Metrohm NIRSystems instrument should also have adequate room for fan circulation. The system
should be mounted on a bench or work location free from vibration, direct sunlight, drafts, and
sudden changes in temperature or humidity.
The Vial Heater Module is supplied with AC power cords for both North American and international
use. The cord for international use is a “Harmonized International Power Cord” with color-coded,
stripped leads for use with approved local wiring connectors. A User Manual and a Spare Fuse
(T5A-250) are supplied.
If vials are loaded in the immediate vicinity of the equipment, care should be taken to avoid spills or
drippage onto the Vial Heater Module. A lab sink or other facilities should be provided.

6. Install the correct AC power cable into
the AC power block on the back of the
Vial Heater Module.
For locations outside North America, a
“Harmonized International Power Cord”
with color-coded, stripped leads is
supplied. Install the proper plug or
connector, following all local electrical
codes. Do not tin leads.
7. Plug the power cord into an AC outlet
that supplies the correct line voltage, as
set in step 5 above. This connection
provides correct earth grounding.
8. Turn on the AC power switch on the face
of the Vial Heater Module. The meter
display will illuminate to indicate
successful power-on.
For technical questions or more information on the Vial Heater Module, please contact your local
distributor, or contact the Metrohm Service.

The Controller display consists of two four-digit
4 Controller Operation
displays, one RED and one GREEN.
The current set point is the lower, green display.
The current temperature of the vial block is the
top, red display.
There are four buttons below the display:
• INDEX button -- changes display mode.
• UP arrow -- used to raise a set point.
• DOWN arrow -- used to lower a set
point.
• ENTER key -- confirms a setting change.
At power-on, all display segments will illuminate.
The display will quickly change to SELF-TEST.
Once self-test is complete, the red segments
(upper display) will display the current
temperature of the Vial Heater block. The green
segments (lower display) will display the set
point.
To change the set point:
1. Press the INDEX button. The set point will be displayed in red and SP1 will be displayed in green.
2. Select the desired temperature using the UP and DOWN arrows.
3. When the correct temperature is displayed, press ENTER to set the new value. This ENTER is
required to establish the correct set-point. If not performed, the set point will not be stored in the
controller memory, and the unit will not function properly.
4. After the value has been set, press INDEX to return to the normal operation mode. The actual
temperature will now be in RED and the desired temperature will be displayed in GREEN.
Once the displayed temperature of the Vial Heater module stabilizes, analyze the sample according to
your established analytical protocol.
WARNING!
The vial heater block may be operated at temperatures in excess of 200 °C. DO NOT touch
the block or severe burns could occur. Always handle vials with an appropriate holding
device. Follow established safety methods whenever handling hot objects.
The Vial Heater Block retains heat and may be dangerously hot even when module is
turned off or unplugged. Never touch the heater block without first measuring its
temperature.

Notice to Users:
The Vial Heater Module is designed to operate at high temperatures. Follow normal safety
procedures as required for high temperature operations. Metrohm NIRSystems is not responsible for
any misuse of the Vial Heater System, incorrect wiring methods from those stated in this manual or
changes in the system without written authorization and approval by Metrohm NIRSystems.
Vials must be filled prior to loading into the Vial Heater Module. Do not fill the vial to the very top, or
it may spill sample onto the heating block. If sample is spilled onto the heating block, it may be
baked on, which must be avoided.
Use caution when loading and unloading vials to prevent any spills or drips. If sample is spilled onto
the Vial Heater Module, immediately turn power off, unplug the unit, and let it cool to room
temperature.
This label appears on the cover and near where vials are inserted for analysis.
The surface temperature of the plate may reach 200 degrees Celsius.
This temperature may cause burns to unprotected flesh.
Always follow lab safety procedures when loading, unloading, or handling
vials.
Once cool, the sample spill should be cleaned using appropriate solvents, and following all
recommended safety precautions.
