1 Introduction
The NIRS Vial Heater is operated in combination with the NIRS XDS Trans-
mission OptiProbe Analyzer.
The NIRS Vial Heater is used to pre-heat samples and control their temper-
ature during the data collection process. Controlled temperature can be
selected and maintained above room temperature and below 200 °C.
The NIRS Vial Heater consists of a temperature controller and a vial heat-
ing block.

2 Intended use
The NIRS Vial Heater is used for heating samples that are solid or very vis-
cous at room temperature. It is installed once and remains in place until a
calibration is necessary. If a calibration needs to be carried out, the NIRS
Vial Heater needs to be replaced by the calibration fixture.
Only use the provided disposable glass vials with a diameter of 8 mm
(6.7402.000). If you use different vials, the sample may not be heated
properly.
The NIRS Vial Heater 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,
incorrect wiring methods from those stated in this manual, or changes in
the system without written authorization and approval by Metrohm.

Protection against electrostatic charges
WARNING
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Do not fail to pull the power cord out of the power socket before you
set up or disconnect electrical plug connections at the rear of the
instrument.
3.3 Tubing and capillary connections
CAUTION
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing con-
nections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are manda-
tory.

5.1 Unpacking and inspecting the instrument
5.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately packed accessories. Keep this packaging, as only this ensures safe
transportation of the instrument.
5.1.2 Checks
Immediately after receipt, check whether the shipment has arrived com-
plete and without damage by comparing it with the delivery note.
5.2 Location
The NIRS Vial Heater should be placed in a work area with adequate room
for normal use, including loading and unloading of vials, and sufficient
room for fan circulation behind the instrument.
The system should be mounted on a bench or work location free from
vibration, direct sunlight, drafts and sudden changes in temperature or
humidity.
Leave room for an adequate bend radius of the fiber bundles. Fiber bun-
dles should not be kinked, and should not be bent in a radius of less than
15 cm (6”).

5.4 Connecting the NIRS Vial Heater to the power grid
The NIRS Vial Heater is supplied with power cords for both North Ameri-
can 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.
WARNING
Electric shock from electrical potential
Risk of injury by touching live components or through moisture on live
parts.
￭Never open the housing of the instrument while the power cord is
still connected.
￭Protect live parts (e.g. power supply unit, power cord, connection
sockets) against moisture.
￭Unplug the power plug immediately if you suspect that moisture has
gotten inside the instrument.
￭Only personnel who have been issued Metrohm qualifications may
perform service and repair work on electrical and electronic parts.
Connecting the power cord

6 Operation
If vials are loaded in the immediate vicinity of other equipment, take care
to avoid spills or drippage onto the Vial Heater. Provide a lab sink or other
facilities.
Vials must be filled prior to loading into the Vial Heater. Do not fill the vial
to the very top, or it may spill sample onto the heating block.
CAUTION
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 pre-
vent any spills or drips. If sample is spilled onto the Vial Heater, immedi-
ately turn power off, unplug the unit and let it cool to ambient temper-
ature. Once cool, the sample spill should be cleaned using appropriate
solvents and following all recommended safety precautions.

The controller display consists of 2 4-digit displays, one red and one
green. The current setpoint is the lower, green display. The current tem-
perature of the vial block is the top, red display. There are 4 buttons below
the display:
￭INDEX button – changes display mode
￭UP arrow – used to raise a setpoint
￭DOWN arrow – used to lower a setpoint
￭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) display the current temperature of the heating block. The green
segments (lower display) display the setpoint.
WARNING
Hot surfaces
The NIRS Vial Heater can reach temperatures of up to 250 °C during
operation. Touching it may cause burns, and nearby objects may ignite
or become damaged. Overheated samples may cause the vial to burst
and thus may injure persons. The heating block retains heat and may be
dangerously hot even when the Vial Heater is turned off or unplugged.
￭Do not touch the heating block.
￭Do not place objects in the immediate vicinity.
￭Wear protective gloves and protective glasses.
￭Remove plastic plugs from vials.
￭Always handle vials with an appropriate holding device.
Changing the setpoint
1Press the INDEX button.
The setpoint is displayed in red and SP1 is displayed in green.
2Select the desired temperature using the UP and DOWN arrows.
3When 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 setpoint will not be stored in the controller mem-
ory and the unit will not function properly.
4After the value has been set, press INDEX to return to the normal
operation mode.
