• The sample carrier is fixed to the top of the sam-
ple holder body by a fixing ring. Three different
versions of the sample carrier with different
depth are available: 0.8 mm deep, 0.4 mm deep
and a flat one. Depending on the sample to be
investigated sample carriers made of other
materials are available on request.
• The fixing ring is flexible and is put over the
edge of the sample carrier, allowing quick and
easy exchange of the prepared sample.
• The sample holder body contains a Pt10Rh-
Pt (type S) thermocouple which is used for sam-
ple temperature measurement and control. It is
located right underneath the sample position,
thus providing good correspondence between
the set temperature and the actual sample tem-
perature.
The thermocouple is connected to the connector
box by the cable for sample holder flange (see
also chapter 4.4.2 ).
The temperature shielding closes the opening of
the alumina insulation and provides a uniform
temperature distribution.
TIP: Please refer to chapter 7 for further informa-
tion.
The sample holder is inserted into the HTK 1200N
chamber with two guide pins and fastened by four
screws.
2.3 Connector Box
The connector box terminates the supply hose of
the HTK 1200N, which contains the control wires for
the temperature sensor, flange control and the sam-
ple spinner.

2.4 CCU 1000 Combined Control Unit
CCU 1000 is designed to control the sample holder
temperature in HTK 1200N and to guarantee safe
operation of the entire instrument. In order to reach
and maintain the desired sample holder tempera-
ture, CCU 1000 controls the heater inside the sam-
ple chamber.
CCU 1000 can be operated manually by means of
the push - buttons on the front panel, or it can be re-
mote-controlled via a serial RS 232 interface.
NOTICE
Risk of damage
Make sure that the contact surfaces between
sample carrier and top of the sample holder
body are free of dust and sample residues to
provide for a good thermal contact!
