PELTIER COOLED
STAGE:
The
Peltier Cooled Stage is used to maintain water on samples inside
the Quanta specimen chamber. It uses a thermoelectric module to alter
temperature, and this in conjunction with the appropiate chamber
pressure creates condensation on the sample. Thje primary moisture on
the sample or to keep the sample wet. The
K25X peltier cooling stage is installed in the microscope chamber to
give a control of substrate temperature.
The
Emitech K25X is a Peltier Driven Cooling Stage for SEM primarily VP
& ESEM. It allows the stage to be cooled to sub zero temperatures
for samples, which may be sensitive at ambient temperature, subject to
beam damage, or may be sublime at ambient temperatures.
The Cooling Stage is located on the existing SEM
Stage, and is designed to accept the standard range of stubs used with
the SEM.
The Cooling Stage on the SEM Stage has secondary
cooling via a liquid cooling circuit, through a ‘spare’ access port
on the SEM, to the external heat exchanger unit, which is fully vacuum,
isolated from the SEM chamber. This arrangement allows the majority of
the x,y,z and tilt features to be maintained to an effective operating
level.
The system is self-contained and employs a small
power supply and temperature control system, the unit is supplied from
standard supply socket.
The major parts of the system can be left in situ, and the Cooling Stage
is very easily removed when reverting to ‘normal’ use.
