Using the Heat Shield
If your temperature controlled experiment
requires extra temperature stability, use the
supplied Heat Shield to cover the heater.
Use the Y
-
manipulator (1) to move the
Microscope Slide Holder to the middle of the
heating bock and use the X
-
manipulator (2) to
move the Microscope slide holder to the home
position (8mm from the edge).
The Heat Shield (3) is very precisely made with
the Microscope Slide Holder in this position, it
will ensure that the edges of the Heat Shield make
good thermal contact with the edge of the heating
element and a thermal oven around the sample is
created.
Place the Heat Shield over the microscope slide
so that it rests on the heating element. The
sample is now heated from all sides enabling a
very even temperature throughout the sample.
Heating rates may be slightly compromised due to
the extra thermal mass but sample temperature
accuracy will be improved.
Note: the Heat Shield is made from pure silver, a
soft metal. Please take extra care when handling
the heat shield and DO NOT bend it out of shape.
When not in use always store the Heat Shield in
the plastic casing provided for the stage.
To increase temperature stability even further,
place a (W16G) 16mm cover slip on the heat
shield to prevent heat escaping from the 5mm
aperture.
Note: This may slightly compromise your image
if high NA lenses are being used. Experiment to
see if this extra cover slip has a detrimental effect
on the image.
