Use the vacuum tweezers or a pair of tweezers as
shown and place a W16G (16 x 0.17mm) (1) glass
cover slip (1) into the stainless steel ring.
Tap the edges lightly to ensure that it sits flat
against the surface of the block. If the cover slip
does not sit perfectly flat against the temperature
controlled surface the heat flow will be compro-
mised and the sample temperature will be signifi-
cantly different to the displayed temperature. The
Stainless Steel Ring is used to push the 16mm
cover slip around the surface of the block when
using the motorised XY manipulators.
Using a pipette or tweezers or spatula place the
sample on the 16mm cover slip. Ensure that the
sample is as small as possible and that it is as flat
as possible. Heat flow into or out of the sample is
affected by the amount of sample area in contact
with the temperature controlled cover slip.
Place a second 16mm cover slip on top of the
sample and gently tap the top with the back of the
vacuum tweezers to disperse powder samples to
ensure good thermal contact of irregularly shaped
samples and to create a flat surface for the micro-
scope lens to focus on.
Accurate temperatures can be obtained by keep-
ing the sample as small and flat as possible.
