The CAP500 stage is designed to heat and cool capillaries from < -195°C up to 500°C
and can control the temperature of a ≤50mm section of high pressure quartz capillary.

The capillary is inserted through the body of the chamber and housed in a 1mm x 1mm
square channel in the heater cover. The block itself has been designed and engineered
to minimise the temperature gradient across the length of the capillary and can
provide accurate temperature readings to 0.1°C.

Capillaries which are loaded into the channel can be moved using the XY mechanism
to allow for observation across the length of the sample in the capillary. The CAP500
is suitable for capillaries with an outer diameter of ≤0.6mm. If you require different
size capillaries, please contact us as we may be able to provide a solution.

By using a high pressure pump and pressure gauge it is possible to pump samples
through the capillary at a specific pressure to investigate the rheology of the sample
with respect to temperature and pressure using brightfield, IR or Raman microscopy.

The CAP500 stage can also been used to study geological fluid inclusions created
in quartz capillaries.

If required, two capillaries can be tested simultaneously by selecting our Dual
Capillary CAP500 option.
