1. Water jacket connections (inlet/outlet ports)
2. Water jacket
The Heat exchanger consists of a 'jacket’ that surrounds the flow cell connection pipes.
Cooling/heating liquid is fed into this jacket to cool/heat the sample. The heat exchanger
can be used for two functions:
l To heat or cool the sample so that sample measurements can be performed at dif-
ferent temperatures.
l To eliminate temperature fluctuations after any sonication of the sample. This can
be important when working with some organic solvents, where temperature fluc-
tuations can cause a slight misalignment of the system. This misalignment is
caused by the changes in refractive index that are observed in solvents as the tem-
perature changes. This may cause the presence of large particles to be reported
and thus affect the particle size distribution measured by the Mastersizer system.
The water cooling would normally be provided by an external heater/chiller circulator unit.
This will be connected to the inlet â and outlet á ports on the front of the wet cell.
