A light, positioned in the base of the pump head above the tank, is used to illuminate
both the beaker and the sample fluid within.
The sample pump and stirrer (described below) is attached to the bottom of the pump
head, whilst an ultrasonic transducer (not shown) within the sample flow path also helps
to disperse the sample.
Sample pump and stirrer
The sample pump and stirrer keep the sample in suspension and continually circulate the
sample and dispersant through the wet cell.
The stirrer, agitates the sample/dispersant mixture ensuring adequate dispersion prior to
a measurement. The central sample pump (in the middle of the assembly) circulates the
sample through the wet cell located in the measurement area of the optical bench.
The pump and stirrer speed is controlled by the Mastersizer software.
!
Warning!
Never run the pump/stirrer without the beaker in place.
