                                                                 The dispersion bath incorporates a stirrer and an ultrasonic sonicator.   Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required
                                                                 A pump delivers  the dispersed suspension to the flow cell.            level of dilution, and a true image of the measurement object can be obtained.

                                                                 particles are circulated.
                                                                 It can be controlled from a PC.
