Powder Disperser is a powerful software-controlled dispersion unit for dry
powders. Addressing a need in the field of particle characterization, the Clemex
Powder Disperser breaks agglomerates, without damaging the particles, so
that they might be easily observed and differentiated on glass slides for particle
size and shape analysis by optical Microscopy.
Powder dispersion is done in a few steps
Carefully place the powder in the nozzle chamber and position two
microscope glass slides in the holders. The computer interface allows the user
to select pre-defined particle dispersion templates. By selecting one of these
templates all the settings such as Starting Pressure, Dispersion Flow and Time
are already defined and allow users to start the dispersion process immediately.
If more control is needed, the user can step in and create his own particle
dispersion template and save it.
Ready in less than 4 minutes
Once a powder disperser run is initiated, it takes between 1 to 4
minutes for particle dispersion to complete, depending on the starting pressure.
The incoming air directed into the nozzle disperses particles into the dispersion
chamber and they fall back onto the microscope glass slide.
With its combination of hardware and software, the Clemex
Powder Disperser produces uniform and repeatable deposits of particles on
microscope slides. Furthermore, by using pre-defined templates the software
allows the user to get repeatable dispersion results.
Used in conjunction with the Clemex PSA300 workstation, it is an essential
part of any laboratory conducting particle size analysis. Analysis is made easy
and repeatable, and results can be validated since each particle is associated
to its corresponding measurement.
Other powder dispersers use compressed air which can often be contaminated
by oil or humidity. By using a vacuum system the Clemex
Powder Disperser introduces no contaminants into the air flow.
No broken particle
While most dispersers use fluidized beds or high-pressure aerosol,
Powder Disperser uses vacuum, insuring that no particle is damaged or modified
by the disperser?s environment. Specially designed nozzles combined with an
elongated particle dispersion chamber allow the particles to move freely minimizing
collisions with the top of the chamber therefore obtaining undamaged particles.
Dispersion chambers come in varying sizes in order to accommodate differences
in particle weights.
Powder Disperser system is mainly composed of a computer controlled vacuum
unit, a selection of powder dispersion nozzles (with different dispersion patterns),
a primary powder chamber, an elongated dispersion chamber and a twin-slide holder.
