Measuring device description

Particle size distribution: Sieve shaker

It rotates a sample on the sieve surface, adds the
vertical motion to the sample under the impact of
the tapping hammer, activates to shuffle particles
hitting the sieve surface, enhances the analysis
efficiency and performs screening.

Measuring device specifications

Model	Ro-Tap sieve shaker
Sample amount	50～100g
Particle size range	32μm～8000μm

PAGETOP

Particle size distribution: Laser diffraction type particle size
distribution measurement device

The particle diameter information scattered by the
irradiation of thre e la sers on the s ample is
detected at certain angles and the particle size
distribution is calculated.

Measuring device specifications

Model	MT3300EXⅡ
Sample amount	2～5g
Particle size range	0.02μm～1400μm

PAGETOP

Shape: Scanning electron microscope (SEM)

A microscope to observe an object by irradiating
an electron beam to the object and detecting
secondary electrons emitted from the object.
The structure of the sample’s surface can be finely
observed.

Measuring device specifications

Model	VE-9800
Sample amount	0.2～1g
Magnification ratio	15～20,000 times

PAGETOP

Powder characteristics: Powder tester

The powder characteristics evaluation device
proposed by Dr. Carr measures 7 kinds of
characteristic values and 3 kinds of supplementary
values as well and quantitatively evaluates
“fluidity” and “jettability” of the powder.

Measuring device specifications

Model	PT-S
Sample amount	1000mL
Measured items	Angle of repose, Compressibility, Angle of spatula, Cohesion, Angle of rupture, Dispersibility, Angle of difference, Loose bulk density, Packed bulk density, Uniformity

PAGETOP

Rheological properties: Cone-plate viscometer

An inner cylinder rotates at a desired angular
velocity. The viscosity is measured as the rotating
speed is varied at will.
The rheological properties of a non-Newtonian
fluid can be observed by measuring the viscosity
at different shear rates.

Measuring device specifications

Model	DV2THACP
Sample amount	20mL
Viscosity range	3～2,000,000mPa·s

PAGETOP

Wettability: Pulse NMR type device for
evaluating interface property

It measures the relaxation time of liquid molecules
adsorbed to particle surfaces and of molecules in
the bulk liquid, since the response to the change
of the magnetic field is different between the liquid
contacting or adsorbing to the particle surface
and the bulk liquid (H⁺ of the free state liquid not
in contact with the particle surface).

Measuring device specifications

Model	Acorn aria
Sample amount	10mL
Measured items	H^＋Relaxation time

PAGETOP

Water content (%): Halogen moisture meter

A halogen heating module heats the sample very
quickly, causing the water to evaporate.
The moisture meter continuously measures the
weight of the sample during the drying process and
displays the reduction of the water content.
When the drying process ends, the final results for
the water content and the dry matter content of
the sample are displayed.
