SHAPE ANALYZER

Cilas shape and size analyzer

Cilas shape and size analyzer

For the last forty years, CILAS has maintained its position as the technological leader in the field of laser particle size and shape analysis. Our commitment in Research and Development provides a product with the highest level of performance and innovation.

Principle
CCD camera with inversed microscope for particle size and shape analysis, based upon statistical image data analysis for measurement of emulsions, suspensions and dry powders.

Sample preparation:
- Liquid mode: sedimentation of powders dispersed in carried liquid.
- Dry mode: deposition of the powder on a slide.


Fields of application
This device permits to:
- control the particle aggregation state,
- measure simultaneously the particle size and shape on the same sample.

Method of measurement
The particles are measured by the acquisition of the statistical numerical images associated with inverted microscope and computed by "Expert Shape" software.

Optical system
- Light source: halogen Bulb 6V-30W.
- Detection system: CCD detectors of camera.
- Inverted microscope with different magnifications.
- Four objective lenses: EPlan, Achromat, LWD (Long Work Distance): x4, x10, x20, x40 in standard. Other magnifications available, contact us.

Camera type
- Number of pixels: 768 x 576 – CCIR
- Pixel size: 8.6 µm (H) x 8.3 µm (V)
- Sensor size: 1/2“
- Voltage: 12V – DC

Well plate holder
Mechanical adapter for optical sample cell in wet mode and slide for dry powder.
With low position coaxial controls.

Size measurement
