laser particle size analyzer LLPA-A10


Laser particle size analyzer LLPA-A10 is a fully automatic cost effective and efficient particle size analyzer capable of measuring suspension, emulsion and powders. It uses laser diffraction measurement principle for measuring over the 0.1 μm to 300 μm particle size range for wet dispersion and is also well equipped with highly sensitive ring photoelectric detector which improves test accuracy.

  • Comprehensive laser diffraction particle size measurement principle
  • Highly sensitive ring photoelectric detector which improves the test accuracy
  • Fully automatic software control
  • Capable of measuring suspensions, emulsions and powders
  • Automatic optical bench alignment
  • Built in dispersing unit consisting carefully aligned stirring set up, ultrasonic dispersing unit and the sample circulating pipes
  • Built-in design effectively prevents the inhomogeneous dispersion and sedimentation of big particles
  • Optional small capacity sample chamber which helps with measuring expensive/precious samples or samples difficult to be dispersed within the medium
  • Analysis software uses an unique unconstrained data fitting technique developed to obtain data of unknown size distribution
  • Manual and automatic mode of operation makes it user friendly
It finds wide application in cement industry, ceramics, environmental and soil applications, pharmaceutical industry. It is also used for measuring the particle size of food stuff as well as paints, pigments, coating, ink, toners, fillers etc.
