The Microtrac S3500 is a industry-preferred Laser Diffraction (LD) analyzer, ideally suited for various particle characterization tasks. It is the first particle size analyzer that uses three precisely placed red laser diodes to accurately characterize particles like never before.
The patented Tri-Laser System provides accurate, reliable and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles. The S3500 measures particle size from 0.02 to 2,800 µm.

Product Advantages
Rugged surgical steel construction protects the instrument from corrosion
High compatibility with samples allows for organizations to have multiple purposes for the instrument
Ultrasonic power and duration is programmable
Dry Powder Dispersion Device Combined with Laser Diffraction Systems
TURBOTRAC
TURBOTRAC’s primary function is to deliver a properly dispersed sample to the measuring cell in the Microtrac optical bench allowing for consistent and repeatable particle size analysis of dry powders.
Features
Flexibility of compressed air and flow conditions settings
Small sample volumes
Rapid measurements
Automatic sampling
Repeatability
Data consistency
Product Advantages
Allows the user to achieve dispersion usually associated with fluid dispersal systems for highly agglomerated materials such as alumina. Dispersion conditions can be altered for the measurement of the most fragile crystals
Sample volumes can be as small as 0.1 ml. Ideal for applications when sample is expensive to produce/ produced in small volumes
Measurement time is typically 10 seconds with the Turbotrac Autoscan – even shorter using the Microtrac One-Shot accessory for very small sample volumes
Microtrac FLEX software facilitates easy programming of measurement cycles. Simply place the sample in the sample tray, enter identifiers and press RUN. Data is saved
Data is comparable to fluid dispersions in most cases
Consistent control of aspiration settings deliver excellent sample-to-sample and bench-to-bench repeatability
Circulation device made for small, high value materials and for dispersing materials in expensive fluids
