Utilizing a state-of-the-art CCD detector, Mie theory, and unique design and data reduction features, the Saturn DigiSizer 5200 automatically measures particle sizes ranging from 0.1 to 1000 µm in just minutes. Optional features such as fully automated sampling and a low-volume sample-handling system make the unit ideal for a wide range of production, research, and quality control applications. In addition, new Confirm software addresses the many requirements specified by 21 CFR Part 11 encompassing validation, security, audit trails, reporting, and more.

pbs0802p26b.jpgImage Analysis System for Particle Characterization
The PSA300 includes two new critical components required for particle characterization. A unique algorithm improves accuracy when defining the length and shape of fibers. Older algorithms would define crossed fibers as an x-shaped particle, or it would break the fibers into four segments. Using this new algorithm, the unit separates crossing fibers as individual particles and assigns each one accurate size and shape parameters. A new automated sample disperser is a dry, free-flowing powder disperser that breaks agglomerates and assures a homogeneous spread of sample across the slide. While most dispersers use fluidized beds or high-pressure aerosol, this unit uses vacuum, ensuring that individual particles are not damaged and avoiding surrounding contamination.

pbs0802p26c.jpgLaser Particle-Size Analyzer
The 1180i laser particle-size analyzer features a built-in image analysis system that can measure and analyze particle shape as well as particle size. Aspect ratio, perimeter, area, and shape factor are some of the shape parameters that can be measured. The unit incorporates three lasers for ultrahigh resolution measurements and a wide measurement range. The system seamlessly integrates wet and dry dispersion in the same instrument without the need for hardware changes. Its short optical bench design ensures that the system is aligned at all times. All optical components are permanently fixed to a cast-iron base plate to ensure the most accurate particle size data.

pbs0802p26d.jpgParticle-Size Analyzer
The Gradex 3000 particle-size analyzer provides fully automatic sieve analysis for the gradation of aggregate material. The unit lowers costs by reducing the need for additional manpower and by reducing the amount of technician time required to perform testing. The machine analyzes up to 13 fractions utilizing a stack of standard, 12-in.-diam, half-height, round test sieves that can be easily changed to meet specific requirements. Suited for classifying materials such as sand, gravel, or crushed stone, the patented, PC-controlled unit provides analysis and a complete data printout ensuring consistent, reliable testing.

pbs0802p26e.jpgMobile Particle-Size Analyzer
With a refined user-friendly design, the Insitec Voyager is used for mobile particle-size analysis in the process environment. Smaller and lighter than the original Insitec Voyager, it can be operated at- or on-line, providing real-time analysis where and when required. The unit’s design has evolved in response to solicited customer feedback and increasing demand for consultancy services. Built for single-person operation, it is easily dismantled for transportation and can be assembled without the need for hand tools. The laser diffraction-based particle-size analyzer for dry streams with particles in the size range of 1 to 1000 µm is simple to connect to the process, easy to clean, and has more communications options.
