Laser diffraction particle size analyzer PA-6000LDW

static light scatteringlaserfor the pharmaceutical industry

Overview
PA-6000LDW is a particle size analyzer combining dry and wet measurement modes with a measuring range of 0.02–2000 µm. The instrument supports powders, liquid suspensions, emulsions and magnetic materials and provides automated test sequences for reproducible results.

Working systems

• Dry system: analyzer host, auxiliary unit (vacuum, waste powder collection tank, air purification tank) and oil-free silent air compressor.
• Liquid (wet) system: integrated ultrasonic dispersion, mechanical agitation and circulation.
• Seamless switching: software-controlled changeover between dry and wet modes without manual hardware replacement to preserve test accuracy.

Applications

• Particle size distribution for dry powders and emulsions, including ferrites.
• Magnetic powders: NdFeB, hard and soft magnetic powders.
• Cement, cobalt powder, electronic materials, pesticides, pigments.
• Pharmaceuticals, ceramics, cosmetics.
• Paints, coatings and food ingredients.
• Calcium carbonate, talc, kaolin, alumina, rare earths.
• Catalysts, blowing agents, refractory materials, graphite.

Features

• Combined dry and wet measurement capability to handle materials not dispersible in water and to test a wide range of powders and emulsions.
• Computer-controlled mode switching and automated workflows for hands-off operation.
• Compact design with three main units: host, auxiliary unit and oil-free silent compressor; auxiliary unit includes filtration and dust collection for dry testing.
• Integrated wet cell with ultrasonic dispersion and circulation for effective sealing and low interference; automatic zeroing before measurement.
• Patented dry dispersion system generating particle rotation and collisions to achieve monodisperse states during measurement.
• Automated sampling and test sequence for consecutive measurements and result storage.
• Oil-free silent compressor: low noise, compact footprint, low power consumption and simplified maintenance.
