The SDF550 Laboratory Disperser is a precision benchtop high-shear dissolver and wet grinding mill engineered for quality inspection, color matching, and recipe development across paints, coatings, printing inks, cosmetics, adhesives, and specialty chemicals. Built to provide seamless scalability to commercial industrial high-speed dispersers (PDM series) and horizontal bead mills, the SDF550 delivers repeatable shear kinetics in trial batches from 200 ml up to 10 Liters.
Equipped with an advanced permanent magnet brushless DC motor (PMDC), the machine operates without carbon brush wear or sparking hazards. Its intuitive PLD digital control console and 4-digit LED display allow laboratory technicians to maintain exact tip speeds, examine rheological stability, and switch seamlessly between saw-tooth Cowles dispersing and bead milling configurations.
Driven by a modern 0.55 kW permanent magnet DC motor with zero carbon brush consumption. Eliminates carbon dust contamination in sensitive white trial batches, generates high starting torque, and produces low operating noise (<60 dB) with no electrical spark interference.
Precision PLD control technology allows linear, stepless speed adjustment. A vibrant 4-digit LED digital display provides real-time speed monitoring, enabling laboratory formulators to replicate exact shear tip speeds across varying batch volumes.
Comes standard with interchangeable saw-tooth Cowles dispersing discs (Ø50 mm, Ø60 mm) and specialized sand milling discs (Ø45 mm, Ø60 mm). When paired with grinding media in a trial cup, it operates as a high-efficiency lab sand mill. For sealed R&D wet milling, explore our PZL laboratory horizontal bead mill.
Tool-free quick-clamping mechanism and mirror-polished stainless steel shaft make washdowns effortless. Researchers can perform rapid multi-color trial changeovers with minimal solvent waste. For immersion trials, compare with our PZM-L laboratory basket mill.
