Laboratory disperser for high-viscosity products
Optimize your laboratory processes with precise mixing and dispersing of ultra high-viscosity materials, ensuring consistent formulations and streamlined development in compact batch operations.

Processes High-Viscosity Materials for Laboratory Applications
The KDV 31-3,0 and KDV 48-5,4 FU from Wilhelm Niemann GmbH & Co. are versatile laboratory dissolver and milling systems designed for high-viscosity materials. They specialize in mixing, dispersing, and evacuating processes, ideal for applications in paints, coatings, adhesives, and cosmetics. These systems feature an electro-mechanical lifting device and a comprehensive speed range of up to 12,000 rpm, accommodating batch sizes of 1 to 15 liters. With energy-saving frequency converters and optional vacuum designs, they ensure optimal energy efficiency and integration into various research and development settings. Available in robust stainless steel, they offer customizable options like double casing for thermal control and advanced PLC controls for automation. Meeting stringent ATEX standards, they promise both safety and reliability in high-demand laboratory environments.
