Cyclone mill for Nir analysis sample preparation
Ensure accurate NIR analysis by optimally preparing samples with efficient grinding and cooling, preserving their integrity and moisture content for reliable results.
Grinds and Coolly Separates Samples for NIR Analysis
The Cyclone Mill TWISTER from Retsch GmbH offers precise sample preparation specifically designed to meet the stringent requirements of near-infrared (NIR) analysis. Utilizing a combination of impact and friction, this rotor mill swiftly grinds, cools, and separates materials such as grains, feeds, and pharmaceuticals, preserving the essential qualities required for accurate analysis. With a robust 900 W motor and adjustable rotor speeds of up to 14,000 min⁻¹, it efficiently handles batch operations, accommodating a feed size of up to 10 mm and achieving a final fineness less than 250 µm. The integrated cyclone ensures samples remain cool, maintaining integrity and moisture content, while the easy-to-clean design eliminates cross-contamination risk and facilitates fast process cycles. Ideal for food processing and pharmaceutical industries, the TWISTER provides reliable results with minimal downtime, engineered to support both high-speed laboratory and pre-processing operations.
