Key Features

Grinding Performance: The ZM 300 achieves speeds up to 23,000 rpm, producing particles 20% finer than conventional mills.
Cyclone-Suction System: Ideal for light and heat-sensitive materials, offering efficient cooling and improved sample discharge.
Temperature Monitoring: Integrated sensor for continuous temperature display and monitoring, enhancing reproducibility for temperature-sensitive samples.
Cryogenic Grinding: Suitable for samples that require embrittlement using liquid nitrogen or dry ice, preserving volatile components.
Convenient Operation: Features a touch display with a rotary knob, easy cleaning, and a push-fit system without screws.

Performance Benefits

Variable speed from 6,000 to 23,000 rpm.
Increased sample throughput by up to 15%.
Short grinding times and neutral-to-analysis sample preparation.

Accessories and Adaptability

Sieves and Rotors: Various options available for different materials, including reinforced rim sieves and rotors with different tooth configurations.
Collecting Vessels: Options range from 900 ml to 4,500 ml, with a cyclone for larger volumes.
Vibratory Feeder DR 100: Ensures uniform grinding and is advantageous for large sample quantities.

Application Examples

Polymer POM: Achieves higher fineness at 23,000 rpm compared to 18,000 rpm.
Animal Feed: Sample throughput increased by 15% with a 0.5 mm ring sieve at higher speeds.
