Description
Verder Scientific® Retsch® Mill, Ultra Centrifugal ZM 300, 120 V/50-60 Hz, 208240002
Features:
- Variable speed from 6,000 to 23,000 rpm
- Up to 20 % finer particles than with ZM 200
- Sample throughput increased up to 15 %
- Temperature monitoring
- Neutral-to-analysis sample preparation
- Very short grinding time
- Optional volume cassette for batch sizes up to 600 mL
- Efficient cooling of sample and grinding tools
- Improved sample discharge from the grinding chamber
- Particularly suitable for large volumes
- Sample bottles of 0.25 / 0.5 / 3 and 5 liters
- Extra cooling for temperature sensitive samples
- Better sample discharge for light sample materials
- Ideal for cryogenic grinding
- Measurement of the temperature of the cassette lid near the ring sieve
- The temperature is constantly shown in the mill’s display
- Continuous monitoring of the grinding process to detect deviations without fail
- Improved reproducibility for temperature sensitive samples
- Touch display with rotary knob for convenient parameter setting
- Cassette temperature and load shown during grinding
- Prevention of overloads by feeding the sample too quickly
- A push-fit system without screws
- Easy insertion and removal without tools
- Quick cleaning of rotors and ring sieves
- Smooth surfaces of the machine for easy cleaning
- The ideal solution for pulverizing samples that cannot be reduced to the required fineness at room temperature
- Liquid nitrogen or dry ice are used to embrittle the sample material
- Volatile components are perfectly preserved
- Cryogenic grinding is easy to perform with the ZM 300
- Recommended for plastics or very temperature-sensitive samples
