Reliable Food Analysis with Reproducible Sample Preparation

Aug 10, 2017· These ingredients would escape on warming the sample during grinding. Cold milling also preserves the original structures of proteins or vitamins. Grinding aids such as dry ice (solid CO 2; -78 °C) or liquid nitrogen LN 2 (-196 °C) are used to perform cryogenic grinding. These grinding aids embrittle the sample and make it break more easily.

Cyclone Mill Twister reproducible sample preparation

The sample is then thrown outwards by centrifugal acceleration and is pulverized between rotor and grinding ring. The 2-step grinding ensures particularly gentle but fast processing. The feed material only remains in the grinding chamber for a very short time. The integrated cyclone provides cooling of the sample and the grinding tools.
