With the blender I own, I was able to get perhaps 5-10% of the material into a fine powder, with the rest being relatively larger particles. There are many different food processors on the market, and I would like to know which specifications I should compare in order to determine if a food processor is capable of pulverizing plant matter to a ...

The Precellys® homogenizers from Bertin Health & Life Sciences use bead-beating technology to homogenize biological samples, such as human, animal or plant tissues, or to lyse micro-organisms. In this way, the biological samples are ground via multi-directional movement (3D bead-beating), the speed of which can reach up to 10,000 rotations per ...

Pressurized sample suspensions up to 35m1 are bled through a needle valve at a rate of about 1 ml/min. Because the process generates heat, the sample, piston, and cylinder are usually pre-cooled. Typical pressures used to disrupt yeast are 8,000 to 10,000 psi and several passes through the press may be required for high efficiency of disruption.

Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (-78 °C) or liquid nitrogen (-196 °C) that are capable of embrittling the sample by cooling and making it break more easily. An additional advantage is that the volatile components of the sample can be ...
