Cryogenic Sample Crusher

The JFC series of cryogenic sample crushers consist of a cell, a tungsten carbide steel ball. The sample and the steel ball are placed inside the cell which is attached to a crush rod and the rod is attached to the main unit. The cell is immersed in liquid nitrogen to cool the sample and the steel ball. Then the crush rod is set in motion by reciprocating up and down and causes the steel ball inside the cell to pound the sample into a fine powder.
