Mainframe Material:
Available materials for grinding jars include hard steel, stainless steel, tungsten carbide, agate, sintered alumina, zirconia, and hard ceramics. Used for soil heavy metal analysis, four agate grinding jars are required. The pressure of the sealed agate grinding jars is set using a ruler. While rotating around the turntable axis, they also rotate in the opposite direction around their own axis, causing the samples in the jar to collide and friction, achieving the purpose of crushing, grinding, mixing, and dispersing the samples. Suitable for dry, wet, and vacuum grinding. Two or four grinding jars can be operated simultaneously.
