Products Sample Preparation Milling Equipment

Milling Equipment

KinTek provides modern mills and crushers to prepare samples for chemical and physical analytical methods such as AAS, NIR, ICP, and XRF. Proper sample homogenization to an appropriate level of analytical fineness is essential for reliable and accurate analysis.

To ensure reproducible sample preparation, KinTek's range of instruments allows for coarse, fine, and ultrafine size reduction of almost any material. The selection of grinding tools and accessories guarantees contamination-free and dependable sample preparation before laboratory analysis.


Laboratory mills are commonly used to prepare samples for analysis. They work by reducing the particle size (comminution) of a variety of materials, including wet, dry, hard, soft, elastic, brittle, and fibrous materials. These mills are used in a wide range of scientific fields, such as chemistry, pharmaceuticals, food analysis, materials testing, and life science.

There are various types of mills and grinders that are available for achieving coarse, mid-range, and fine results, all the way down to the nano range (<0.1 µm). Disk, hammer, mortar, planetary ball, rotor, and cutting mills are some of the most common types of mills used in laboratories.

Cryogenic mills, or freezer mills, are a specialized type of mill that freezes materials prior to reducing their particle size. This technique is useful for handling materials that are difficult to grind at room temperature, such as plastics or rubber. Freezing the material makes it more brittle, and therefore easier to grind to the desired particle size.
