The first mill ever used in a lab was the classic mortar and pestle. Time changes all, though, including lab equipment. While the mortar and pestle can still work for some applications, lab mills and grinding technology has greatly improved.
There are many different types of mills, all of which are best suited to different functions. The three following mill types are found in labs and pharmacies worldwide to serve many purposes.
Jaw crushers
To determine which kind of lab mill you need, you must first figure out what kind of materials you are grinding. Brittle, hard, and dry samples work best with mills that use pressure and friction to reduce the size of the particles you are working with. Jaw crushers meet this need. Mining operations and glass workshops frequently use jaw crusher mills in their work.
Mortar grinder lab mills
Jaw crushers do not work well with fibrous or elastic materials. Softer or liquid-like substances require mortar grinders. This style of grinder can be used with dry materials or a pasty ingredient. This type of grinder is commonly used for pharmaceutical applications.
Bead mills
Bead mills are most often used for organic materials, more specifically in tissue and cell cultures. For soft animal and plant tissues, a ceramic bead works best. Metal beads work well with harder tissues. Choose a glass bead mill when working with microorganisms.
