Alumina mortar and pestle is a common tool used in laboratories for grinding, mixing, and crushing solid substances. 
It consists of two parts:
Alumina mortar: A mortar is a bowl-shaped container usually made of high-purity alumina ceramic material. It has a smooth inner surface and a sturdy structure that can grind and mix materials effectively.
Pestle: A pestle is a rod-shaped tool that fits inside the mortar. It is used to crush, grind, or mix substances by applying pressure and friction to the inner surface of the mortar.
The front end of this alumina mortar adopts an open design, which makes it easy to transfer the powder after grinding. It is easy to clean, just rinse it with clean water before and after use.
Mortar Capacity (ml): 15ml, 30ml, 80ml, 120ml, etc.
Available in various sizes.
