Mortar and Pestle

Features of the Laboratory Mortar and Pestle
Mortars and pestles are essential laboratory tools used for grinding and mixing solid substances. Their characteristics are as follows:

Materials: They are generally made of glazed porcelain for high durability and chemical resistance.

Mortar Design:
Shape: The mortar is a bowl-shaped container, spherical, or with a round bottom.
Interior: The interior of the mortar is unglazed or frosted for better grinding efficiency, providing a rough surface that aids in particle size reduction.
Pouring Spout: Equipped with a pouring spout to facilitate the transfer of ground substances.

Pestle Design:
Shape: The pestle is a heavy, blunt object, elongated cylindrical in shape, with a flat or rounded end for grinding.
Material: It is made of the same material as the mortar to ensure optimal compatibility and efficiency.

General Properties:
Chemical Resistance: They must be resistant to commonly used laboratory chemicals to prevent contamination and degradation.
Mechanical and Abrasion Resistance: The materials used must be hard and abrasion-resistant to withstand the grinding of solid substances.
Ease of Cleaning: The surfaces are easy to clean to prevent cross-contamination between experiments.
Applications: They are commonly used in laboratories, pharmaceutical, chemical, and food industries for sample preparation, powder mixing, and grinding solid substances into fine powders.
