In laboratories and pharmaceutical factories, mortar grinding is a common operation step. It can be used to grind granular or lumpy substances and grind them into fine powders. Mortar grinding is a simple but important step, and the correct use and precautions are very important for grinding results and operating safety.

the correct use of mortar grinding tools need to pay attention to the following points:

1. choose the right mortar: according to the need to grind the material and experimental requirements, choose the appropriate material and specifications of the mortar. There are usually porcelain mortar, borosilicate mortar and other different materials to choose from.

2. Clean the mortar: Before use, be sure to ensure that the mortar is clean and dry to avoid external impurities.

3. Pay attention to the grinding time: The grinding time of the mortar should not be too long, so as not to cause excessive grinding, affect the grinding effect or wear the mortar.

4. control the grinding speed: in the grinding process, the need to control the rotation speed of the mortar, so as not to affect the grinding effect too fast or too slow.

the use of mortar grinding tools also need to pay attention to some safety matters:

2. Avoid the use of aging mortar: Aging mortar is easy to break or produce impurities, need to be replaced regularly, to avoid interference with the experimental results.

3. Control the environment of mortar grinding: When grinding, keep the operating environment clean and tidy to avoid affecting the grinding effect of mortar.

mortar grinding is a common operation step in laboratories and pharmaceutical factories. The correct use method and precautions are very important to the grinding results and operation safety. I hope everyone can strictly follow the operating procedures and pay attention to the safety of operation when using mortar grinding tools.
