How Can I Clean Mortar And Pestle In Laboratory?

It has seemed to be a challenge to clean the important piece of lab equipment, which is the mortar and pestle, which is used in the laboratory to grind specimens into granular sizes for whatever purpose deemed fit by the scientist.

It has been difficult because the mortar and pestle used in the lab are not cleaned like the regular ones at home.

Cleaning Mortar And Pestle In Laboratory

There is a guide on how to clean mortar and pestle in a laboratory.

Step 1:

I suggest you use a wire brush to remove the remaining particles from the mortar because there is a chance that they will react with water.

In the absence of a brush, you can use a thick towel to clean the mortar.

Step 2:

If you are certain that the debris is out, you can use hot soapy water to clean the surface of the mortar and pestle, but make sure the soap you are using doesn’t leave behind any scent.

Step 3:

After washing and rinsing the mortar and pestle, it is a good idea to air-dry them before moving on.

Don’t try to cut corners by using a dry towel, instead, look for a properly ventilated area in the lab and allow it to air-dry.

Step 4:

After the mortar and pestle are dried, rinse them with isopropyl alcohol.

The reason for this is that isopropyl alcohol contains deionized water as well as alcohol which aids in removing dust and dirt, as well as keeping the mortar and pestle in great shape for the next use.
