There is always a need to cut samples to pieces in a lab, so the mill is an essential piece of equipment in every laboratory.
It is necessary to understand that since various objects need Milling in a laboratory, there is a need to use the right grinder for best results.
Two major categories are milled in a laboratory:
Hard Samples.
These are samples that are complex and a little difficult to crush or cut into bits. For such materials, a strong mill is required to carry out the function of breaking them down into the desired form. Complex samples may be a hard knot to crack only when the right Laboratory grinder is not handy.
Mills with strength, friction, impacts are needed to crush dry and tough materials. Such materials could include Glass, dried wood, etc. For example, Jaw crushers can break down brittle objects into smaller pieces.
Soft Samples.
Soft samples are broken down easily with a mortar and pestle. They are usually supple or fibrous in texture. Mortar and pestle can be used for both natural and artificial samples.
How to Prepare Samples.
It is crucial to note that samples need to be in a particular state for them to be able to grind well. To get a piece to grind well, a preparation step is essential.
Plant materials or elastics that are not easy to break down could be exposed to dried ice or liquid nitrogen before milling. Some samples, if wet, should be dried before grinding to avoid them sticking to the mill, which can cause blockage. Other objects are frozen to make them easy for crushing. An example of such is nuclear acids.
It is essential to understand your sample, what you need them for and how you want them to look; this would help you get the right Laboratory mill.
