Warning: Finely pulverized sample always presents a respiratory hazard; a dust mask or other protection
should be worn when working with it.
Grinding jars should be cleaned after use. Methods include wiping with a damp paper towel, blowing out with an
air hose, rinsing with water or alcohol, etc. Most of these methods are not very effective, and blowing the dust
out of a jar with an air hose certainly causes a respiratory hazard. We recommend a 3-minute period of grinding
with a mixture of clean quartz stone, hot water, and soap or laboratory detergent. The residue is easily and
safely washed out of the jar, which then may be dried.
Technicians who are particularly concerned about cross-contamination may adopt the “grind and discard”
technique. After sample A has been ground and the grinding jar nominally cleaned, a portion of sample B is
ground and discarded, and the jar cleaned again. Now it should be possible to grind a portion of sample B
without contaminating it with sample A.
If a cleaned grinding jar will not be used immediately, store in a plastic bag. Hardened steel grinding jars should
always be dried and stored carefully, as they are prone to surface rusting.

Do not use the 8200 Planetary Mill with hazardous materials for which the unit was not designed. Be aware
of the hazards of the materials that are being used, particularly in the event of a spill. For instance, use of a
flammable liquid could create a fire hazard if a sample is spilled.
