Important Safety Instructions:
1. Avoid contact with hydrofluoric acid.
2. Do not heat or place in the oven for drying.
3. If samples contain large pieces or lumps, crush them outside before grinding in the agate mortar.
4. Clean the mortar with water after use. For stubborn residue, wash with dilute hydrochloric acid, followed by water rinsing. If it remains unclean, grind a small amount of salt in the mortar, discard, and rinse. Alternatively, sea sand can be used for cleaning purposes.
5. Do not grind excessively hard objects or coarse particles in the agate mortar to prevent surface scratches.
6. Ensure the mortar is placed on a stable surface and remains vertical while grinding. Crush large solids outside the mortar to prevent damage. Handle explosive substances with caution, applying light crushing only. For corrosive materials, cover the mortar securely with a thick paper or plastic sheet, create an opening for the pestle, and then grind. Do not exceed 1/3 of the mortar's capacity with solids.
