Product Overview
When a sample needs to be reduced before panning, screening, or assay work, this simple tool gives better control than striking loose rock on a bench. The deep metal cup helps contain small pieces while the pestle breaks them down in stages.
Cast iron can add iron to a sample, so it is not the right choice for every lab method. Use it only for non-food material, clean it between samples, and control dust from silica-bearing rock.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Frequently Asked Questions
Q: Can I use this in the kitchen? A: No. It is intended for rock and mineral work, not food preparation.
Q: Will cast iron affect an assay sample? A: It can add iron contamination, so choose the preparation method that fits the test you plan to run.
Q: Does it turn rock into finished powder in one step? A: No. Work in small stages and screen or grind further if your test needs a finer sample.
