How It Is Used
A glass-fibre filter mat is laid over the perforated base and the crucible is set in a Gooch adapter on a filter flask. The precipitate is drawn onto the mat under vacuum, then the crucible goes into an oven or furnace for heating before it is weighed, which suits quantitative analysis and environmental testing.
