This inexpensive and simple laboratory die utilises the optically polished face surface of the two bolts as integrated pressure pellets.
One bolt is screwed into the body and the sample/KBr mixture is then filled into the body using a funnel or spatula. The second bolt is then screwed in. Attach a vacuum pump to the connector and, using spanners, tighten the two bolts until the sample has been formed into a disc for spectroscopic analysis. A laboratory press is not required.
