Adelaide Petrographic Laboratories was previously the thin section lab of Pontifex & Associates.

This lab has been providing sample preparation services for the Australian market for the past 35 years.

It was acquired by technician George Morgan in June 2013. George managed to retain the old Pontifex team, including the vastly experienced Peter Ruge. Adelaide Petrographic Laboratories operates out of the same premises as before.

We offer convenience, a quick turn-around, and guaranteed quality in the preparation of thin and polished thin sections.

APL specialises in assisting the mining, construction and quarrying industries. Research institutions, government agencies and students are also listed among our many clients.
