Specimen preparation facility

Chemical or mechanical extractions/preparations of study material, whether paleontological, archaeological or current.
The equipment allows in particular:
– the dissolution of carbonate rocks, using acids, to extract the fossil material
– the drying, washing and sieving of acid attack residues, sediments or substrates
– the release, using micro-hammers, fossil material included in rock blocks
– precision cutting and polishing for the production of thin-blades (to study microstructures)
– drying, grinding, sieving and precision weighing for the preparation of powder samples (geochemical analyzes).
