Metallography User Lab
The Empa metallography UserLab provides know-how and facilities for sample preparation using conventional metallographic methods (e.g. cutting, grinding and polishing). Access to the user lab is granted to all registered Empa employees, which have completed a general safety course and also received a personal instruction to the rules and safety aspects of the UserLab (see below). Please note that the UserLab Metallography is not a service center, i.e. we do not offer (routine) sample preparation tasks.
We provide the following facilities for metallographic sample preparation:
- Precision cutting machine (Buhler IsoMet4000)
- Low-speed saw (Buhler IsoMet)
- 40mm diameter hot mounting press (Buhler SimpliMet 1000)
- Various cold-mounting resins
- Grinding Machine (Buhler MetaServ 250)
- 3 semi-automatic polishing machines (Buhler PHOENIX 4000)
- Vibration polishing (Buhler Vibromet 2)
- Optical microscope with Camera (Zeiss Axiovert 100A / Canon DSLR)
The following consumables for sample preparation are provided by the UserLab in reasonable quantities:
- Standard cut-off wheels (note: diamond cut-off wheels are not provided by the UserLab)
- Hot- and cold-mounting resins (incl. clamps and other tools)
- Grinding Paper (FEPA 240-4000)
- A common stack of polishing cloths (note: individual sets are not financed by the UserLab)
- Commonly applied polishing suspensions and lubricants
- Raw-chemicals and equipment to prepare standard etching solutions
Off course, we can also support you with guidance and assistance regarding sample preparation and interpretation.
