Metallographic sample prep CAMM

Jump to Struers LectroPol Electropolisher (Room/Cryo Temp)


Allied HighTech parallel polisher

The MultiPrep™ System provides 1 micron resolution for semi-automatic sample preparation of a wide range of materials for optical, SEM, OIM, TEM, FIB, and serial sectioning procedures. The MultiPrep™ System can facilitate parallel polishing, precise angle polishing, and site specific polishing for almost every microscopy application within CAMM. Touch-pad switches control all operations, with a numerical keypad to program platen speed, timer, oscillation and rotation settings. The system uses water as the standard coolant, however, automatic drip or dosing systems are available to apply abrasive suspensions and/or lubricants. The MultiPrep™ System provides reproducible sample preparation results by eliminating inconsistencies between users. 

The functionality and versatility of this tool are capable of extending to a number of different material systems, however, CAMM uses it mainly with nickel and titanium alloys.  Currently, the main uses of the tool are preparation of samples for serial sectioning with the NOVA FIB and conventional TEM grinding which require the samples to be polished to a thickness of 30-100 microns such that the surfaces remain parallel with one another.

Buehler auto polisher

The BuehlerVanguardTM 2000 autopolisher is a fully automated grinding/polishing system that can prepare metallographic samples for microstructural analysis from start to finish without continuous operator involvement.  Some of the autopolisher’s features include: an easy to use interface, dispensing system, multiple platens, and ultrasonic cleaner.  The autopolisher makes preparing many samples for use in the SEM or on the optical microscope simple and fast.  The autopolisher is most helpful during the large stereology “pushes” when many samples need to be prepared and analyzed in a short amount of time.

Ancillary Equipment:

The Simplimet 1000 Automatic Mounting Press, made by Buehler Inc., is an easy to use automatic mounting press.  Up to two 1.25” metallographic mounts can be prepared at a time in any desired tradition thermo set mounting medium.
