NMCF Sample Preparation and Hardness Testing

IMG_7205 (3).JPG

The NMCF houses a suite of sample preparation equipment for Metallography and Electron Microscopy as listed below. These systems are located in Jesser Hall. Sample preparation for SEM and TEM can also be done with our Helios FIB-SEM in Wilsdorf Hall. In addition, Rockwell, Vickers, and Knoop hardness testing equipment is available in Jesser Hall.

NMCF Metallographic and SEM Sample Preparation

  • Allied Hi-Tech Autopolisher

    Allied Hi-Tech Autopolisher

    The High-Tech Autopolisher is a programmable semi-automatic sample polisher and grinder for < 1 inch samples, located in Jesser Hall Room 129.

    Use the Autopolisher calendar for scheduling time on this instrument.

    Programmable parameters include: force mode, platen speed (40-600 RPM), comp/contra rotation (sample holder/platen), 0-120 minutes (15 second increments) cycle time, sample force (LbF or N), sample rotation speed, water rinse and force reduction (on/off, %).


  • Precision Cut-off Saw

    Precision Cut-off Saw

    Mager BR220 Precision Cut-Off Saw 8'' in Jesser Hall room 129.

    A Struers Labotom-5 manual cut-off saw is located in the basement of Jesser Hall.


  • Techcut4 Cut-off Saw

    Techcut4 Cut-off Saw

    Use the Allied Tech Techcut4 slow speed saw in Jesser Hall room 129 for cutting smaller samples.

    As for all cut-off saws, you need to bring your own blades.


  • Sample Lapping and Polishing Equipment

    Sample Lapping and Polishing Equipment

    Jesser Hall room 129 in MSB houses four polishing and lapping wheels, three 8 inch wheels, one 12 inch wheel, and one 8 inch auto/manual polisher.


  • Hitachi IM4000 Flat Milling System

    The Hitachi IM4000 system, located in Jesser Hall room 131, is used as the final preparation step to obtain flat samples for SEM and for hardness testing. The IM4000 also allows preparation of large cross sections of samples by using specimen masks.

  • Gatan Precision Etching and Polishing System (PECS)

    The Gatan 682 PECS, located in Jesser Hall room 131, allows for etching of surfaces and for sputter coating of different materials. For non-conductive samples to be studied in SEM a conductive layer can be deposited with the PECS.

  • Technics Sputter Coater

    Technics Sputter Coater

    The Technics coater in Jesser Hall room 131 allows sputter coating 30 nm of AuPd in 1 minute. We can coat a large sample up to 2" in diameter and up to 3/4" tall, or multiple SEM stubs at one time: 6x 1/2" stubs or 3x 1" stubs. Training videos for the Technics coater are available and should be reviewed prior to instrument training. Heat-sensitive samples can not be sputter coated with the Technics coater, instead, use the PECS system for sputter coating of heat-sensitive materials.


  • Cressington Sputter Coater

    Cressington Sputter Coater

    The Cressington sputter coater in Jesser Hall room 131 allows sputter coating 30 nm of AuPd or Pt in 1 minute. We can coat a large sample up to 2 1/2" in diameter and up to 3" tall, or multiple SEM stubs at one time: 12x 1/2" stubs or 5x 1" stubs. Heat-sensitive samples can be sputter coated at a large working distance using the manual mode of the Cressington sputter coater.

NMCF Sample Preparation for TEM

  • Allied High-Tech Multiprep System

    Precise sample preparation for optical, electron, and other microscopies

    Location: Jesser Hall 131

    The MultiPrep™ System enables precise semiautomatic sample preparation of a wide range of materials for microscopic (optical, SEM, FIB, TEM, AFM, etc.) evaluation. The instrument is capabile of parallel polishing, angle polishing, site-specific polishing or any combination in a reproducable manner, elminating user-derived inconsistencies. More information and training videos can be found in Sharepoint in the MultiPrep TEM folder.
