SEM Specimen Mounts & Stubs

SEM stubs hold the specimen and conduct charge away from it. SPI supplies the full range of standard geometries — cylindrical, pin-type, angled, threaded and pure carbon — along with planchets for EDS and WDS work and specialised holders.

SPI Supplies — SEM Specimen Mounts & Stubs

Overview

Every SEM specimen has to be mounted on something, and the choice of stub is not incidental: it sets how the specimen sits relative to the detectors, and it carries the charge away that would otherwise build up under the beam. Stage designs differ between manufacturers, hence the range of geometries — cylindrical stubs for JEOL-pattern stages, pin-type for others, angled stubs for viewing a surface at a fixed tilt, threaded stubs where the specimen must be held securely. Material matters for analytical work: pure carbon and pyrolytic graphite mounts contribute no spurious X-ray peaks, which is why EDS and WDS planchets are made from them or from beryllium. SPI also supplies specialised holders, work stations for specimen preparation, and forensic GSR sampler kits.

Models

  • SPI Supplies Cylindrical SEM Mounts — SEM Specimen Mounts & Stubs

    Cylindrical SEM Mounts

    Mounts are produced in three surface finishes and a range of diameters to match the specimen-stage clips used on different SEM makes and models.

  • SPI Supplies Pin-Type SEM Mounts — SEM Specimen Mounts & Stubs

    Pin-Type SEM Mounts

    Pin-type SEM mounts combine a flat specimen table with an integral cylindrical mounting pin that presses into a matching socket on the SEM specimen stage.

  • SPI Supplies Angled SEM Mounts (30°/45°) — SEM Specimen Mounts & Stubs

    Angled SEM Mounts (30°/45°)

    A pure-carbon 30° version and a threaded, 45°-angled male version are also available for specialized stage configurations.

  • SPI Supplies Threaded SEM Mounts — SEM Specimen Mounts & Stubs

    Threaded SEM Mounts

    Threaded mounts are also combined with the 45° angled geometry in one catalogue item for tilted, screw-mounted viewing.

  • SPI Supplies Pure Carbon SEM Mounts — SEM Specimen Mounts & Stubs

    Pure Carbon SEM Mounts

    SPI Supplies provides a published article statement describing the composition of these carbon mounts for users who need documentation for their analytical records.

  • SPI Supplies Specialty Holders & Mount Work Stations — SEM Specimen Mounts & Stubs

    Specialty Holders & Mount Work Stations

    Mount work stations provide a benchtop tray that holds a set number of round and pin-type mounts during handling and storage.

  • SPI Supplies Planchets (Beryllium, Diamond & Pyrolytic Graphite) — SEM Specimen Mounts & Stubs

    Planchets (Beryllium, Diamond & Pyrolytic Graphite)

    Beryllium, diamond and pyrolytic graphite planchets for EDS and WDS, adding no spurious peaks and made to be cleaned and reused.

  • SPI Supplies Forensic Gunshot Residue (GSR) Sampler Kits — SEM Specimen Mounts & Stubs

    Forensic Gunshot Residue (GSR) Sampler Kits

    Recovered residue amount depends on the firearm type, caliber, ammunition, and environmental conditions at the time of discharge.
