Specially Designed Specimen Holders For SEM:

Our specimen holders are designed to improve your productivity and allow you to view more than one sample at a time. You will save pump down time, keep your chamber cleaner and get more work done. All mounts are machined from solid aluminum and come with spring clips/or setscrews to hold your specimens securely. All mounts are made to fit onto your stage and are designed to fit through all standard specimen exchange ports, and have a center-threaded port to accept the Adapter Pins. Be sure to order the Adapter Pin that fits your instrument. For this reason, we offer three different types of pin adapters, which are threaded and ready to screw on to the base of the holders.

Adapter A: Overall measurement: 28mm long x 3.1mm diameter (step-up portion is 6.25mm L x 4.8mm diameter),

Adapter B: Overall measurement: 28mm long x 6mm diameter,

Adapter C: Overall measurement: 34.5mm long x 16mm diameter

All adapters have a threaded portion 5mm in length.

1) Universal SEM Sample Holder

This holder will hold almost any sample from 3mm to 29mm in diameter plus various odd shaped samples, which one of their dimensions is not greater than 29mm. The samples are easily inserted or removed from the holder. The holder is made from aluminum and is supplied with four removable sample arms so that it can hold very small samples as well, and it provides good electrical contact to the stage.

The AMRAY base is the standard base and it measures: 48mm x 42mm x 12mm Thick.

For all other makes and models you can choose an Adapter Pin to screw on to the AMRAY base holder.

2) Vertical Mount for Thin Samples; Flat Base

This holder is designed to hold thin samples vertically in the SEM or any microscope. It is 25mm in diameter and 10mm thick. Each of the two loader jaws can hold up to 3mm thick samples. The spring loader keeps thin samples vertical so that cross sections can be studied. This holder is very useful for cross sections of silicon wafers or multilayer capicators.

This holder can be adapted to any adapter pin listed above to accommodate your instrument.

3) Multi Pin Holder

The Multi Pin Holder is designed to save time. It accommodates 3 or 5 of ½" dia.(12.5mm) surface, 1/8" dia. (3.1 75910 Specimen

4) ISI DS 130 and 150 First Stage Sample Mounts

It is 10mm in diameter, 5mm high, copper sample holder to fit in the first stage of the ISI DS 130 and 150 SEM's. The inner cylinder is height adjustable so that you can adjust the sample to the correct working distance.

SEM Sample Holder Set

For your convenience we now carry a SEM Sample Holder Set to fill all of your needs. The set consists of one universal holder, one vertical mount holder for thin samples, one 3-pin and one 5-pin configuration holder with a key for the set screw all in a finely finished wood box.

Special Grids for SEM

Finder grids for SEM; a valuable tool for analytical studies. The grids are available in 10mm diameter and they can be placed directly on the stub surface and used to identify the area of interest in which the studies are performed.

SEM Finder Grid

These new SEM grids are designed to aid in the identification and localization of SEM specimens when placed on standard SEM stubs. 
The SEMF1 has several features that are incorporated for easier location of the specimen and identification of areas of special interest

  • Referring to the annular rim identifies north, south, east and west.
  • The four quadrant markers are tapered towards the center.
  • 100 Radial sectors are easily identified by reference to decimal numbers in the annular rim and alphabet letters in the four quadrants.
  • A matt surface on one side is for correct positioning – matt side up.

Type SEMF1

FIB Sample Holder

Fortress™ FIB Holder with CastleGuard™ Protection

Fortress™ FIB Holders are reusable holders that secure FIB sample that are held in a specific orientation without the use of adhesives, adhesive tabs, or conductive paints. Fortress™ FIB Holders can be used to position a thin, whole or cut TEM grid / disk in an orientation such that either in-situ or an ex-situ. FIB lift-out technique can be used to attach a FIB-prepared sample. Physical protection of the mounted sample on the grid is provided with the CastleGuard™ protection design. Up to 30 Fortress FIB Holders can be stored in a single SS200 Sample Saver™ storage container. Features:

  • Unique clamping mechanism secures sample without over tightening.
  • Standard 1/8" pin mount fits most FIBs and SEMs.
  • Peripheral support structure protects specimens during handling and transport.
  • Economical design offers user to prepare and store samples on the same holder.
  • Compatible with Sample Sver™ Stoage containers for secure stoage and transport in an inert environment.
