Specimen Mounts, Holders & Consumables
for the Phenom Desktop SEM

Multi Holders for Smaller Diameter Pin Stubs

The 25mm diameter holder (#16142-25P) can accommodate up to four Small Diameter Pin Stubs, and the larger 32mm diameter (#16142-32P) holder can accommodate up to six. Ideal for desktop SEMs, where holder size can be limited, to enable loading more samples at once. Shown with and without Small Pins Stubs (Product #16142 Special Small Head Ø9.6mm, pin 8mm length x 3.2mm diameter), which are sold separately.

Material: machined aluminum with stainless steel allen set screws. Allen wrench included.

#16142-25P Dimensions are Ø25 x 10mm (0.98 x 0.39") without pin.
#16142-32P Dimensions are Ø32 x 10mm (1.26 x 0.39") without pin.

Standard Ø3.1mm (1/8") pin with a length of 9.5mm (3/8").

Mini Pin Stub

The Mini Pin Stub is ideal for small samples or parts which need to be examined individually. Takes less space with a head diameter of 6.5mm, small samples are easier to locate and it is a low cost alternative for the standard 12.7mm pin stub.

PELCO SEMClip™ Specimen Holders/Adapters for the Phenom SEM

PELCO Tabs™ Carbon Conductive Tabs, Double Coated

The simplicity of application and smooth, clean surfaces of PELCO Tabs™ Carbon Conductive Tabs are a significant improvement compared to many of the other common adhesives that have been used in SEM mounting. Both tab sides have a thick conductive adhesive (conductive inner tab is 35µm and the adhesive is 45µm on each side for a total thickness of 125µm [5 mils]) with a liner on both sides, a transparent liner and white liner respectively. They are ready for immediate use. The top protective liner does not have to be removed until the sample is ready to be mounted. This reduces possible contamination. Outgassing is negligible.

Many laboratories use these tabs for SEM in a large diversity of applications. Adhering of the tab to a mount or surface should be done slowly and carefully to maintain surface smoothness. Refrigeration will increase shelf life but a warm up period of one hour is then required before use.

The PELCO Tabs™ consist of a carbon fiber mat impregnated with a conductive adhesive. There is no internal carrier film. The conductive adhesive is a carbon filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924-1 which is solvent-free. Temperature maximum is 60°C (140°F). High purity carbon tabs may contain very small impurities of Al and Si; see EDX Spectra. This product may also be used for gunshot residue analysis.

3M™ Copper Conductive Tapes, Single Adhesive Surface

PELCO^® Isopropanol Based Graphite Paint

Conductive graphite paint, primarily designed for SEM sample preparation. The graphite flakes, with an average size of 1µm, are bonded by a cellulose resin with isopropanol as diluent. Good bonding properties on most materials. Graphite content is 20%. Ideal to mount samples on sample stubs or to make a conductive path to the sample surface. Let fully dry before using in the SEM. Maximum service temperature: 200° C. Use Graphite Paint Extender to dilute when needed.
