Essential SEM Consumables for JEOL SEMs

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.

PELCO^® Conductive Liquid Silver Paint

a reliable conductive ground path for SEM specimens
Air drying silver paint to make effective ground. Curable at room temperature and has high adhesion to any material. Surfaces do not have to be prepared prior to application and will adhere to such materials as polymer (phenolic) boards, ceramic, glass, metal, plastic and fiberglass. It should be mixed well with a spatula before using. RoHS compliant.

The container is offered in two sizes (15g and 30g) and is provided with an applicator brush. Silver flake grain size is an average of 80%, <1.0µm. Sheet resistance is 0.02 ohms per square @ 1 mil (0.001” = 0.025mm) thickness and is a function of the coating. Service temperature range is -40°C to 200°C.
Use #16021 gold/silver thinner/extender to dilute when needed.

PELCO Tabs™ Carbon Conductive Tabs, Double Coated

NEW Sizes - 15 and 32mm diameters now available

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.

Carbon Conductive Tapes, Double Coated

These carbon tapes are conductive and may be used conveniently for scanning electron microscopy or EDS applications.

This is the same material as the PELCO Tabs™, Carbon Conductive Tabs, but in tape form. The tape form allows for special application uses such as custom sizes, cut-outs and shapes. The purity of this tape is identical to the PELCO Tabs™; only very small impurities of Al and Si may be found.
