Graphite (C) Granules, 99.999% Purity

Graphite (C) Granules, 99.999% Purity

ZHC LAB Graphite (C) granules are high-purity evaporation source materials supplied for thin-film deposition research, PVD source loading, compound precursor studies, and laboratory materials development. The pellet and piece formats are convenient for weighing, loading, and small-batch experimental workflows where material identity, purity selection, and clean handling are important.

Key Features

High-Purity Elemental Source Material
Available purity options include 99.999% (5N) for research workflows that require controlled metal composition.

Pellet and Piece Formats
Available particle or piece sizes include 0.118 in-0.394 in (3-10 mm) granules/pieces. Package options include 1 kg, 100 g, 500 g depending on selected purity and size.

Clean Handling and Storage
Store sealed in a dry environment. Handle with clean gloves or tweezers and avoid contact with oils, dust, moisture, or other contaminants before use.
