Germanium (Ge) Granules, 99.999%-99.9999% Purity (Request Current Price)

ZHC LAB Germanium (Ge) 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. Pricing requires a current quote because high-purity metal costs vary with purity, package size, and material market conditions.

Key Features
