Product Overview
The Shimadzu 228-35601-92 (SPASSY) is a ultra-precision sapphire plunger assembly engineered for solvent delivery modules in Shimadzu High-Performance Liquid Chromatography (HPLC) systems, including the popular LC-10ADvp and LC-20AD/AB series.
Manufactured to microscopic concentricity and surface-finish tolerances, this monocrystalline sapphire rod plunger ensures ultra-smooth reciprocation against high-pressure seals. It delivers pulseless mobile phase delivery, consistent system pressure control, and minimized seal wear across demanding gradient and isocratic LC separations.
