About Eldex

Eldex Corporation is a privately held company located in Napa, CA.  The company was founded in 1972 by Dr. Emmett Durrum, a distinguished scientist, innovative entrepreneur, and pioneer in the field of analytical chemistry.  The company focuses on developing precision instrumentation for scientists, chemists, and engineers.  From initial products including fraction collectors and HPLC column heaters, Eldex introduced the first in its line of high pressure metering pumps in 1978.  The company has trusted relationships with a blue-chip customer base and a carefully cultivated partnership network providing global distribution and support. 

High Pressure Metering Pumps

Eldex pumps have become widely accepted in applications such as solvent delivery, reactant feed, pilot plant, post-column reaction systems, and high performance liquid chromatography (HPLC). Our pumps are noted for their ability to reproducible deliver small volumes of fluid against high pressure (up to 6000psi). Over the years additional models of metering pumps were introduced, providing enhanced capabilities including remote control and metal-free fluid paths. Eldex places great importance on its reputation for quality and cost effectiveness.
