We offer a wide selection of off the shelf high pressure precision metering pumps. We also customize our products to meet the needs of OEMs. Our ReciPro® line has models with flow rates from between 0.002 mL/min. to 144 mL/min. at pressures up to 6000 psi. The versatility of the ReciPro pumps makes them suitable for a wide range of applications, including column washing and backflushing, post-column reaction, reactant feed and other process applications.

Our MicroPro® pumps, based on a high pressure syringe design, are especially well suited for fluid delivery in the microliter per minute range, with applications in nano, capillary, and micro HPLC and LC-MS, as well as a variety of low flow uses.

The Eldex product range also includes a versatile fraction collector.

Eldex designed and manufactured the PicoTag™ Workstation for Waters. Now, we are able to offer an equivalent instrument called the Hydrolysis/Derivatization (H/D) WorkStation, as well as spare parts, accessories, and service for the PicoTag WorkStation and Vacuum Station.

In addition to our standard products, we manufacture a variety of specialized instruments and customize our standard products for other manufacturers.
