Manufacturer:

Eldex Laboratories have been designing and manufacturing metering pumps for over 30 years and have become synonomous with high quality and economic pricing.                                         

Eldex’s product ranges include -

Eldex ReciPro Optos Series HPLC Pumps, single piston with flow rates between 0.002 to 80 mL/min.  Flow rates are electronically controlled and an optional pulse damper is integrated to reduce flow fluctuations and provide for pressure limit control.

Eldex ReciPro Electronic Metering Pumps are based on a positive displacement, reciprocating piston design, which gives you precise flow control.   

- The Eldex HP Series has pumps with flow rates between 0.02 to 100 mL/min.  Flow rates are controlled via a precision micrometer.  The HP Series has been manufactured since 1978, assuring reliable, economical performance.                          

- The Eldex VS Series has pumps with flow rates between 3 to 144 mL/min.  Flow rates are set using a remote signal, or local potentiometer.  Precision micrometers can be added to expand the low flow rate range of the pumps.  VS Series pumps are ideal where remote control of flow rates is necessary, or, with the optional micrometer, when an expanded flow rate range is needed.

- The Eldex MicroPump with 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.               

Eldex Universal Fraction Collector  – The Universal Fraction Collector is versatile; permitting either time-based collection, in intervals of 1 to 999 seconds or minutes, or volume-based collection, from 1 to 999 drops per tube.  The unit accommodates five different spiral collection racks for collecting fractions of up to 75 mL.

Eldex HPLC Column Heater  -  The Column Heater improves the reproducibility of retention times in chromatography by providing a stable, temperature controlled environment, controlling temperatures from 5 deg C above ambient to 150 deg C.
The Eldex column heater will accommodate up to four standard 30cm columns up to 10mm O.D., plus guard columns.  A variety of column sizes can be used in the same heater, as the aluminum inserts are interchangeable.   Columns of up to 25mm O.D. can be used without inserts.
