Liquid Chromatography Systems

The EcoPrime from LEWA is a complete chromatography system from a single source, combining LEWA intellidrive technology with LEWA diaphragm metering pump expertise.

Flow rates of 0.030 l/min to 60 l/min.

The widest dynamic adjustment range is 1:150.

LEWA EcoPrime® Chromatography System

Pioneering technologies combined for demanding applications.

The combination of Lewa's world leading LEWA diaphragm metering pump in hygienic design with their Intellidrive technology forms the basis for one of the world's most advanced chromatography systems.

The LEWA EcoPrime can be used as both a buffer dilution system and as a stand-alone chromatography system. With low holdup volumes and flexible adaptation to various process tasks, the EcoPrime is a chromatography system that gives your production process maximum performance and simple reproducibility.

Good reasons to choose a LEWA EcoPrime® chromatography system

The LEWA EcoPrime chromatography system consists of a mechatronic drive unit, hygienic diaphragm metering pumps, and all additional applications.


Complete system with tried-and-tested LEWA pumps

From selecting pumps through to system components, LEWA pieces together your specific chromatography process solution in its entirety. The heart of the LEWA EcoPrime system is the pump technology with EHEDG-compliant pump heads in hygienic design, multilayer PTFE diaphragm, and diaphragm monitoring system. The pump heads are separated from the gear unit compartment, which prevents the contamination of the liquid.


Unmatched accuracy

What makes the LEWA EcoPrime really stand out is its unmatched accuracy at a flow tolerance of 0.5%. The fast flow stabilization enables rapid column equalization. Chromatographies are easy to reproduce thanks to constant back pressure.


State-of-the-art design that complies with pharmaceutical requirements

State-of-the-art measuring technology and flexibility means that the EcoPrime chromatography system meets all pharmaceutical requirements. It can be fully drained and is both CIP and SIP-capable. The holdup volume has been reduced with an advanced bubble trap.


System flow independent of inlet pressure

The inlet pressure in the tank or in the discharge line has no impact on the system flow.

High dynamic range

The high dynamic range enables the use of many different chromatography columns.

Long service life

Thanks to the almost pulsation-free flow rates, the service life of the column medium is extremely high.

Linear gradient

The linear gradient of the chromatography system can be set between 1 and 99%.

Excellent compatibility

Our system can be freely combined with all SCADA systems.

Compliance with international standards

GMP compliance from DQ, IQ/OQ through to SAT and final acceptance, audit trail for compliance with specifications pursuant to CFR 21, part 11, and user and intervention traceability.
