CEM Liberty Lite

Peptide Synthesis Made Fast & Efficient

Overview

The Liberty Lite™ Microwave Peptide Synthesizer is an entry level option for the globally recognized Liberty Blue™ technology. The Liberty Lite provides advantages over existing peptide synthesizers with it’s patented use of microwave irradiation during both the deprotection and coupling steps (15 minute cycle times), in situ temperature control, Flex-Add™ delivery system, and efficient solvent usage. Additionally, the system can be upgraded at any time to a complete Liberty Blue system.

Flex-Add Technology

Don’t be limited by fixed sample loops for reagent addition! CEM’s patented Flex-Add™ technology enables a wider range of addition volumes than any other synthesizer. This factory calibrated feature allows infinitely variable volume additions for all amino acid and activator deliveries, and requires no customer calibration after system installation.

In-Situ Fiber Optic Temperature Control

Fast heating requires fast and accurate temperature measurement to prevent thermal overshoot; in-situ temperature measurement provides the most responsive, reliable, and accurate feedback on reaction conditions. The fiber optic probe on the Liberty Lite provides this type of measurement capability and avoids the lag time associated with external IR or thermocouple controls and eliminates the need for routine calibration.

The Microwave Advantage

Microwave energy brings more to peptide synthesis than a rapid change in temperature. Combined with microwave transparent reaction vessels, your reaction, not the vessel, is heated with a uniform, single mode energy distribution. Rapid kinetic movement caused by microwave energy accelerates the reaction and reduces aggregation. The Discover® is the only microwave capable of applying microwave energy to both the deprotection and coupling steps of solid phase peptide synthesis.
