Microwave Peptide Synthesizer
Liberty PRIME 2.0
Overview
The Liberty PRIME™ 2.0 is the absolute best peptide synthesizer available in the world. The system features a unique one-pot deprotection and coupling process allowing for a remarkable 2 minute cycle time with only 8.5mL waste per cycle (at 0.1mmol). A key improvement in the 2.0 version of the Liberty PRIME is the ability to make cleaner and longer peptides with a new level of robustness than previously possible.
The Liberty PRIME 2.0 provides the ultimate flexibility for long, difficult, or complex peptides. Additionally, the system provides ultra-fast sequential synthesis workflow that can dramatically outperform traditional parallel peptide synthesizers. The Liberty PRIME 2.0 can be utilized in cGMP peptide production.

Solvent
Reduce SPPS chemical waste to unbelievable levels.
By using a patented process that reuses the coupling solution for the subsequent deprotection step, along with a system design that requires no internal washing the Liberty PRIME 2.0 reduces waste to unimaginable levels.
Up to 50% Less Waste
The Liberty PRIME 2.0 produces significantly less waste than the highly efficient Liberty Blue 2.0!

Advanced Reagent Delivery System
No calibration is needed.
All reagents are delivered either by pressure-based Flex-Add delivery system or precalibrated pumping system.
This means you can always be confident that the right amount of each reagent is delivered every time at volumes as low as 0.25mL. The Liberty PRIME 2.0 provides calibration-free reagent delivery that is ideal for GMP processes.

CarboMAX
The best coupling method for peptide synthesis.
- The fastest and most complete coupling
- Stabilizes acid sensitive linkages which are problematic for standard carbodiimide chemistry (phospho, glyco, hyper-acid linkages)
- Unmatched low-level of epimerization for all 20 amino acids due to faster activation (faster o-acylisourea formation)

High Throughput (HT) Loaders
High-throughput peptide synthesis made easy.
- Automated synthesis of 4, 12, or 24 peptides (individual 20mer’s can be completed every hour)
- The Liberty PRIME 2.0 paired with either the HT4, HT12, or HT24 outperforms conventional parallel systems
