Automated Microwave Peptide Synthesizer
Liberty Blue HT12

High throughput peptide synthesis made easy.



The Liberty Blue HT12™ Automated Microwave Peptide Synthesizer is the gold standard for peptide synthesis. It features unmatched 4-minute cycle times along with a 90% solvent reduction based on High Efficiency Solid Phase Peptide synthesis (HE-SPPS) developed in 2013. The HT12 upgrade for Liberty Blue allows for the fast sequential synthesis of up to 12 peptides which offers significant advantages over traditional parallel peptide synthesizers. This system is utilized in hundreds of laboratories worldwide and provides unparalleled peptide quality based on its unique methodology and use of microwave energy. The Liberty Blue HT12 features the latest in engineering for fluidic deliveries, true internal temperature feedback control, and software control with 21 CFR Part 11 compliance.

CarboMAX coupling for peptide synthesis


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)
