ABSTRACT:
The present invention is directed to an automated peptide synthesizer equipped with recovery lines including an acyl component recovery line for recovering unreacted acyl components to allow the reuse of the acyl components, and a solvent recovery line for recovering and distilling a reaction solvent and passing it through a purification column to allow the reuse of the reaction solvent. Both recovery lines are installed on the flow pathway from one or more reaction chambers or columns to a waste liquid reservoir of the automated peptide synthesizer. By recovering expensive acyl components and solvents, running cost in peptide synthesis can be reduced to mitigate economic burden, and the amount of waste leading to environmental destruction can be reduced.
