Peptide Synthesizers

Best in class automated peptide synthesizers

CSBio has been designing and manufacturing fully automated peptide synthesis instruments for over 25 years. Starting with the first automated peptide synthesizer on MS-DOS, CSBio has honed the systems to the flexible, reliable, and cost effective equipment they are today.

CSBio builds peptide synthesizers from research scale to commercial scale manufacturing, and utilizes all of these machines in-house. We are the only peptide synthesizer manufacturer that also manufacturers peptides at all scales.

Designed by chemists with the best engineers, we have the best in class peptide synthesizers which can be found in laboratories and pharmaceutical companies across the globe. CSBio sells more pilot scale and commercial scale peptide synthesizers than any manufacturer in the world.
