This section contains an alphabetical list of companies that sell peptide synthesizers. One can also find automated or benchtop instrumentation for solid phase organic or combinatorial synthesis among these companies.

If you know of a company that should be added to this section, please email us.

1. Protein Technologies - Automated peptide synthesizers for research, custom, and large-scale peptide production. The Symphony Multiplex Peptide Synthesizer has 12 independent channels.  Users can start, stop, or pause any reaction vessel regardless of what the others are doing. The Prelude (6 parallel channels) handles special amino acid additions with zero prime volumes while the Tribute (2 independent channels, see below) features 101 unattended couplings, amino acid barcode scanning, a full-color chemical-resistant touchscreen, and cost-effective prepacked amino acid cartridges. Both come with E-mail Notification and Safe-Response features. The PS3 is PTI’s 3-channel introductory unit while the Sonata is for gram to near kilogram quantities of peptide.

2. AAPPTec - automated peptide synthesizers for research and industrial scale production.  Products include:  Apex 396 Multiple peptide synthesizer (1-96 peptides), Model 90 (.05 - 10mmol) for small to mid-scale, Model 400 for large scale (2L - 50L Reactors), Apogee for synthesis of single peptides and difficult sequences (.2mmol), Velocity for ultra-quick synthesis of up to 16 long or difficult peptides independently  using Fast-Fmoc and Fast-Boc, Titan 357 for split-and-combine chemistry and finally the Matrix 384 for Ultra-high throughput synthesis of up to 384 peptides simultaneously.
3. Activotec - the European distributor for AAPPTec peptide synthesizers. They also sell a line of manual synthesizers for organic solid phase or combinatorial chemistry purposes. They also sell the Activo-P11 automated peptide synthesizer
4. Advanced ChemTech - offering and servicing the Thuramed line of peptide synthesizers including: the Thuramed 1000 - a stainless steel, continuous flow single-product machine featuring a 5-L reactor and GMP capability; the Thuramed 100 - a fully-automated, bench-top, single product instrument featuring 16-amino acid positions with reactor sizes available from 25-mL to 500-mL; the Thuramed 300 - a fully automated, 3-reactor bench-top unit that can be used for peptide research or small to medium scale production featuring 50-amino acid positions
5. Applied Biosystems - makers of the ABI 433 peptide synthesizer for Fmoc and Boc solid phase synthesis. They also sell parts and accessories for their ABI and Pioneer (now discontinued) series of synthesizers.
6. Buchi - the Syncore Reactor is designed for parallel combinatorial chemistry and solid phase peptide synthesis. Heating, cooling, and vortexing can be adjusted to optimize reaction conditions.
7. CEM - supplier of microwave peptide synthesizers (manual and automated) for enabling synthesis of difficult and longer peptides. The automated Liberty system allows for the unattended synthesis of up to twelve different peptides with a scale range of 0.1 - 5.0mmol.
8. CS Bio - suppliers of research scale, bench top, process scale and manufacturing scale synthesizers, all fully validated for GMP usage - single reactors synthesizers from 40mL to 400L as well as multi-reactor synthesizers for small scale synthesis.
9. CSPS Pharmaceuticals - makers of MULTIBLOCK, a 48 manual, benchtop reactor for parallel synthesis
10. Innolabtec - benchtop instruments for parallel organic synthesis on the multi-milligram (InnoGram) and multi-gram (SemiGram) scale
11. Intavis - makers of three different peptide synthesizers (Autospot, MultiPep SPOT, and MultiPep). The AutoSpot is a an instrument for the synthesis of peptide arrays on membranes. Full automation of this process is possible with their MultiPep SPOT kit. The MultiPep is a "multi-platform" instrument and can synthesize peptides in plates, on membranes, or using columns.
12. J-KEM - makers of benchtop instrumentation for solution and solid phase organic synthesis
13. Multisyntech - makers of various instrumentation for completely automated (Syro I - Syro II) or semi-automated (SAP - SAM) peptide synthesis. In addition, they make an instrument suitable for automated, combinatorial solid phase synthesis (SAS).
14. Peptide Scientific - makers of the PSI 500, a fully automated preparative peptide synthesizer for GMP production
15. TechniKrom - maker of a process scale peptide synthesizer for industrial use
16. Scigene -the FlexChem peptide synthesis system can be used for performing parallel, manual synthesis of 96 or 48 peptides. The system is composed of a chemically resistant reactor / filtration block with independently removable sealing covers. Peripheral devices for loading solid supports; vacuum washing and recovery of products; and an optional benchtop rotator complete the system.
17. Thuramed - (a CreoSalus company) - their proprietary peptide synthesizers include the TETRAS asynchronous multiple peptide robotic synthesizer, the T1000 GMP production synthesizer, and the T100 bench top automatic synthesizer.
18. Tyler Research - Semi-Automatic Multiple Peptide Synthesizer (SAMPS)
