Working Principle
The reactor has a complex two-phase system that works like this: your substrate sticks to solid resin beads, and chemicals move through the liquid phase.
Phase 1: Coupling Reaction
The activated amino acids or building blocks combine with the substrate that is joined by resin. The low-shear agitation method keeps the resin solution even without wearing down the beads. Reaction rates are best when temperature is controlled through the jacketed tank.
Phase 2: Filtration & Washing
The built-in PTFE sandcore filter keeps the resin beads in place while draining liquid waste and extra chemicals. Using DMF or DCM for more than one cleaning run will get rid of all the dirt.
Phase 3: Deprotection
Protecting groups are split up in a managed way. The filter system gets rid of the deprotection chemicals well, getting the resin ready for the next coupling cycle.
Phase 4: Vacuum Operation
Integrated vacuum pipes make conditions that are dry, which are needed for processes that are sensitive to wetness. Nitrogen purging keeps the oxygen neutral, which stops oxidation.
The design of the system's dead-volume reduction keeps reagents from building up. The shape of the solid phase synthesis reactor vessels allows for 2x to 5x resin growth during the synthesis process.

Application Fields
Pharmaceutical API Manufacturing
Our reactor's binding efficiency of 99% or more helps you make peptide drugs. Under cGMP conditions, make GLP-1 agonists, insulin analogues, and medicinal peptides. The system can work with swollen resins with a high viscosity and keep strict temperature cycles for long synthesis campaigns.
Oligonucleotide Therapeutics
Make antisense oligonucleotides and siRNA in a completely dry environment. Gene-silencing treatments need to keep the sugar-phosphate backbone intact, which can be done quickly and automatically by solvent swaps.
Combinatorial Chemistry & Drug Discovery
Make collections of small molecules on polymer beads. The reactor keeps the resins in a regular suspension of different densities, which speeds up your hit recognition programs.
Chemical Intermediate Production
Make complicated organic intermediates by controlling the temperature, crystallizing the material, and filtering it all at the same time. Some of the good cases we've worked on are looking for antimicrobial peptides and making custom chemicals.
Bioengineering & New Materials
Create new nanomaterials and plastics that have been functionalized. Ultrasonic crystallization, distillation, and extraction are all built into the flexible system to provide complete process solutions.
Post-Consumer Recycling Purification
To meet FDA/EFSA food-contact safety guidelines, use scavenger resins to get rid of metal catalysts and other impurities from reaction mixes.
Quality Certification
Our manufacturing facility holds comprehensive international certifications ensuring you receive world-class equipment:
- CE Certification - European safety compliance
- ISO Quality Management - Consistent manufacturing standards
- UL Certification - Electrical safety verification
- SGS Inspection - Third-party quality validation
All products meet GMP/FDA standards in design, materials, and performance. Our quality assurance extends through every manufacturing stage, from material traceability to final Factory Acceptance Testing (FAT).
FAQ
Q: What's the difference between glass and stainless steel reactors?
A: Glass reactors provide complete visual monitoring of resin swelling and reaction dynamics, ideal for laboratory to pilot scale. Stainless steel offers superior durability for industrial-scale production with PTFE lining for chemical resistance.
Q: How do you prevent resin bead damage during agitation?
A: We use specialized low-shear helical or anchor impellers designed specifically to minimize mechanical stress. Alternatively, pneumatic nitrogen bubbling provides gentle agitation without physical contact.
Q: Can the reactor handle moisture-sensitive reactions?
A: Absolutely. Our integrated vacuum and nitrogen manifolds create and maintain anhydrous, oxygen-free conditions throughout your synthesis process.
Q: What filter pore size should I choose?
A: This depends on your resin bead size. G2 filters (40-80μm) suit most standard resins, while G3 filters (15-40μm) work for finer particles. We help you select the optimal specification.
Q: Do you provide installation and training?
A: Yes. We offer comprehensive technical support including installation guidance, operational training, and ongoing maintenance consultation throughout the equipment's lifetime.
Q: What's your customization lead time?
A: Standard product units ship within 5-7 days. Customized configurations typically require 30 business days from design approval to completion.
Q: How do you ensure the reactor meets my specific process requirements?
A: Our R&D team works directly with you to understand your synthesis protocols, then designs customized solutions including material selection, temperature ranges, automation levels, and integration with your existing systems.
