SK biotek Continuous Process Technology

A world leader in the development of custom cGMP Chemical Manufacturing of APIs and Intermediate by Continuous Flow Process.  With state-of-art manufacturing facilities, the capability to manufacture APIs and, Intermediates, plus the ability to scale up from kilos to multi-ton for global leading pharmaceutical companies.

SK biotek is the leading supplier of late-phase and commercial pharmaceutical materials using Continuous Flow Processing. Continuous Flow Processing has many advantages over traditional batch processes; it is not just greener, highly efficient, cost-effective, and regulatory support; but also has the capability to conduct low-temperature reactions, hazardous reactions (Azide/Hydrogen Peroxide, etc.), catalytic reactions, and other extreme chemistries not possible by batch processing.

Continuous Process Manufacturing Offers

  • Improvement in the degree of purity achieved and/or higher process yield
  • Avoids cryogenic process steps
  • Simplifies process scale-up
  • Achieves a higher process stability
  • Enables safe operation of reactions otherwise not possible in batch mode
  • Improves levels of process control through Quality by Design (QbD) approaches, combining improved process economics versus batch operations
