Pilot Scale-up

Pilot scale-up is a necessary step in the process of drug development to production, and an effective measure to reduce the risk of industrialization. Pilot scale-up is a small-scale production simulation test, which is based on small-scale experiments to study the feasible solution for industrialization. Scientists perform pilot scale-up to study the chemical reaction conditions of each step in a certain scale of device, solve the problems that cannot be found in the laboratory, and provide the design basis for industrialization production. In general, pilot scale-up is an important transition stage towards industrial production. BOC Sciences' pilot-scale drug product specialists are dedicated to the manufacture of liquid and lyophilized drug products in compliance with cGMP.

Tasks of the pilot scale-up

  • Check whether the process route provided by the laboratory has special requirements for process equipment, conditions, raw materials, etc. during pilot scale up and whether it is suitable for industrial production
  • Verify the reasonableness of the pilot process
  • Further evaluate and improve the process conditions, and obtain basic and stable data for each step of the reaction and unit operation
  • Selection of materials and types of equipment
  • Determine the requirements for heat and mass transfer for each reaction step The effect of dosing method and dosing rate on the reaction in exothermic reaction.
  • Determine the physical properties and chemical constants of raw materials and intermediates
  • Determine raw material costs, operating times and production cycles
  • Optimize the process flow of the entire synthesis route and the process protocols for each unit operation
