In scaling-up, pilot stage plays a critical role. Besides variables such as raw materials and their behaviour during the process, engineering design, support and maintenance is extremely crucial. Scale-up calculations are dependent on the equipment specifications, such that it is in line with the R&D scale model as well as ready for manufacturing scale. Any error in such calculations could lead to serious failures in processing. ACG Pharma Technologies realizes this and offers Quest-FBE, a pilot-scale fluid bed processor that packs all the features of manufacturing scale equipment.
