Pharmaceutical development and analytical laboratories

Modern pharmaceutical development and analytical laboratories are housed in the impressive Norcroft Building at the heart of the University campus. The laboratories provide an impressive range of enabling process equipment and analytical support instrumentation including:

  • Spray and Freeze drying
  • Micro and nano-processing
  • Solid dosage form processing including lab-scale granulation, tableting and coating
  • Structural and molecular analysis (PXRD, NMR, Raman, Mass Spectrometry)
  • Chromatographic (UPLC, HPLC, GLP, GC) and Thermal (TGA,DSC,DMA) analysis
  • Bulk powder and particle characterisation
  • Dissolution and Disintegration testing
  • Controlled stability testing cabinets (temperature/humidity/light)

Clean room facilities for melt extrusion

S‌cientists at the Centre for Pharmaceutical Engineering Science have access to clean room facilities (ISO8) for the provision of hot melt extrusion processing.

The clean room houses a PharmaLab (Thermo Scientific) 16mm twin screw extruder and is ideal for scale-up and optimisation studies as well as the manufacture of preclinical technical batches of pharmaceutical and healthcare related products.
