Our aseptic pre-filled syringe filling capabilities include filling solutions, emulsions, and suspensions for small molecules, steroids, and hormones. We’ve invested in specialized equipment to support microfluidization and high shear homogenization for complex formulations such as highly viscous, liposomal and nanoparticles.

Aseptic Syringe Filling

  • Syringe sizes – 1 mL, 1 mL long, 2.25 mL and 3 mL PFS
  • Fill volumes 0.1 mL to 3 mL 
  • Batch sizes up to 60,000 units
  • Ready to use in nests 
  • Rotary piston filling technology 
  • Liquid presentation
  • Terminal sterilization
