Pope Nutsche Filter-Dryers are known and used worldwide for final purification of pharmaceutical intermediates, high purity fine chemicals and other critical applications. Pope Reactors and Vessel Systems have been utilized for decades in the same industries. In many cases, Pope supplies reactors utilized for crystallization and a companion Nutsche for filtering, washing and drying the crystal slurries transferred from the reactor.

The advantages of pairing a reactor and Nutsche Filter-Dryer include:

  • Each vessel is optimally designed for performing these two different processes
  • Saves time by having both processes running simultaneously
  • Can be performed with no open handling of the raw material or slurry

Isolation is a critical operation, and often the final step in the entire manufacturing process. Pope Scientific’s Nutsches are preferred-proven for CBD crystalizing isolation to 99.9%, with less than 0.3%, to undetectable THC levels.
