Quanta-S Steam Sterilizable Freeze Dryers

We explore all design and budget considerations to help meet your  freeze drying requirements with the best possible equipment match.  Our knowledgeable engineers and consultants will help you explore all aspects of your freeze dryer requirement to help ensure you get the right system for your purpose. 

Some options for consideration include:

  • multiple skids for tight installation configurations,
  • redundant safety systems
  • clean-in-place (CIP)
  • isolation valves
  • automatic or hand secured door latches
  • round vs square chamber configuration
  • internal vs external condensers
  • stoppering or bulk
  • bellow seals
  • level loading doors
  • pass through design
  • a variety of documentation and testing

Freeze Drying in a Sterile Environment

Sterile production environments are most commonly found in bio-pharmaceutical and pharmaceutical organizations.   Millrock Technology, Inc supplies cGMP freeze dryers with steam sterilization and 21CFR part 11 for these demanding applications.  Our support lasts throughout the freeze dryer life cycle to help ensure that your project starts successfully and remains successful.  Our due diligence helps identify every consideration for a successful installation.
