EMD Millipore Introduces Compaction Technology to Improve Solubility and Facilitate Handling of Cell Culture Media Used in Biopharmaceutical Production
  • Dry compression process compacts powder media into granules
  • Compacted media minimize dust formation and increase flowability, improving handling and cleanliness
  • Accelerated solubility helps optimize media preparation

June 2, 2015, Billerica, MA — EMD Millipore, the Life Science division of Merck KGaA, Darmstadt, Germany, today introduced a new technology that compacts dry powder cell culture media into granules, accelerating solubility and improving flowability and handling. The compacted media are therefore more convenient to use, allowing biopharmaceutical manufacturers to further optimize their upstream processes.

The technology is water- and additive-free and applies compression force to EMD Millipore’s highly homogenous dry powder media, fixing that homogeneity in place and creating granules several millimeters in size. The process does not alter the media’s amino acid or vitamin composition, and leaves intact the physico-chemical parameters of dissolved media and feeds, preserving the media’s ability to support cell growth and productivity.

The resulting compacted media offers important advantages over traditional dry powder media. First, compaction significantly minimizes dust formation, improving media handling as well as cleanliness within the production area. In addition, the higher density of compacted media allows for faster dissolution, while improved product flowability facilitates the dosing and mixing processes and limits media caking.

“Biopharmaceutical manufacturers need cell culture media that are highly soluble, homogenous and convenient to handle,” said Andrew Bulpin, Executive Vice President of EMD Millipore, Process Solutions Business Area. “We developed our compaction technology to address the market need for dry powder media that reliably meet those requirements. Our unique process produces compacted media that are easier to handle and deliver the expected performance.”

EMD Millipore will use compaction technology to produce customized cell culture media formulations for customers’ specific process needs. The company also plans to use compaction technology to enhance its established portfolio of cell culture media products.
