Quality Control

The Quality Control Department at Waisman Biomanufacturing is staffed by highly qualified personnel who work to provide a comprehensive range of analytical testing services that ensures product quality and consistency during all stages of development and manufacturing. The QC group is also responsible for testing of in process samples generated during the process development phase of a project or where required during a clinical production run. In addition, our QC staff has the experience enabling them to develop, qualify, and validate product-specific assays tailored to meet client needs.

Quality Control Laboratory

The Waisman Quality Control Laboratory consists of a main lab space with two adjacent controlled rooms that are used for specialized cell culture and microbial assays.

QC Main Lab contains equipment for analysis of process development and final product samples.

  • forteBio BLItz system
  • BD Accuri C6 flow cytometer
  • Shimadzu 1601 UV-visible spectrophotometer
  • Multiple Agilent 1100 HPLC systems with diode array detector
  • BioTek ELX 808 Ultra Microplate Reader
  • Puffer Hubbard refrigerator and -20C freezer

QC Cell Culture Lab contains equipment for performing mammalian cell-based bioassays and is maintained at a positive pressure relative to surrounding areas to assure a clean environment for doing cell culture work.
