Bioreclamation takes every precaution to provide only sterile products. Raw materials are collected using only sterile (i.e. cardiocentisis) or aseptic methods. Bioreclamation can also (at the request of the client) perform sterile filtration using vacuum driven, polyethersulfone (PES) membrane, low protein binding, 0.2u sterile filters. Filtration is performed under sterile conditions (i.e. sterile laminar flow), and all products are processed, aliquoted, and securely capped under this condition. Additional filtering options are available upon request.
