ABSTRACT:
A system for preparing liquid biological substances, such as blood, blood components or cell suspensions for deep freezing which comprises atomizing a protective additive and dripping the biological substance into the stream of the atomized protective substance which is then collected in a receptacle and deep frozen. The system provides an effective way of intimately mixing the protective substance with the biological material to ensure a homogeneous distribution of the protective agent therein.
