title: A modification of the soxhlet apparatus for drug extraction from biological fluids.
abstract: The authors suggest a method to isolate drugs and toxic substances from biological fluids which appears to be of easier and better applicability than other systems, because it allows the extraction by means of a hot solvent, reduces manual operations and the waste of solvent, and shortens the time of execution for the researchers. A mathematical formula is proposed in order to evaluate the recovery-time curves of any drug shortly and with better accuracy.
