ABSTRACT:
A device for the separation of a separable component from a liquid sample for use with an evacuated receptable includes a housing having an interior cavity and a separator membrane dividing the cavity into a first portion and a second portion. The separator membrane has a porosity selected for the desired separation thereacros. An inlet structure is provided for fluid communication between the first portion of the interior cavity and the source of the liquid sample. Communication structure is provided for allowing fluid communication between one of the portions of the cavity and the evacuated receptacle. A rigid receptacle is in fluid communication with the other of the portions of the cavity.
