A1
Abstract:
Provided is a technology for reducing retention of a composite sample on a filter during sample purification.　A purification apparatus (1) for purifying an intended sample from a composite sample is equipped with: a container (50) for subjecting the composite sample to separation by means of a specific gravity difference using a heavy solution; a filter unit (90) for receiving a supernatant discharged from the container (50) to recover from the composite sample an intended sample having a smaller specific gravity than the heavy solution; and a discharge pipe (80) for introducing the supernatant discharged from the container to the filter unit (90). The filter unit (90) includes a filter (210) and a connector (26) that is attached to, so as to establish a connection between, the filter (210) and the discharge passage (80).
