## Abstract

Generally, an extraction system useful in separating an extract from a matrix using one or more extractants. Specifically, an extractor including one or more of: an extraction vessel having an extractor vessel internal surface which defines an extraction chamber which communicates between open extraction vessel first and second ends, a first piston configured to sealably engage the extractor vessel internal surface of the extraction vessel first end or a second piston adapted to sealably engage the extractor vessel internal surface of the extraction vessel second end.

## Claims

### Claim 1

A system, comprising:
a plurality of vessels each including:
an internal surface which defines a chamber which communicates between open extraction vessel first and second ends;
a first end closure adapted to sealably engage said internal surface of said vessel first end, said first end closure having a first end closure port;
a second closure adapted to sealably engage said internal surface of said vessel second end, said second end closure having a second end closure port; and
a valved conduit fluidically interconnecting said plurality of vessels, said valved conduit configured to allow pre-selection of each of said plurality of vessels as an extractor vessel or a separator vessel.
