It offsets on the inside of the centrifuge tube；The side of lower layer's foam and/or the mutual direction of the upper foam is equipped with groove, described recessed
The space that slot is formed is corresponding with the shape of the vial, and the vial is set in the groove.
In the utility model one or more embodiment, the upper foam accounts for the half of the centrifugation pipe volume
To 2/3rds.
In the utility model one or more embodiment, the lower part of the centrifuge tube is taper or arc, the lower layer
The shape of foam lower part is corresponding with the lower shape of the centrifuge tube.
In the utility model one or more embodiment, the centrifuge tube is equipped with upper cover.
In the utility model one or more embodiment, the centrifuge tube is 50mL plastic centrifuge tubes.
In the utility model one or more embodiment, the vial is 20mL head space vials.
The beneficial effects of the utility model：
The utility model provides a kind of plasticiser extracting solution centrifugal device, and internal layer is head space vial, outer layer be plastics from
Heart pipe, between internal layer and outer layer be equipped with upper foam and lower layer's foam, in use, n-hexane in head space vial to sample into
Row extracting operation is placed into the space of the groove formation of upper foam and/or lower layer's foam and is fixed, then centrifuged.?
In the case of ensureing that glass container is intact, the utility model solves extracting solution and the difficult layering of provision room emulsification and extracting solution are muddy
The problem of, pollution problem of the experiment container to experimental result is also avoided, the accuracy of experimental result is improved.
