Abstract
A centrifuge labware includes a container and a removable, non-threaded lid. The container has a top opening which is at least about 90% of the cross-sectional area of the container.
Claims25
A centrifuge labware device comprising:
- (a) a container having very high axial strength, the container comprising a bottom wall and one or more substantially vertical sidewalls, the bottom wall and the one or more side walls cooperating to define an interior chamber having an interior chamber cross-sectional area, the container having a top opening with a first transverse axis and a second transverse axis substantially perpendicular to the first transverse axis, each transverse axis being at least about 9 cm in length, the top opening defining a top opening open area which is at least about 90% of the interior chamber cross-sectional area;
- (b) a removable non-threaded lid having an exterior surface, an interior surface and a very high axial strength, the lid being sized and dimensioned to cover the top opening so as to seal the interior chamber;
- and
- (c) a clip for securing the lid to the container.
