Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
120 words
An adapter for a container used for centrifugation of a sample, the container having a predetermined configuration on the interior surface thereof, the adapter having an external surface sized for receipt within the container, the lower end of the adapter being configured to conform to the configuration of the bottom of the container, the adapter further having a bore extending through a portion thereof, the bore having a first radially inner and a second radially outer surface connected by generally confronting first and second planar surfaces, the bore defining a volume adapted to receive a sample therein, the adapter being arranged to support the container from the interior surface thereof as the container is subjected to a centrifugal force field.
Claim 2
Dependent Claim
120 words
