ABSTRACT:
This centrifuge tube has the general shape of a conventional centrifuge tube or test tube. An external re-entrant groove is provided along an upper portion of the tube. An internal tube has an open end in the closed bottom of the centrifuge tube and is in fluid communication with a flexible external tube removably fittable into the re-entrant groove. This permits a sample to be centrifuged with the external tube in place in the groove and then the external tube can be bent down to withdraw heavy sediment from the bottom of the centrifuge tube.
