Abstract
A closed system centrifuge tube is described and discussed herein that enables removal of waste and transfer and removal of samples via one or more ports of the centrifuge tube within the closed system, without exposing the sample to the outer environment. This may enable greater sample retention during sample processing and centrifugation of the sample.
