According to the (a) lessor diameter and (b) eccentric mounting, access may be had by hypodermic syringe or thin pipette down the side of the first container to separated liquid present at the bottom of the second container. Normally a large number of arrayed sample containers each positioned within a collection container are (i) loaded with samples, typically by use of a pipette, and then (ii) centrifuged in parallel while held in a rack, the (iii) separated liquid being withdrawn by syringe or pipette without necessity of separating the sample and collection containers, and (iv) the used containers discarded.
