A method of separating fluid into two or more separable fractions. One container section (2) and the adjacent portion of the other container section are made of solid material, and the two container sections are screwed together. The container sections (1 and 2) have their respective chambers (29 and 30) for receiving their respective fluid ingredients, and these chambers are interconnected through a connecting channel (31) through the abutting portions, at which the container sections (1 and 2) are screwed together. A valve seat (21, 27) is shaped at each end of the connecting channel (31) for each valve member (22, 16) for a sealing closing of the chambers (29, 30) in the separated state of the container sections (1, 2). The valve members (22, 16) have mutually abutting projections (23, 12) ensuring a distance between the valve members (22, 16) exceeding the distance between the associated valve seats (27, 21) in the coupled state of the container sections (1, 2) , but being smaller than the distance between the associated valve seats (27, 21) in a position during a separating movement of the container sections (1, 2). Furthermore, retaining means (15, 16) are provided for ensuring that the valve members (22, 16) do not engage the valve seats (27, 21) in the coupled state of the container sections (1, 2).

[ I claim:] [1.] A method of separating fluid into two or more separable fractions, comprising the steps of:providing a container having at least a first and a second chamber which are separably joined by cooperating connectors proximate an opening in each of said chambers and in fluid communication

[ I claim:] [1.] A method of separating fluid into two or more separable fractions, comprising the steps of:providing a container having at least a first and a second chamber which are separably joined by cooperating connectors proximate an opening in each of said chambers and in fluid communication when joined;admitting a fluid into at least one of said first and second chambers;providing a closure for selectively sealing the opening in at least one of said first and second chambers;causing said closure to be open to permit fluid communication between said first and second chambers through a channel when said first and second chambers are joined and centrifuged;centrifuging the container and fluid to cause a first separable fraction to accumulate preferentially in one of said first and second chambers;accumulating a substantial portion of the remaining separable fractions in the other of said first and second chambers;selectively sealing the opening in at least one of said first and second chambers after said centrifugation but before said chambers are separated by causing said closure to seat and close said channel when said cooperating connectors are moved apart; andthereafter separating said chambers; wherein said step of selectively sealing the opening in at least one of said chambers is accomplished automatically as the chambers are being separated but before the interior of the sealed chamber is exposed to an external environment.
