<p>The present invention relates to a separatable test tube for use in a centrifugal separator, and more particularly, to a separatable test tube for use in a centrifugal separator that each stores a separation liquid separated primarily or does not need to separately transfer the separation liquid to another test tube in a second separation after a first separation. According to the present invention, the separatable test tube for use in a centrifugal separator includes: a first tube including a first coupling portion with a first thread formed an inner circumferential surface thereof and a second coupling portion which protrudes and extends from the first coupling portion and which has a second thread and a first groove formed along an outer circumferential surface thereof, and inside which an adjustment portion is fixed; a second tube including a first body part having a first space portion formed therein and a first packing fastener formed at one side thereof, and a third coupling portion which protrude and extend to the other side of the first body part, has a third thread and a second groove which engage in the first thread on an outer circumferential surface thereof, and has an adjustment groove opened and closed as the adjustment portion, which is formed therein; a third tube including a second body part having a second space portion formed therein and a second packing fastener formed at one side thereof and a fourth coupling portion which extends at the other side of the second body part and has a fourth thread which engages in the second thread formed on an inner circumferential surface thereof; a first watertight member coupled to the first groove; a second watertight member coupled to the second groove; a first packing coupled to the first packing fastener; and a second packing coupled to the second packing fastener.</p> |
