<p>Disclosed is a centrifuge tube structure. The centrifuge tube structure comprises a tube body (2), a first blocking body (3), and a second blocking body (4). The tube body (2) has a first receiving trough (20), a second receiving trough (22), and a necking portion (21). The necking portion (21) is connected to the first receiving trough (20) and the second receiving trough (22). The first blocking body (3) is fixed on the first receiving trough (20), and defines a fixed volume compartment (200) with the first receiving trough (20) commonly. The second blocking body (4) moves along the second receiving trough (22), and defines a variable volume compartment (220) with the second receiving trough (22) commonly. The necking portion (21) defines a fluid communication path (210) to communicate the fixed volume compartment (200) with the variable volume compartment (220).</p> |
