Title (EN) CENTRIFUGAL PISTON AND CENTRIFUGAL DEVICE COMPRISING SAME
(FR) PISTON CENTRIFUGE ET DISPOSITIF CENTRIFUGE L’INCLUANT
(KO) 원심분리용 피스톤 및 이를 포함하는 원심분리 장치
Abstract:
(EN) A centrifugal piston according to an embodiment comprises: a piston body defining a path which extends from the front of the piston to the rear of the piston, and through which substances at the front of the piston can move to the rear of the piston; and a valve disposed on the path and configured to selectively open or block the path, wherein, during centrifugation in which centrifugal force acts on the piston, the substances at the front of the piston are centrifuged while the valve is blocking the path, and, when an external force is applied to the piston while the centrifugal force does not act on the piston, the valve moves freely relative to the piston body, and when the valve opens the path, at least part of the substances at the front of the piston can move to the rear of the piston.
(FR) Un piston centrifuge selon un mode de réalisation comprend : un corps de piston définissant un trajet qui s'étend de l'avant du piston à l'arrière du piston, et à travers lequel des substances à l'avant du piston peuvent se déplacer vers l'arrière du piston ; et une soupape disposée sur le trajet et configurée pour ouvrir ou bloquer de manière sélective le trajet, où, pendant la centrifugation dans laquelle une force centrifuge agit sur le piston, les substances à l'avant du piston sont centrifugées tandis que la soupape bloque le trajet, et, lorsqu'une force externe est appliquée au piston tandis que la force centrifuge n'agit pas sur le piston, la soupape se déplace librement par rapport au corps de piston, et lorsque la soupape ouvre le trajet, au moins une partie des substances à l'avant du piston peut se déplacer vers l'arrière du piston.
(KO) 일 실시예에 따른 원심분리용 피스톤은 피스톤의 전방으로부터 피스톤의 후방으로 이어지며 피스톤의 전방에 있는 물질들이 피스톤의 후방으로 이동 가능한 통로가 규정된 피스톤 바디 및 상기 통로 상에 배치되며 상기 통로를 선택적으로 개방 또는 차단하도록 구성된 밸브를 포함하고, 피스톤에 원심력이 작용하는 원심분리 동안 상기 밸브가 상기 통로를 차단한 상태에서 상기 피스톤의 전방에 있는 물질들이 원심분리되고, 피스톤에 원심력이 작용하지 않는 동안 피스톤에 외력이 가해지면 상기 밸브가 상기 피스톤 바디에 대해 상대적으로 자유롭게 이동하며 상기 밸브가 상기 통로를 개방함에 따라 상기 피스톤의 전방에 있는 물질들 중 적어도 일부가 상기 피스톤의 후방으로 이동할 수 있다.
