    • A method for carrying out a multi-step reaction, said method comprising 1) adding one or more first reagents to a reaction vessel, said reaction vessel comprising an upper chamber capable of holding reagents, which is open to a lower chamber to which reagent flow is restricted, 2) subjecting said reaction vessel to a centrifugal force so as to drive the said one or more first reagents into the lower chamber; 3) adding a further reagent to the first chamber and closing said chamber; 4) subjecting at least one of the lower chamber or the upper chamber to conditions which cause said one or more first reagents or said further reagent to take part in a first reaction or reach a desired reaction condition; 5) subjecting said reaction vessel to a centrifugal force so as to drive the said further reagent into the lower chamber and allowing it to interact with the contents of the lower chamber; wherein at least steps (2) to (5) are carried out automatically . This method allows multiple steps to be carried out in vessels without opening the vessel. It is particularly suitable for use in connection with PCR reactions.
    • 一种进行多步反应的方法,所述方法包括:1)向反应容器中加入一种或多种第一试剂,所述反应容器包括能容纳试剂的上室,所述反应容器向下室开放,试剂流 2)对所述反应容器进行离心力,以驱动所述一种或多种第一试剂进入下室; 3)向第一室加入另外的试剂并关闭所述室; 4)使下室或上室中的至少一个使得使所述一种或多种第一试剂或所述另外的试剂参与第一反应或达到所需反应条件的条件; 5)使所述反应容器受到离心力,以便将所述另外的试剂驱动到下室中并允许其与下室的内容物相互作用; 其中至少步骤(2)至(5)自动进行。 该方法允许在不打开容器的情况下在容器中进行多个步骤。 特别适用于PCR反应。

    • A microplate assembly comprising a multi-well microplate, a plurality of vent caps and a porous vent film. The microplate includes a frame that houses a plurality of open wells in a rectangular array. Vent caps mount on the microplate to seal and vent the wells. When the vent caps are coupled to the wells, an interior volume is formed in each well. The wells function as a vessel for liquid samples that occupy predetermined spaces within the interior volumes. The liquid samples remain within its predetermined space for all orientations of the microplate assembly. The vent cap comprises an array of well inserts. Each well insert comprises a sealing plug and a vent tube. The well inserts are interconnected by a perforated web. The sealing plugs form a seal at the mouth of the open wells. The vent tubes, which are fixed to the sealing plugs, terminate in a vent that communicates with the interior volumes outside the predetermined spaces occupied by the liquid samples. The vents permit the pressure within the interior volume to be equalized with the ambient pressure via a passage that runs through the vent tube and the sealing plugs. Material may be added to or removed from each well without removing the vent cap. The porous vent film, which has an adhesive coating, adheres to the vent caps while covering the passages, thereby inhibiting evaporation of the liquid samples.
    • 微板组件包括多孔微板,多个通气帽和多孔排气膜。 微孔板包括容纳多个矩形阵列的开放井的框架。 通气盖安装在微板上以密封和排出孔。 当通气盖连接到井时,在每个井中形成内部容积。 这些孔用作在内部容积中占据预定空间的液体样品的容器。 液体样品保留在其预定空间内用于微板组件的所有取向。 排气盖包括一系列井插件。 每个井插件包括密封塞和排气管。 井插入物通过穿孔网互连。 密封塞在开口孔的口处形成密封。 固定到密封塞上的排气管终止于与液体样品占据的预定空间外的内部容积连通的排气口。 通风口允许内部空间内的压力经由通过通气管和密封塞的通道与环境压力相等。 可以将材料添加到每个孔中或从每个孔移除,而不移除通气盖。 具有粘合剂涂层的多孔通气膜在覆盖通道的同时粘附到通气盖上,从而抑制液体样品的蒸发。
