    • A solid phase organic synthesis device comprising a manifold and an optional heating block mounted to an upper surface of the manifold. The manifold includes an internal cavity and a first array of holes coupled to the internal cavity. The heating block includes a second array of holes vertically aligned with the corresponding holes of the first array. The first and second arrays of holes are adapted to accommodate flow-through reaction vessels. Each reaction vessel is secured in one of the holes of the first array and a vertically-aligned one of the holes of the second array. The interiors of the reaction vessels are in communication with the internal cavity of the manifold. The flow-through reaction vessels, which contain solid phase resins for solid phase organic synthesis, are controlled by regulating the pressure within the manifold. The manifold includes a pressure port coupled to both an inert gas source and a pressure control device, and a vacuum port coupled to a vacuum control device and a vacuum source. The pressure control device and the vacuum control device are easily operated to create a vacuum and varying degrees of positive pressure within the manifold, as required when carrying out an organic synthesis. A second manifold is mounted on the first manifold in the absence of the reaction vessels for supplying inert gas used to concentrate organic synthesis products.
    • 一种固相有机合成装置,包括一个歧管和一个安装在歧管的上表面上的任选的加热块。 歧管包括内腔和连接到内腔的第一阵列孔。 加热块包括与第一阵列的相应孔垂直对准的第二孔阵列。 孔的第一和第二阵列适于适应流通的反应容器。 每个反应容器固定在第一阵列的一个孔和第二阵列的垂直对齐的一个孔中。 反应容器的内部与歧管的内腔连通。 含有用于固相有机合成的固相树脂的流通反应容器通过调节歧管内的压力来控制。 歧管包括联接到惰性气体源和压力控制装置的压力端口以及耦合到真空控制装置和真空源的真空端口。 压力控制装置和真空控制装置易于操作,以在进行有机合成时根据需要产生真空和歧管内的不同程度的正压。 在没有用于供应用于浓缩有机合成产物的惰性气体的反应容器的情况下,第二歧管安装在第一歧管上。
