Fluid processing apparatus has a prefabricated branched network of flexible tubing, for conducting process fluid between process elements of the apparatus, and control valves. A tubing support has opposable front and rear plates which define a pattern of support channels between them in which the flexible tubing network lies, so that the support channels limit or prevent expansion of the flexible tubes. Standard non-reinforced tubing can then be used for high-pressure work. The support body plates can be separated to open the channels for insertion or removal of the flexible tubing. The front plate may be transparent. The control valves operate by simply pressing on the tubing in the support channels to block flow, without invasion of the flow path. The tubing sets can be easily replaced, cleaned or sterilized. The invention is useful in a range of controlled-flow processes e.g. chromatography and filtration. |
