Abstract: A flow apparatus for measuring at least one biophysical property of one or more components is provided. The apparatus comprises one or more microfluidic devices. Each microfluidic device comprises: a sample channel having a sample inlet port for introducing a sample fluid flow comprising one or more components at a first flow rate into an elongate distribution channel, an auxiliary channel having an auxiliary inlet port for introducing an auxiliary fluid flow at a second flow rate into the elongate distribution channel. The distribution channel is configured to enable a lateral distribution of the components from the sample fluid flow into the auxiliary fluid flow. Each microfluidic device further comprises two or more capillary channels provided downstream and in fluid communication with the distribution channel, at least one outlet port provided downstream of each of the capillary channels.

Abstract: A sealing assembly creating a sealed flow path between fluid ducts. The seal assembly comprises a housing and a tubular element within the housing providing a fluid conduit between the fluid ducts. Two sealing elements each have an internal sealing face sealably engaged with the tube and an external face for sealing, in use, with a respective fluid duct. At least one of the sealing elements is slidable with respect to the tubes. A support is slidably retained by the housing, surrounds one end of the tube and supports one of the slidable sealing elements on the side of the sealing element opposite to its external face. A resilient element within the housing biases the support so as to urge the two sealing elements apart.

Abstract: A reactor device (100) for reaction fluid comprising a reaction vessel (102) comprising: an end cap (104) comprising at least one passage (112) for the reaction fluid; and at least one tube (116) which extends through the reaction vessel (102). The reaction vessel is operable to receive a control fluid outside the at least one tube (116) for controlling the temperature inside the at least one tube (116). A manifold (200) is connectable to the end cap (104) and comprises at least one channel (206) for reaction fluid. An outlet (208) from the manifold (200) is in fluid communication with the tube (116). The end cap (104) has a thermal conductivity of greater than 1 watt per square meter kelvin to provide a thermal coupling between the control fluid and the manifold (200).
