Incubation vessel support

A separator and method, particularly for use in continuous-flow analysis, for separating liquid from a mixture of a liquid phase and a solid phase. The separator includes a first conduit, and a second conduit which communicates with the first conduit across a filter, whereby liquid in the liquid-solid phase mixture in the first conduit can be pumped into the second conduit, the solid phase being held back by the filter, the filter then being back-washed with wash liquid. The liquid-solid phase mixture may be segmented, the segments being separated by occluded air, or air and wash liquid segments, the back-washing then being controlled to occur while the air and/or wash liquid traverses the filter.

Phase separator for continuous-flow analytical systems

Method and apparatus suitable for automatic assay of fluid samples, particularly immunoassays, in which a reaction product of the assay is bound to a magnetically attractable particle and separated from the reaction mixture by use of a magnetic trap. The method and apparatus are of especial use in radioimmunoassays carried out in an automated continuous-flow manner.
