A dilution system comprises a first manifold 1 for the supply of a diluents, a second manifold 25, a tube 5 extending from the first manifold 1, an inlet tube 7 for a sample to be diluted which merges with the tube 5 from the first manifold to form a combined tube 15 in which the sample is diluted with the diluents and means for connecting an outlet 23 of the combined tube 15 to the second manifold 25. The inlet tube 7 and the tube 5 may be connected by way of a Y-connector 9. The combined tube may be split into first 21and second branches 23 with at least one of the branches connecting to the second manifold. Preferably the cross-sectional area of each combined tube 15 may be twice the cross-sectional area of the first and second branches which extends from the manifold. Mixing means, such as baffles, may be provided in each combined tube.
