Abstract

A device for analysis of a sample, the device comprising: a first layer having a network of passages and chambers through which fluid is caused to flow during analysis; a second layer in which a plurality of chambers are formed, the chambers containing fluids for use in the analysis; an inlet in either the first or the second layer into which a sample to be analysed can, in use, be placed, and a third layer providing a frangible fluid seal between the chambers of the second layer and the network of the first layer so that, in use, a break in the third layer permits fluid from a chamber in the second layer to pass into the network of the first layer to enable analysis of the sample to be carried out.
