<p>Extraction devices are known which comprise a burstable reaction chamber and a flow passage between an inlet and an outlet aperture. In these devices, the reaction chamber bursts at a seal. The force needed to burst this seal may vary from cuvette to cuvette due to variances in sealing conditions. Described herein is an improved extraction device (10) which is flexible and provides compartments (20, 22, 24) with pre-incorporated liquids. The liquids are reliably moved past temporary barriers by constructing the barrier to be a relatively thin sheet which bursts predictably compared to seals formed between the thin sheet and the rest of the material defining the compartments (20, 22, 24). <IMAGE></p> |
