ABSTRACT:
A device and method are disclosed for conducting a reaction, such as an extraction reaction. The device is flexible and provides contained compartments with pre-incorporated liquids. The liquids are reliably moved past temporary barriers by constructing the barrier to be a relatively thin sheet that bursts preferentially compared to seals between the sheet and the rest of the material defining the compartments.
