| abstract |
A microfluidic device comprising one, two or more microchannel structures ( 101 a - h ), each of which comprises a reaction microcavity ( 104 a - h ) intended for retaining a solid phase material in the form of a wet porous bed. Each of said one, two or more microchannel structures comprises the solid phase material in a dry state together with a bed-preserving agent comprising one or more compounds having bed-preserving activity. |
