The present invention provides an electrochemical cell of either a primary or a secondary chemistry housed in a casing having opposed major side walls of a contoured shape. A plurality of capacitors are connected in parallel. The conductor pad transmits a positive differential signal, and the conductor pad transmits a negative differential signal; these conductor pads are disposed on the same side of the board. The matrix vessels are with elution fluid and elution fluids from the matrix vessels are extracted through their outlet openings during which the elution fluids flow through the matrices and the elution fluids which are enriched with biological material are collected in the collecting vessels. A device may lock the actuator to the housing when the actuator is aligned with the projections. The multi-component frame construction is particularly well-suited to facilitate the manufacture, shipping and assembly of BIKEBOARD\u2122 brand of hybrid bicycleskateboard vehicles.
