Devices with a passageway for electroosmotic flow and method of making same

A device has a passageway 14 for electroosmotic flow therealong. The passageway 14 is bordered by an internal surface 12. A porous plug, 16, 18 is located in the passageway so that there are no gaps between the porous plug 16, 18 and the internal surgce12. The plug 16, 18 is made by curing a paste comprising a filler, such as glass powder, and a silicate solution. The passageway may have a maximal cross-sectional dimension of great than 500 m, a minimum cross-sectional dimension of greater than 500 m or a cross-sectional area of greater than 0.2mm<2>. The device may be used for the reaction of an aldehyde or a ketone with a dithiol, via an acid supported catalyst, to produce a 1,3-dithiane or a 1,2-dithiolane.
