Abstract:
An electrophoretic apparatus comprising:at least three capillary tubes, each capillary tube having first and second capillary ends, and a window region formed therebetween, andan electrically insulative material having a dielectric constant greater than that of air surrounding each capillary tube along at least a predetermined length thereof, said predetermined length being situated between said first capillary end and said window region,wherein said electrically insulative material comprises at least one protective tube having at least one lumen formed therein, and said capillary tubes are situated in said at least one lumen along said first portion,said capillary tubes are arranged substantially parallel to one another along a first portion of said predetermined lengthsaid at least one protective tube is provided with a first number of lumens, each of a second number of said lumens being occupied by a single capillary tube, said second number being not greater than the first number, andat least one of said first and second number of lumens is arranged such that a collection of pairwise distances from any one lumen in that number to the remaining lumens in that number is substantially the same for all lumens in that number.
