Detecting light in a capillary electrophoresis optical system includes input and output windows in the outside surface of a capillary tube. The width of the windows is not substantially greater than the bore of the tube. A fiber optic input is spaced from the capillary tube so that the light is directed to the tube and is matched to the window width. The light output from the tube is matched to be received by a fiber optic output spaced from the capillary tube. The optical light envelop from the fiber input through the tube and to the fiber output is governed by the LaGrange Invariant. The matching is effected in accordance with the Numerical Aperture of the fiber optics.

Capillary electrophoresis detection

A method and apparatus for removing a flexible layer from a substantially flat mold or other surface. A curvilinear removal head, including a vacuum manifold holding one end of the flexible layer, pivots to peel the flexible layer from the mold.

Method and apparatus for separating a layer of flexible material from a

An electrophoretic gel container. The device includes a base and a cover. The gel is adherently bound to a backing sheet. The cover is positioned to clamp the backing sheet between it and the base. The cover is spaced from the gel.
