Apparatus for filling an electrophoresis cassette of the type having a gel layer between two glass plates. The filling system includes a filling manifold which is brought into abutment with the bottom edges of the glass plates. A rubber gasket provides a seal between the manifold and the cassette, The gasket includes a trough extending along the bottom edge of the cassette which communicates with an opening adapted to receive an injector. Liquid gel material in the injector fills the cassette from the bottom to the top.

Electrophoresis cassette system with apparatus and method for filling

An electrophoresis cassette system which when used with a detector can automatically perform an analysis of radio-labelled molecules. The cassette system is easily assembled and may be reused. The cassette includes a new type of side spacer which incorporates nylon monofilament and which includes a buffer zone for increased accuracy. A new clamp and other improvements further enhance the accuracy of the cassette and reduce variations in the electric field at the bottom and sides of the cell to provide increased accuracy. A new cassette filling system is shown for use with the cassette which permits rapid filling of a cassette with gel material while providing a more uniform gel layer than was previously attainable.
