Abstract
A gel pump operated by a stepper motor may be used to deliver fresh gel to one or more capillaries through one or more manifolds and valves. By controlling the valves, fresh gel delivered by the pump will replace the old gel in the capillaries for an automated gel replacement system. In a different setting of the valves, the manifolds may be purged of the old gel prior to delivery of fresh gel to the capillaries. The gel delivery system may also be combined with an electrophoresis system so that sealing connection capable of withstanding high pressure adequate for gel injection need not be frequently broken when the gel is to be replaced. Manifold/reflector assembly is advantageously used in the system that facilitates electrical circuit for electrophoresis and for gel replacement.
