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.

Abstract translation: 由步进电动机操作的凝胶泵可以用于通过一个或多个歧管和阀将新鲜的凝胶递送到一个或多个毛细管。 通过控制阀门，由泵输送的新鲜凝胶将替代毛细管中的旧凝胶，用于自动凝胶置换系统。 在阀的不同设置中，在将新鲜凝胶递送至毛细管之前，歧管可以被清除旧凝胶。 凝胶递送系统还可以与电泳系统组合，使得当要更换凝胶时，不需要频繁地破坏能够耐受用于凝胶注射的高压的密封连接。 歧管/反射器组件有利地用于便于用于电泳和凝胶置换的电路的系统中。
