Abstract
The disclosed invention relates to a cell unit for use in observing an electophoresis which utilizes a measurement cell which accommodates a liquid specimen. A pair of conduit elements are used to introduce and discharge the liquid specimen into and from the measurement cell with one of the conduit elements having a flexible tube portion. Also included is a pair of valves for closing a pair of conduit elements with at least one of the valves being utilized as a pinch valve to pinch the flexible tube. A pair of housing elements accommodate a pair of electrodes with the electrodes producing an electric potential gradient in the specimen. Lastly, a pair of diaphragm elements are each disposed between the measurement cell and one of the pair of housing elements in order to separate a space in the measurement cell from the space in the associated housing element. One of the pair of diaphragm elements is disposed in order to absorb a fluctuation of pressure in the liquid in a particular space defined by the pair of diaphragm elements and the valves in order to securely and easily seal the liquid specimen within the space defined by the pair of diaphragm elements and the valves. The device is also used to minimize the flow of liquid specimen within the measurement cell after sealing.
