Electrophoresis tank with accurate and controllable liquid level

Abstract

The invention discloses an electrophoresis tank with an accurate and controllable liquid level. The electrophoresis tank comprises an electrophoresis tank cover (2) and an electrophoresis tank body (4), wherein the electrophoresis tank cover is provided with an electrophoresis sample inlet (1), an electrode fixing port (3) and a replenishing liquid inlet (5), a liquid replenishing pump (9) is connected with a liquid storage tank (12) and the replenishing liquid inlet (5), an electrophoresis liquid circulating inlet (7) and an electrophoresis liquid circulating outlet (6) are formed in two sides of the electrophoresis tank body (4), a connecting pipeline (11) of the electrophoresis liquid circulating inlet (7) and the electrophoresis liquid circulating outlet (6) is provided with a circulating pump (10) for connection, and the electrophoresis liquid circulating inlet (7) is communicated with a liquid level monitor (8). Manual or automatic liquid supplementing is achieved by monitoring the liquid level height of the electrophoresis tank, and powder agglomeration and deposition are prevented by arranging the circulating pump to circularly stir electrophoresis liquid.

Description

AI Technical Summary

Problems solved by technology

Most electrophoretic equipment requires the electrophoretic fluid to be a solution or a stable suspension system. In order to obtain a stable electrophoretic system, it is often necessary to modify the surface of the powder or add various surfactants and suspending agents to the electrophoretic fluid, which will make the preparation of the electrophoretic fluid complicated. At the same time, a variety of organic impurities will be introduced into the deposition layer. At the same time, because many electrophoretic systems use volatile liquids such as methanol and ethanol as solvents or the liquid level is prone to change due to electrophoresis consumption, it is difficult to accurately control the height of the electrophoretic layer.
