For solving the above problems, the utility model provides a kind of cooled with liquid nitrogen formula electrophoresis chamber.This cooled with liquid nitrogen formula electrophoresis chamber adopts the automatic control agent temperature of liquid nitrogen, can make experimentation carry out under optimal temperature.
The technical scheme that the utility model technical solution problem adopts is: invent a kind of cooled with liquid nitrogen formula electrophoresis chamber, be characterized in, cooled with liquid nitrogen formula electrophoresis chamber has an electrophoresis major trough, installing electrodes support in the electrophoresis major trough, groove install one on electrode suppor on, the electrophoresis chamber lid is installed on electrophoresis major trough top, cover positive electrode and negative potential are installed at electrophoresis chamber, cover mounting temperature sensor at electrophoresis chamber, temperature sensor connects a controller by wire, in the inner refrigerator pipes of installing of electrophoresis major trough, refrigerator pipes connects a magnetic valve, magnetic valve is arranged on the electrophoresis major trough, magnetic valve passes through wire connection controller.
The beneficial effects of the utility model are that the utility model, for Biochemistry Experiment, in particular for isolated protein, can adopt the automatic control agent temperature of liquid nitrogen, can make experimentation carry out under optimal temperature.Thereby can effectively improve quality of experiments.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is the front view of the present embodiment, and accompanying drawing 2 is left views of the present embodiment.
1 electrophoresis major trough in figure, 2 arc-spark stands, 3 holding bolts, 4 electrophoresis chamber lids, 5 positive electrodes, 6 temperature sensors, 7 positive electrode wires, 8 temperature sensor lead, 9 double glazing units, groove on 10,11 negative potential wires, 12 negative potentials, 13 electrode plugs, 14 magnetic valves, 15 liquid nitrogen pipe, 16 magnetic valve wires, 17 controllers, 18 refrigerator pipes.
Embodiment
As shown in Figures 1 and 2, arc-spark stand 2 is installed in electrophoresis major trough 1, be connected with groove 10 on arc-spark stand 2, holding bolt 3 is pressed on double glazing unit 9 on arc-spark stand 2 and upper groove 10, electrophoresis chamber lid 4 covers on electrophoresis major trough 1, on electrophoresis chamber lid 4, positive electrode 5 is installed, negative potential 12 and temperature sensor 6, positive electrode 5 and negative potential 12 are connected on electrode plug 13 by positive electrode wire 7 and negative potential wire 11 respectively, temperature sensor 6 is connected on controller 17 by temperature sensor lead 8, refrigerator pipes 18 is connected on magnetic valve 14, magnetic valve 14 is arranged on electrophoresis major trough 1, liquid nitrogen pipe 15 is installed on magnetic valve 14, magnetic valve 14 is connected with controller 17 by magnetic valve wire 16.
Adopt conventional electrophoretic separation working method during use, at first take off electrophoresis chamber lid 4, take out utmost point frame 2 from electrophoresis major trough 1, from utmost point frame 2, take off at double glazing unit 9, prepare gel in double glazing unit 9, then double glazing unit 9 is arranged on arc-spark stand 2, with holding bolt 3, double glazing unit 9 is pressed on arc-spark stand 2 and upper groove 10, by the arc-spark stand 2 electrophoresis major trough 1 of packing into, add damping fluid respectively in electrophoresis major trough 1 and upper groove 10, the sample that adds needs to separate in the sample cell of gel, electrophoresis chamber lid 4 is covered on electrophoresis major trough 1, electrode plug 13 is inserted to electrophoresis apparatus and start electrophoresis, during electrophoresis under the effect of electric current damping fluid and gel can generate heat, opening controller 17 power supplys now, pass into liquid nitrogen on liquid nitrogen pipe 15, temperature sensor 6 is converted into electrical signal by temperature signal and sends into controller 17, controller 17 sends the control electrical signal according to temperature signal to magnetic valve 14, when temperature during higher than set(ting)value magnetic valve 14 open, liquid nitrogen is introduced from liquid nitrogen pipe 15, spray into refrigerator pipes 18 through magnetic valve 14, make the interior temperature of electrophoresis major trough 1 reduce, thereby reduce the temperature of damping fluid and gel, when the interior temperature of electrophoresis major trough 1 during lower than set(ting)value, controller 17 controls magnetic valve 14 and cuts out, by magnetic valve 14, open, the alternating movement of closing is controlled at the interior temperature of electrophoresis major trough 1 in optimum range.
