Electrophoresis introduces common problem solving

Frequently Asked questions about electrophoresis devices
The output of the electrophoresis apparatus cannot reach the set value
Answer: The state of the output value of the electrophoresis instrument follows ohm's law: voltage U= current I× (electrophoresis tank) resistance R
When the resistance R is relatively constant, any one of the parameters in U, I and P (power P= current I× voltage U) is constant, and the other parameters are also constant; And if any one parameter changes, the other parameters will also change directly.
If the output voltage U of the electrophoresis apparatus cannot reach the preset value, it should be observed first whether I or P has been constant, or has reached the large I or P specified by the electrophoresis apparatus (JY electrophoresis apparatus has clear indicator sign). If the limit has not been reached, turn up the setting that has been constant I or P (to the limit if necessary) to increase the voltage output.
If the current I of the electrophoresis apparatus does not reach the preset value, the voltage U or power P can be adjusted.
If the power P of the electrophoresis apparatus does not reach the preset value, the voltage U or the current I can be adjusted.
Computer control electrophoresis instrument overvoltage alarm
(1) Check whether there is no load.
(2) Whether there is no buffer in the electrophoresis tank.
(3) Whether the platinum wire of electrophoresis tank is broken.
Overcurrent protection
(1) Whether there is short circuit in the electrophoresis tank.
(2) Whether the buffer is wrong.
Leakage protection
(1)whether there is liquid splash into the instrument or output interface.
(2) Whether a lot of dust falls into the inside of the instrument.
