An electrophoresis device is a DC power source that provides an applied electric field for electrophoresis. Its output voltage or current or power requirements are relatively stable or vary according to specific laws.
Electrophoresis technology is an indispensable analytical tool for molecular biology research. Regarding the common problems encountered during the use of the electrophoresis system and the corresponding solutions, the brainstorming instrument will open the question and answer mode for everyone here.
Frequently Asked Question 1: Why does the output of the electrophoresis instrument not reach the set value?
1 The output state of the electrophoresis apparatus complies with the "Ohm's law": when the voltage U = current I × (electrophoresis tank) resistance R is relatively unchanged, any one of U, I, P (power P = current I × voltage U) Constant, other parameters are also constant; and any one parameter changes, other parameters also change proportionally;
2 If the output voltage U of the electrophoresis instrument does not reach the preset value, first observe whether I or P has been constant, or has reached the maximum I or P specified by the electrophoresis apparatus (JY electrophoresis has clear indicator marks). If the limit value has not been reached, the voltage output can be increased by increasing the setting of the constant I or P (if necessary to the limit value);
3 If the current I of the electrophoresis instrument does not reach the preset value, the voltage U or power P can be adjusted;
4 If the power P of the electrophoresis instrument does not reach the preset value, the voltage U or current I can be adjusted.
Frequently Asked Questions 2: Computer controlled electrophoresis instrument overvoltage alarm phenomenon, what should I do?
1 Check if no load is used;
2 Whether the electrophoresis tank is not buffered;
3 Whether the electrophoresis tank platinum wire is broken.
Frequently Asked Question 3: What is the cause of overcurrent protection?
1 Check if there is a short circuit in the electrophoresis tank;
2 Check if the buffer is wrong.
Frequently Asked Questions 4: What is the cause of leakage protection?
1 Is there any liquid splashing inside the instrument or on the output interface;
2 Is there a lot of dust falling inside the instrument?
Frequently Asked Question 5: What should I do if the fan stops or makes an abnormal noise?
Replace the fan.
Frequently Asked Question 6: There is no output of voltage and current. What should I do?
1 Check if the fuse is damaged;
2Open the chassis and check whether the plug connected to the front panel of the front panel is disconnected.
3 Check if the plug of the porcelain tank transformer is off or use a multimeter to check that the two ends of each group should be the passage.
