1. Power supply (structure and working principle of electrophoresis machines)
This product adopts serial-type electronic stabilizing circuit,whose basic structure is as follows:
Main circuit is a voltage doubling rectifying ciecuit made of silicon diode and electrolytic capacitor; BU4515 large power switch triode as pass element; 2M358 as comparison amplifier; sampling circuit made of output regulation potentiometer and divider resistance, with 2CW233 as reference voltage, to guarantee the stable output voltage of instruments.
2. Uses
Electrophoresis machines is an absolutely necessary machines for checking and analyzing in medical, scientific research and other test field.
They can be used for filter paper, cellulose acetate electrophoresis.
3. Instruction:
The machines must be grounded and connected correctly according anode and cathode before the power on.
Do not touch the electrodes and matter in the eletrophoresis tank in order to prevent from shocking during the power on. . Warni! The output end must not be shorted so as not to damage parts. When output short circuit happens or output current exceeds 100mA,the100mAfuse installed on circuit board inside machine will cut out and both voltmeter and ammeter show zero. When change fuse, please check if short circuit happens at output end. The machine can be started only when all faults have been cleared.
Choose voltage value according your requirement.
Turn on the power, and the indicator light. turn the adjustable voltage knob to obtain the appropriated output voltage value for eletrophoresis.
