How to Select an Electrophoresis Power Supply?

Answer the questions below to determine the most important factors in selecting your power supply.

1.Will the power supply be used for a single technique or multiple techniques?

Consider not only the primary techniques for which the power supply is being purchased,but other techniques you may use in the future. The power supply chosen for submarine gel electrophoresis of DNA may not provide the voltage or current needed for lEF electrophoresis you plan to run in six months. Likewise, the power supply that provides adequate voltage for your 45-50 cm sequencing gels may be insufficient for the 80-100 cm gels you plan to run in the future.

2. Does the power supply provide the required output?

Consider the maximum voltage, current and power requirements. A 2000 volt,100mA power supply may supply adequate voltage for some types of isoelectric focusing, but would not provide sufficient current for other applications such as SDS-PAGE or electroblotting. Also, consider the increased voltage and/or current requirements for running longer gels or multiple gels.

3. Is a constant power, constant current or constant voltage power supply required?

For optimal results,different techniques require different parameters to be held constant during the running. For example, sequencing and isoelectric focusing are best run at constant power, SDS-PAGE and electroblotting are generally run under conditions of constant current and submarine gel electrophoresis of DNS is run at constant voltage. Refer to protocol and manufacturer’s recommendations for each application.

4. Will the power supply be used to run multiple gels or single gels?

As the number of gels running off a single power supply increases current is increased proportionately. For example, single submarine gel may require 100 volts and 75 mA; two gels would require100 volts and 150mA; four gels would require 100 volts and 300mA.

5. Does the power supply have adequate safety features?

This becomes a critical requirement with high voltage power supplies where potentially lethal voltages exist.The power supplies should provide “Shut down-on-cell disconnect” and ground leakage detection to provide adequate protection to the user.

6.What are your country’s electrical requirements?

Our power supplies and gel apparatus are available in versions for 220V/50Hz operation. And our power supply is 220V±10v/50Hz±10Hz available. When ordering, please specify correct voltage, for example 220V/50Hz power supply, as well as the plug standard. We can provide American standard, British standard and European standard.

Beijing Liuyi Biotechnology Co. Ltd manufactures various power supplies for you choose, which fit for different electrophoresis techniques. For example, DYY-12 and DYY-12C are multi-purpose and full function electrophoresis power supplies. For their high voltage, they can be used for any electrophoresis experiments including IEF and DNA Sequencing Electrophoresis. With mass current, they can be operated with several large electrophoresis cells at one time, as well as blotting electrophoresis cell. For their huge power, they fit for various applications and widely be used. These electrophoresis power supplies have function of ST, Time, VH and Step model. With huge and clear LCD screen, that can be compared with high-end electrophoresis power supply overseas.The model DYY-6C, DYY-6D, DYY-12 and DYY-12C fit for testing mass quantity of samples in university student lab, as well as for testing seed purity in agriculture. These electrophoresis power supplies can be operated with several large electrophoresis cells at one time.

Below table is the key parameters of the power supply, you always can find one that meet your requirements.

And we can also classify the power supply with different parameters.

Voltage: The electrophoresis power supply can be classified as super high voltage 5000-10000V, high voltage 1500-5000V, middle high voltage 500-1500V and low voltage below 500V;

Current: The electrophoresis power supply can be classified as mass current 500mA-200mA, middle current 100-500mA and low current below 100mA;

Power: The electrophoresis power supply can be classified as high power 200-400w, middle power 60-200w and low power below 60w.

The Beijing Liuyi brand has more than 50-year history in China and the company can provide stable and high-quality products all around the world. Through years of development, it is worthy of your choice!

We are now looking for partners, both OEM electrophoresis tank and distributors are welcomed.
