Electrophoresis is an important laboratory practice used in many fields of science, including molecular biology and electrical engineering. This technique is used to separate, detect and purify molecules and macromolecules. The accuracy and precision of the results are strongly affected by the equipment used during the electrophoresis process. While there are a variety of power supplies that can be used for an electrophoresis session, not all will guarantee the same levels of accuracy.
At Kalstein, a leading manufacturer of precision scientific equipment, we offer a variety of high-precision power supplies specifically designed for electrophoresis laboratory work. As a result, laboratories must use power supplies that can guarantee the necessary precision. To that end, this article discusses which power supplies can be used effectively and can guarantee maximum precision for electrophoresis experiments.
Characteristics of power supplies
A power supply is the device that is the last line of defense linking the electrophoretic device to the power outlet. Its main function is to provide power to the electrodes in electrophoresis laboratories. This means that it must guarantee a constant current, which translates into constant precision and high resistance to noise. It should be noted that this power supply must be compact enough to be installed in the electrophoretic wedge, which means looking for a design that is as simple and robust as possible.
The high-performance power supplies offered by Kalstein have a manual and automatic precision that cannot be matched by other power supplies. These power supplies have unique voltage and current tracking technology, so that the user can adjust the voltage, current, switching frequency, waveform and pulse width by simply turning a dial. This means that the results obtained will not only be accurate but also error-free because the user can adjust the system in real time without the need for laborious techniques.
Popular power supplies
One of the most commonly used power supplies in electrophoresis laboratories is the DC power supply, a device capable of delivering DC current to a resistor, typically between 0.5 and 5.0 V. This ensures current stability during the experiment. This power supply, also known as a linear power supply, features a simple design and efficient performance that make it ideal for laboratories. Another less common power supply, but also effective for electrophoresis experiments, is the common anode power supply, capable of delivering both positive and negative voltage to obtain current stability at the laboratory electrodes.
In addition, Kalstein’s patented open-loop control technology also helps to maximize the accuracy of electrophoresis results. This is achieved by continuously monitoring the electronic parameters and automatically correcting any possible unexpected results before they are recorded. This solution is useful for users as it minimizes supersaturation, overcurrents and overvoltages in real time, while improving overall electrophoresis performance.
Precautionary measures
It is important to remember that a reliable power supply is vital to ensure accuracy in electrophoresis procedures, so steps should be taken to ensure that quality equipment is chosen. This means studying the specification of the power supply to ensure that they have been certified to industry quality standards. In addition, the warranty offered by the manufacturer and the cost of the equipment should also be considered.
In conclusion, it is critical to ensure a reliable power supply when performing electrophoresis experiments. DC power supplies are the most common and reliable option, as they allow constant current delivery without major fluctuations. In addition, these devices are relatively easy to install and their simple design ensures high performance in electrophoresis laboratories. To obtain the best results, in addition to studying the quality specifications, the cost and warranty offered by the manufacturer should also be considered.
Advantages of choosing a Kalstein brand power supply
After considering all these factors, laboratories can find the right power supply for maximum accuracy in their electrophoresis experiments. In addition to providing increased accuracy, Kalstein technology also offers numerous options for automatic top and bottom load regulation. This means that independent regulation of the top and bottom of the load can be performed without the need for additional cables. This is of great help to users as it makes it easier to achieve the perfect calibration for any application. This ensures that the results obtained are error-free.
At Kalstein, our power supplies are designed to operate in all types of environmental conditions. This means that our equipment is resistant to dust, water, shock, impact and other external factors, ensuring reliability and reduced maintenance requirements. These qualities make Kalstein equipment ideal for electrophoresis laboratories operating in harsh environments; decide for yourself at the following link HERE.
