CUY21EDIT Electroporator

CUY21EDIT Electroporator


Automated Current Measurement

Electric current is the major factor to obtain successful electroporation results. The CUY21EDIT makes it possible to measure and display such current automatically. The output current information remarkably helps you optimize your electroporation experiments.

Impedance Measurement

The CUY21EDIT easily enables you to measure impedance (electric resistance) of the target sample and automatically displays it. The fluctuation in resistance value results in changes in current value and as a result it affects the reproducibility of experiments. In order to deliver the optimal current, you need to know the actual resistance of the target sample before electroporation. Because in vivo resistance is less stable than in vitro in general, the impedance value which is measured prior to in vivo electroporation is the important criteria to determine whether the experiment is going well.

Accurate Low Voltage Square Wave Pulses

The CUY21EDIT is designed to output precise low voltage square wave pulses. The accurate and low voltage square wave pulses bring high transfection efficiency and less damage. The Voltage can be set from 1V to 500V in 1V increment.

Wide Applications In Combination With A Variety of CUY Series Electrodes

The CUY21EDIT can be used with more than 250 NEPA GENE’s CUY series electrodes which make it possible to do a wide range of electroporation experiments. And custom-made electrodes are easily ordered and available for this CUY21 electroporator. It enables you to realize the experiments which you have actually desired.

Safety Function

The CUY21EDIT has the safety function. If the current flows beyond the limit, This CUY21 electroporator is shut down automatically. This safety function protects the user from the electrical accidents. This CUY21 electroporator also has other unique safety functions. One is the warning beep prior to the pulse output. The other is that red indicator on the front panel lights up during electroporation.

Automatic Voltage Measurement

Actual output voltage of the CUY21EDIT can be measured after the electroporation is executed. By checking the voltage, it is easy to find out whether programmed voltage of DC pulse is generated. If not, there is something wrong with a device.
