EPS-300R
Compact Rechargeable Power Supply
The everyday supply for agarose gels and teaching laboratories, with its own battery.
The EPS-300R brings the EPS-650R's battery operation and run control to a smaller footprint. It covers the 20–300 V range used for agarose and most nucleic acid work, and is the natural choice for teaching laboratories where several groups run gels at once.
