Sage Science‘s Pippin Pulse electrophoresis power supply brings field inversion to your lab’s agarose gel apparatus. The system resolves DNA to 100 kb and beyond, without unwieldy instrumentation and chillers. Pulsed-field protocols are programmed by users and run from a PC, providing users the flexibility to develop protocols to meet specific applications. The operating range is 25-175V, and up to 200 mA.
