While the basic PEF process is known since decades as stretching bacterium till its eruption by sharp pulsing electrical fields each practical case , aside of already known for clear juices , requires a process development work for finding optimal PEF pulse parameters .
For performing lab R & D we offer our bench-top PEF system as on the right . It also has broad selection of PEF parameters and two PEF chambers .
Specifically important to have a broad selection of sharp rectangular pulses with various durations ( left ) and frequencies ( right )
