— PROGRAMMABLE PEF GENERATOR
If your protocol changes every few weeks,
your pulse generator shouldn't be the thing slowing you down.
The PEF-2500 Mono/Bi-Φ puts the waveform engine inside the instrument, and gives you the front panel. Reconfigure voltage, phasing, timing, and electrode maps from the touchscreen, no vendor call required.

— ON THE TOUCHSCREEN
What you can change yourself
No hardware swaps. No vendor callback. Reprogram the waveform and run.
Monophasic or Biphasic
Switched per profile. No hardware change required.
Output range
10–80 A across the full voltage window.
Pulse width
Phase-to-phase delay from 8 to 1000 µs.
Pulses per packet, packets per sequence
Packet delay adjustable out to 10 seconds.
Pulse-to-pulse delay
Set independently for each pulse in the sequence.
Multielectrode option
Channels paired per pulse for complex geometries.
See the interface, not just the specs
A short walkthrough of the touchscreen: selecting a profile, adjusting voltage and pulse width, and stepping through charge, enable, ablate, and discharge. This is what a researcher actually sits down in front of.
— BUILT FOR THE WAY RESEARCH WORKS
Every state staged, shown, and interlocked
Charge, enable, ablate, discharge. Each state is staged in hardware, displayed on screen, and interlocked before the next one is allowed.
Charge
Capacitor bank brought to the programmed voltage under closed-loop control.
Enable
Output stage armed. Interlocks confirmed before any energy can be delivered.
Ablate
Programmed pulse sequence delivered exactly as defined in the active profile.
Discharge
Residual energy safely bled down before the system returns to standby.
— WHO’S USING IT
One instrument, several benches

Electroporation
Pulsed field ablation research
Bioprocessing
Non-thermal food & liquid treatment
Plasma work

— PART OF A FAMILY
Match the instrument to the work
The PEF-2500 is one of four systems, so you can match voltage and current range to the work instead of the other way round.
PEF-1500
Lower-voltage bench system for early-stage protocol development.
PEF-2500
1.0–2.5 kV, 10–80 A. The most common configuration across research applications.
PEF-3000
Extended voltage range for higher-energy ablation and bioprocessing work.
PEF-3500
Top of the range, for applications that push past standard PEF envelopes.
