Beschreibung

The SEC-03M is a switched mode single electrode voltage and current clamp amplifier module for
recordings with sharp microelectrodes or suction (patch) pipettes.

Now it is possible to combine up to three SEC amplifiers in one 19 inch housing for investigating coupled cells.
Or combine an SEC-03M with a PEN-03M module for easy cell penetration or with a HVC-03M module to get a single and a two-electrode voltage-clamp system in one EPMS-housing.

SEC amplifiers are also available as 19" stand-alone devices.
