Product code: OC-725C-V
Designed for two-electrode voltage clamping (TEVC) of Xenopus oocytes and other large cells.
An amplifier designed for two-electrode whole-cell voltage clamping of large cells (Xenopus oocytes) and cell structures (squid axons). Measurements can then be recorded via a PowerLab and LabChart data acqusition system, which is purchased separately. This two-electrode voltage clamping (TEVC) amplifier features:
