Product code: TEV700-V
Provides two-electrode voltage clamping via an Oocyte Clamp Amplifier and the necessary components typically used with in research involving Oocytes.
This workstation provides two-electrode voltage clamping (TEVC) via an Oocyte Clamp Amplifier and many of the necessary components typically used with in electrophysiology research involving Oocytes. Measurements can then be recorded via a PowerLab and LabChart data acqusition system, which is purchased separately.
Included with the workstation are:
Two E series electrode holders are typically required with the clamp and varying sizes can be purchased separately:
This workstation can also be purchased as part of the Two Electrode Voltage Clamp Workstation System.
Accessories (optional, purchased separately):
Our Support Articles contain answers to common questions, how-tos, solutions, and documentation.
Maximize time and resources with our customized training services delivered at your facility, on your equipment, on your terms.
