Vertex.20A
The Vertex.20A is a versatile entry-level potentiostat which has ±20A/±2V compliance and optional integrated impedance analyser up to 1MHz.
The Vertex.20A has a peripheral port which it uses for connection to the RE and S cable. External interfacing and compatibility has some limitations when compared to the other Vertex instruments (see our compatibility table for reference).
The Vertex can optionally be expanded with a True Linear Scan module, and/or FRA/EIS capability.
Features
- Compliance: ±20A/±2V
- Optional FRA/EIS: 10µHz to 1MHz
- Optional True Linear Scan generator
