A compact impedance analyzer with an open path to your setup
The ISX-3 combines a high-performance IF frontend with the ExtensionPort and the Sciospec software suite — a foundation that supports research workflows today and customer-specific OEM front-ends tomorrow.
IF frontend
mΩ … TΩ COVERAGE
Lab-grade impedance over an extreme dynamic range
The ISX-3 IF frontend covers 100 mHz to 10 MHz out of the box and can be extended to 40 MHz or 100 MHz. It supports 2-, 3- and 4-electrode setups with mΩ to TΩ measurement range and up to ± 1 V DC bias.
ExtensionPort
USER-ACCESSIBLE INTERFACE
A direct path for application-specific front-ends
The ExtensionPort exposes 2/3/4-electrode signals, supply rails and digital IOs (optionally I²C or UART). It simplifies custom development built on or around the ISX-3 — from chip carriers to OEM front-ends.
Sciospec software
SUITE + COM API
Control and automate from any environment
The included Sciospec software suite handles measurement setup, data export and analysis. A COM interface integrates the ISX-3 with Java, C, Python, LabVIEW, MATLAB and similar environments for automated workflows.

Where the ISX-3 fits in
From bioimpedance and biosensor R&D to materials and process monitoring, the ISX-3 has become a standard tool wherever reliable, broadband impedance spectroscopy is needed.
Bioimpedance & cell-based assays
Track cell barrier formation, drug response and cytotoxicity with reproducible EIS — from single-electrode experiments to chip-based assays via the ExtensionPort.
Biosensors & EIS-on-chip
Characterize electrodes, surfaces and binding events. The ISX-3's 2-/3-/4-electrode flexibility and wide impedance range make it a default tool for biosensor development.
Materials & electrochemistry
Run impedance spectroscopy on coatings, electrolytes, batteries and corrosion systems with mΩ to TΩ coverage and lab-grade precision.
Process, food & plant tissue
Use EIS to monitor liquids, tissue conductivity and process states — including published work on pulsed electric field treatment of plant tissue.

Details
From a benchtop ISX-3 to your integrated product
The ISX-3 isn’t only a lab instrument — it’s a measurement core that has been integrated into many customer products. The ExtensionPort exposes the relevant signals and digital interfaces so application-specific front-ends can be built on or around the ISX-3 without re-inventing the EIS engine.
When you’re ready to move from a benchtop unit to a product, we help migrate the ISX-3 architecture into dedicated OEM electronics — with tailored firmware, connectors and certifications for your target environment.

Benchtop validation
Validate your method on a standard ISX-3 with cables, fixtures and the Sciospec software suite.
- 02
Application-specific front-end
Attach an ExtensionPort front-end tailored to your sensor, chip or fixture.
- 03
Embedded OEM platform
Migrate the ISX-3 measurement core into a dedicated OEM module with custom electronics and firmware.

Individual FAQ
Short technical answers to the questions we hear most often about the ISX-3.
What frequency range does the ISX-3 cover?
The standard IF frontend covers 100 mHz to 10 MHz. Extended hardware options reach 40 MHz or 100 MHz for higher-frequency biosensor and materials work.
Which electrode configurations are supported?
2-, 3- and 4-electrode setups are user-selectable. Combined with the mΩ … TΩ impedance range, the ISX-3 fits everything from low-impedance electrochemistry to high-impedance biosensors.
How do I attach a custom sensor or chip?
Through the ExtensionPort. It exposes the 2/3/4-electrode signals, supply rails and digital IOs (optionally I²C or UART) — so you can build application-specific front-ends without modifying the ISX-3 itself.
Can the ISX-3 be automated from Python or MATLAB?
Yes. The COM interface integrates the ISX-3 with Java, C, Python, LabVIEW, MATLAB and similar environments. The Sciospec software suite is included for standalone use.
Is multichannel measurement possible?
Sequential multichannel measurements are possible via internal multiplexer options. For true parallel channels with full electrochemistry support, the CSX-64 multichannel potentiostat is the right platform.
