    Galvanic isolation
    Galvanic Isolation of each channel is needed, if you want to use your potentiostat with other potentiostats in the same cell or want to use it for Zero Resistance Amperometry. Without galvanic isolation it is not possible to operate multiple 2- or 3-electrode systems in the same cell. Galvanic Isolation makes each channel electrically floating compared to other channels and ground. Hence, another reason to use a floating instrument is to avoid ground loops. Furthermore if you want to use your EmStat or PalmSens as a Zero Resistance Ammeter (ZRA), it needs to be floating. With a ZRA you are measuring a current without changing it. There is, however, a disadvantage of galvanic isolation: The noise protection is drastically reduced. Usually all conducting shields connected to the ground act as a Faraday cage for the device and protect it against noise. If the connection between the chassis and the potentiostat is removed, the chassis no longer acts as a Faraday cage for the potentiostat. We recommend galvanic isolation only for customers, who know that they need it and are aware of the drawback.

    High-Throughput Networked Electrochemical Analyzer

    The RackMount 16CH is a high-performance 16-channel potentiostat built on the industry-proven EmStat4 LR platform. Engineered for high-throughput electrochemical research, it delivers precise, simultaneous measurements across all channels without compromise. Equipped with an embedded Lablink controller, the RackMount 16CH manages, buffers, and stores every data point locally. Your experiments remain uninterrupted and your data stays safe.

    Connect electrochemical cells or disposable electrodes

    16 independent channels

    Each quad-cell connector interfaces with four independent electrochemical cells. Every channel features its own dedicated potentiostat with discrete Reference Electrode, Working Electrode, Counter Electrode, and ground connections for total isolation and control. Galvanic Isolation across the channels and hardware synchronization allow for using multiple Working Electrodes in the same cell.

    Sharing, buffering and storage

    Embedded Lablink controller

    The RackMount 16CH, powered by Lablink, controls your measurements internally and logs them directly to its onboard Solid State Drive (SSD).

    • Independent Operation: Experiments run flawlessly without a PC connection.
    • Internal Logging: Data is saved locally, eliminating the risk from software interruptions.
    • Seamless Recovery: Simply reconnect to review and download your secured results
    Status information at a glance

    Status indicators and display

    Each channel of the RackMount 16CH has a status indicator LED, showing if channels are available or claimed by users or if a measurement is running. The RackMount 16CH display shows Lablink-related status information and the fan speed.

    Instant-start sensing

    Automatic droplet detection

    Optimized for Screen-Printed Electrodes (SPEs), each channel can be configured via software to trigger measurements automatically upon droplet detection. This minimizes the delay between
    sample deposition and data acquisition, ensuring you capture the most time-sensitive electrochemical responses. It can also help streamline high-throughput workflows.

    Efficient wiring

    Adapter with shared Reference and Counter electrodes

    Every RackMount 16CH includes four cell-connector adapters as standard. These DB25 interfaces internally bridge the Reference (RE) and Counter (CE) electrodes for each four-channel bank, eliminating the need to manually stack leads at the cell.
