Overview

Small volume test cell for liquid electrolytes. Benefit from this test cell for performing electrochemical measurements to study liquid samples, e.g. electrolyte solutions in lithium-ion battery research.

• Only small sample amounts required
• Robust, user-friendly design
• Air-tight: moisture- and air-sensitive samples can be studied
• Cap with 4 Pt wire electrodes, insulated against each other by glass
• Pt crucible as container and electrode

Typical applications

This test cell can be used for experiments with both a 2-electrode and a 3-electrode configuration. Typical applications are:

• Determination of the conductivity of liquid electrolytes
• Investigation of the electrochemical stability window of electrolytes
• Cyclic voltammetry studies of redox-active samples

Detailed description

The test cell TSC 1600 closed consists of several high-quality building blocks: The gold-plated base unit (= "thermo block") comes with an integrated Pt100 temperature sensor that monitors the temperature very close to the sample, as well as a fixed platinum crucible that serves as sample container and counter electrode. To seal the test cell, a housing made of polyether ether ketone (PEEK) with two o-ring grooves is used which connects the base unit and the cap.

The PEEK cap has an integrated electrode made of a soda-lime glass sleeve bearing 4 separately connectable platinum electrodes, each with a polished front-end. Furthermore, the cap has two inlets that are sealed by plugs by default, but can be used for inserting capillaries or (pseudo-) reference electrodes made of metal wires.
