HTe‾Chem Electrochemistry

Analytical is pleased to offer a new setup for High-Throughput Experimentation for Electrochemistry (HTe‾Chem). This new line of products allows broad electrochemical reactions (such as electrosynthesis, organic electrochemistry, electrophotochemistry, etc.) to be carried out on Analytical Sales standard 24-well minirack platform. Simply speaking, it turns Analytical Sales’ minirack into a high-throughput microscale electrochemical reactor.

Analytical Sales HTe‾Chem platform allows you to accelerate your electrochemistry workflow by permitting multiple simultaneous constant current, constant voltage, and/or electrophotochemical experiments to be run.

Choose between 2 setups; one optimized for constant current, and one optimized for constant voltage.

The constant current setup allows the user to set a precise current, which will be maintained by the power supply throughout the reaction. The voltage will automatically be varied based on the changing electrical conditions as the reaction progresses.

The constant voltage setup allows the user to set a precise voltage, which will be maintained by the power supply throughout the reaction. In this setup, the current will automatically be varied based on the changing electrical conditions as the reaction progresses.

Analytical Sales offers a myriad of  electrode choices which can be used as either cathodes or anodes depending on your experimental needs. If your goal is to determine which electrode(s) work best, we offer an electrode kit.

Analytical Sales HTe‾Chem platform is fully compatible with our 24-LED, 9mm-spacing Lumidox platform, allowing experimentation with electrophotochemical reactions.

Frequently Asked Questions

- Expand Collapse
Does the system include or require a reference electrode for each vial?
Analytical's HTeChem system is a TWO electrode electrochemistry system, with a working and auxiliary electrode (one of which is always the cathode and one the anode) and is not designed for, or require, a reference electrode.
Is the platform compatible with conventional heat plates for temperature-controlled experiments? If not, do you have any suggestions to perform these experiments with the platform?
Again, there is no reason why a user would not be able to place the HTe-Chem reactor on top of a hot plate to run higher-temperature experiments. The limitation here would likely be the circuit board, which would not be recommended for use above 70°C.
Is the platform compatible with running experiments under a nitrogen atmosphere?
In short, yes. There is no reason why the entire setup could not be placed in an inert environment, such as a nitrogen-filled glove box or similar. However there is no way to supply a continuous flow of nitrogen into the vials themselves as the system is sealed once the sealing gaskets and sealing plate are added.
Is the circuit run in series or in parallel? Is it possible to run reactions using alternating polarity?
Both PCBs are designed so that each row is its own separate circuit. The CV board features a parallel circuit, so that if 1 well is bad, it doesn't affect the rest of the wells in that row. The CC board, however, is laid out in a series circuit. Much like a string of old holiday lights, if one well "goes out", the whole row is dead.
What is the platinum purity of the electrodes?
The purity is 99.95%.
I’m having leaking and spalling issues with the graphite electrode for my Electrochemistry Assembly. What can I do?
Graphite is a great choice for an electrode, but it does have its disadvantages. For example, spalling due to oxidation could lead to vapor permeation. Analytical works with a trusted and reputable supplier that specializes in electrodes for our Flow Electrolysis Assembly. To remedy the issue try the following solutions:
  • Use a clear PFA sheet between the vials and the rubber sealing layer.
  • Try running other reactions with a new graphite electrode or a different electrode.
  • Use a virgin graphite electrode that is smooth and non-porous. It is highly discouraged to use pencil graphite as it is an inferior electrode.
