Platinum Electrode Holder with 10x15 mm Platinum Sheet and PTFE Body

We are designing an electrochemical device for use at 200 degrees C, and I was wondering if your electrode holders are thermally stable (e.g., are there any resins or glues that would not be stable at high temperatures).

Dear Customer,

Our Platinum Electrode Holder is thermally stable at 200°C because it features an internal connection made entirely of platinum wire, ensuring high-temperature resistance.

Thanks,

Can this electrode holder be fully immersed in acidic electrolyte?

Dear Customer,

Yes, the electrode holder is suitable for use within a standard pH range of 1 to 12.

How was the welding done and is the welded junction still corrosion- resistant if the junction contacts the electrolyte?

Dear Customer,

Below is an image showing the internal structure of the Platinum Electrode Holder. The welded junction is reinforced with epoxy resin and protected by a PTFE layer for corrosion resistance. However, prolonged immersion in electrolyte can degrade the epoxy, leading to potential leakage. We recommend keeping areas above the platinum sheet out of the solution to maintain durability.

In one answer you said the wire inside the PTFE shell is platinum and silver. Which part is silver and which part is platinum? Is the wire in contact with the platinum holding plate platinum? Is the silver part accessible to the electrolyte?

Dear Customer,

The platinum sheet is welded to a short section of platinum wire, which is then connected to a silver wire. Additionally, in normal usage, this product is not designed to be fully immersed in the solution.

Thanks,

Have this a smaller one? Like 5mm wide of Pt Sheet?

Dear Customer,
We can custom-make the product for you with a minimum quantity of 5 units. If this quantity works for you, please write back to us at support@stonylab.com with more specific details about your requirements. Once we have this information, we will provide you with a quote accordingly.
Thank you for considering StonyLab.
Best regards,

Is the wire within the PTFE body of the holder also platinum? Or only the sheet at the end?

Dear Customer,
The marterial inside the PTFE body is platinum wire and silver wire.

How much current can be passed through the wire inside the PTFE?

Dear Customer,
1A can be passed.
