TWL PLANODE1X4 Platinized Titanium Anode 1"x4"

This is actually platinum coated titanium. Beware because there are fakes out there but this is the real deal. Used for chlorate anode. 5v 40amp power supply and ran it for months. No breakdown whatsoever.

These have real platinum coating on them. I bought two of them, both withstood so harsh electrolysis conditions that if the coating was from another metal it would be definitely gone by now.

This has helped me with my 4th and Nye science experiments.

I purchased 2 of these. I tested both, and both of them not only sparked bright white on the uncovered titanium bar, but also caused 12% H2O2 to bubble quite nicely. A close visual examination shows complete coverage indicative of electroplating. It also showed just enough surface blemishes (that cleaned off) that I strongly advise cleaning it according to your needs before use, as whether they came from manufacturing or shipping, you probably don't want the unknown impurities in your cell.BE AWARE: This is obviously not a precision manufactured, pro lab grade item, carefully calibrated with unbeatable QC. The fact that its being sold on amazon at this price should give that away. That being said, it is what it says it is. If you use it conservatively at a low amp/volt setting it should last you quite a long while at a heck of a price

This is definitely platinized. It has been holding quite up well in a saturated NaCl solution with high current densities. Would buy again.

The folks who have given this electrode a poor rating have done so on the basis of a general confusion as to WHAT constitutes an "Anode" or "Cathode". I don't care what the Chinese or even the various chemistry associations have to say about it ... We need to adopt the common sense definition to avoid that confusion. In the "Practical", common sense definition, THE ANODE is the electrode to which the positive voltage lead is connected ( NOT the one to which positive particles are "Attracted" ). THE CATHODE is the electrode to which the negative or ground lead is attached ( NOT the one to which negative particles are attracted ). SO; by the above definition, In any electrolytic or electroplating circuit, the Anode will be dissolved and the cathode will be unaffected ( or plated onto ) and if you want to keep your Platinum electrode intact, attach it to the NEGATIVE lead.

I've had two of these in a chlorate cell for almost three weeks at 4.7V with barely any drop in efficiency. While it's certainly possible to destroy these through negligence, treated properly they seem a great bargain for the price. Keep your temperature high to avoid free chlorine, monitor pH closely and these should last you a while.

The busbar weld is not good but they are certainly platinized. I used these with a WELDER at a ridiculously high amperage to see how well it would hold up and you can look at the picture and judge for yourself. The cathode on the right is plain titanium.
