TWL PLANODE2X3 Platinized Titanium Anode 2"x3"

In a field FULL of counterfeit and downright deceitful descriptions claiming platinized titanium anodes, you can stop here and look no further. These are absolutely what you are looking for in a platinum anode. When you need a non-reactive anode for chlorate cells or other corrosive electrolysis procedures, platinum is the way to go. So just to be sure, I performed several tests to confirm it’s platinum, including the quick and easy H2O2 check, which shows all I needed to know (but honestly, you can tell just by looking that it is plated with true platinum). That said, there’s more to it than just the platinum plate. Like, how rugged is it? Will it stand up to a particularly heavy current? How long? So I wanted to wait a while before leaving this review. As, only time will tell if I can depend on this purchase. Which, I am happy to say, I can give a five star review. I’ve been running this anode in a chlorate cell a bit over 3 months now, 7V @ 4A in a saturated KCl electrolyte and titanium cathode. This produced plenty of KClO3 at a decent rate but more importantly, I have noticed zero corrosion on the anode. It looks just as good as the day I received it. I know that’s not pushing it hard and I’m sure I could easily take it up higher, push it harder, but I’m in no rush and that seems to be the sweet spot for my setup. So what else can I say? It does its job, it’s exactly as what it is described, a decent sized platinized titanium anode. Forget MMO or messing with PbO2, this is all you need for small scale electrolysis of anything corrosive.

The item arrived on schedule, and it seems to be a good quality electrode. It should work well for electroplating a new finish on small pieces of jewelry.

Excellent anti corrosive properties

These might have once been real, but it seems that there are fakes being sent out now... The one I received was made from stainless, and had no catalytic activity.. Even the dimensions were wrong.

I bought this anode and for my purposes which is a wide range of Electrochemistry projects it would tarnish so I plated it in Lead Dioxide and it's far superior now!

Platinum coated titanium. Ran chloride cell for many months. 5v at 40amps. Held up like a champ. This is the real deal. Bought a fake from another supplier and dissolved completely in less than a half hour.

These anodes work quite well even at high amperage. I have ran as much as 20 amps threw these for as long as several weeks. After several runs like that they will start to break down. But hey they are not designed for that. What I am getting at is they work well even when abused. If you use them properly they should last a long time.

Just sitting. Hope to get my electroplating tanks working someday soon. I could anodize Ti. but was hoping for nickel etc.

There are a lot of fake platinized Titanium anodes out there that completely destroy your chemistry experiments, but the ones sold here are the real thing.

Its totally real, works as a catalyst for H2O2

I estimated area at around 32 cm2, running it at 8a/4.4v so 250ma/cm2 in Perch cell for 144 hours and it performed very well no discoloration or signs of degradation. I can't speak for durability, pt layer thickness ect. and It's my only mesh anode but it does what it's supposed to do.

This electrode is genuine platinum and is fairly nice, it works quite well and stands up in a saltwater electrolysis cell. I would however, not recommend that you use it as a cathode instead. I had mine running in a saltwater cell for about a week and a half. And it stood up great during that time, no significant damage at all. But during that time I also had an MMO anode delivered and wanted to use that instead. The platinum electrode was a good size to use as a cathode, so I decided to do that. But for some reason, the coating on the part that attaches to the platinum mesh started falling off within a day of me switching it. When I switched it back to being the anode it continued to fall off and the solution started attacking the titanium underneath, corroding it heavily and contaminating the solution with a white precipitate. I had to take it out of solution and use the other anode instead. I was able to clean it off, sanded it down, and then blasted it with a torch to create an oxide layer. And I tried it again in the cell and it seemed to stop corroding. But either way, not wanting to destroy it, I had to take it out. I do want to stress though that the platinum coating is great, and had no damage whatsoever throughout all this. But for whatever reason, the coating that they use on the rest of it seems to be pretty prone to damage. And if it gets damaged in corrosive conditions, it could potentially destroy the whole electrode. Either way, I'd recommend this electrode. Especially considering how hard it is to find genuine platinum electrodes that aren't fake. But just be very careful with it, and do not use it as a cathode.

As far as I can tell these are the first electrodes I’ve bought that actually have a platinum coating. Incorrect (smaller) size sent when I repurchased.
