Yes, so far as I can tell. The documentation doesn't say one way or another, but in the cleaning instructions it's basically the exact same care instructions as with other ADA diffusers.
As far as getting a picture, I'll see if I can manage one in the next couple of days.
I should also point out that the documentation that comes with this says it's not suitable for aquarium use because, to quote, "it gives off CO2 in air as well as water". No further explanation is given or expounded upon. After using it for the past two weeks, though, I can honestly say it seems to work just fine in an aquarium setting. No bubbles are given off anywhere other than at the diffuser ball, the bubbles produced are as fine as those from other ADA diffusers, and it easily keeps my CO2 levels where I want them. I only run about 1 bps and I'm honestly not sure the surface area of the diffuser is enough to handle a whole lot more than that... 2 bps I've tried with no problems, but more than that might be iffy. I'm also using it in a fairly shallow aquarium, only 12" tall (less, after substracting space taken up by substrate); that might make a difference as well.
But as far as I can see, if you've got a small tank running only modest amounts of CO2, this is a great option.
Can you get CO2 Ball Glass diffusor?
