I'm very tempted to get a Ergotron LX arm for my Hazro 27" monitor, but can somebody who owns one (or knows about these things) give me an opinion if it will be suitable to grip a solid glass desk. The glass is quite thick so it should hold the weight, but I'm not sure if there will be enough friction for the grip?

Personally I wouldn't be too keen on trying, as to get the stand secure enough, you'll have to tighten it quite a lot, which could cause the glass to crack.
yes, you cannot use a clamper for glass desks. tempered or non tempered glass.
I guess you mean this one?

but have you considered wall mounting:

double check on the weights, dnt worry about MX being 24", just verify your hazro within weight restriction of LX and MX. if your Hazro is glass it's going to be heavy I guess

Trouble with tempered glass is its lovely and nice while its in perfect condition. A single chip can in effect cause the entire block/table to break, however, break safely into chunks.
You can do some reading about the manufacturing process here:
http://en.wikipedia.org/wiki/Toughened_glass
its all about the stress and how you stress the surface. Monitor stand would distribute the weight better and will be stable, while a stand like the LX will have a small gripper that focuses the stress at a very small position and also the arm is constantly straining the mount because it is suspended, if you can imagine.
think about the pin
http://en.wikipedia.org/wiki/Pin
if you enlarge the needle point it becomes harder to penetrate surface, but the reason why pins work is because stress is focused on a tiny area,
Monitors are light, agreed, but I wouldn't want to place (in your case 8.5kg) suspended from glass.
padded?, same problem. but perhaps, if you have 2 10mm thick plank of wood, each of 300~400mm length and about 150~200mm width, you can use these to try to to distribute the weight to a larger area, radiating away from the centre of the clamp
\/\/\/\/\/ --> top teeth of clamp
========= -> 10 mm thick plank of wood
---------------- -> glass table
========= -> 10 mm thick plank of wood
\/\/\/\/\/ --->bottom teeth of clamp
you get the idea, not sure but using 2 A4 polycarbonate sheets instead of the wood would look better and may do the trick, there about 7 quid on auction sites ...
Hope this helps, but I would stick with a stand
