They're not that robust. If you drop it and break the tube or even if you use the wrong cleaning agent in the tube and etch it, the thing is buggered. In the one I have the tube cannot be replaced so that's the end of it. One advantage is that you know it will cost $4k to replace so you tend to be careful.
The most recent model is a modular design and the tube unit can be bought as a repair part but I believe it's over $1k.
BTW I found a new trick up its sleeve yesterday: if I set the unit to ABV it reads accurately enough to do alcohol in wine by the "method of differences", using an Atago Pal -Tea refractomoter for the second reading.
I used the algorithm ABV = (A + 2.75 R) / 2 where A is the reading on the DMA35 and R is the reading on the refractometer.
