Trial jar

So I managed to get my vinegar and sacrificial run done on the T500 reflux at the weekend, had good fun trying to get used to the water flow and trying the new power control on the boiler.
When it had finished I decided to see what the abv was. Filled the trial jar, added the alcoholometer and then realised that too much of it sticks out for me to get a measurement, it was at 90 and I couldn't fill the jar any higher. Ended up tipping nearly 700ml into a wine bottle so I could measure it
Anyone got a recommendation for a trial jar which is bigger than my 100ml one. Or of course a smaller alcoholometer which would fit in my existing jar?

I suffered with the same issues and made a parrot out of 22mm copper pipe and a few reducers and a bit of 8mm to connect it all together. Make it as small as possible to avoid smearing when using it inline. I do also have a rather large glass trial jar and a refractometer from China (only goes up to 80% but good for watering down)

Does it have to be graduated/marked ? Cos I've seen various sizes of test jars, both marked and unmarked when digging around lab glass on eBay.
I know the ones aimed at home brew tend to be 100ml ones, as that's the size of many hydrometer/alcometer, but I've definitely seen other sizes there........

The issue isn't always the jar.
Get the right scale hydrometer. There was a set of 3 on ebay.
Or use a wide scale hydrometer, which will sit properly and is very accurate.
Better still, wash the jar, pop it in the back of a dusty cupboard and buy a refractometer. Much easier, cleaner and quicker. You won't change back.

That reminds me, I've actually got one
Thanks all for the advice

The glass graduated test cylinders I have go to 250 ml. They work great for me.

Which is why it's worth digging around. I've seen the big commercial ones used with the expensive, narrow range/high accuracy ones. Those jars go to about 2 litres........
