Hanna Titrator HI 901-01

Anyone using this?

What advantage does it have over the

Hanna Instruments HI 84100-01 Mini Titration System for Free and Total Sulfur Dioxide Measurements in Wine Analysis

and the Hanna Instruments HI 84102 Mini Titration System for Total Acidity in Wine

(Both of which I have already)

Will it do VA measurements?

Thanks!

It is our “go-to” piece of labware and we rely upon it heavily.

Never used the other machines you mention, but one major difference is that the 901 has only piston pumps. I recall a few people on this board who were not happy with all the calibration and/or pump problems with the dedicated titration peristaltic pumps. If you’re feeling flush, I would say spring for an extra pump so you can have 2 different titrants always loaded.

It will titrate va distillations, and there is a must nitrogen method for ‘fan’ that we use a lot. There is also an ‘rs’ method but I have never put much stock in it (think it’s based on the layne method?) so I use and the pill for rs checks.

Solid piece of equipment, but it is really just a simple machine that does acid-base and potentiometric titrations. It is still subject to GIGO, so poor calibration, sample prep or distillation will make it a fancy paperweight.

So it will do VA measurements via the machine , and can we replace our cash still if we have it?

It only titrates, so you won’t replace your cash still. You still need to do the distillation. It titrates the distillate.

I had heard there are automated micro still machine that could do VA measurement in wine… Any idea who makes it?
