Making your own hydrometer sample jars?

[Newts]

Hey all,

Anyone done this before? I put my plastic one in a hot sink and it melted away. No one sells them locally and I know they wouldn't be hard to make.

Won't put a hydrometer in my brew - wouldn't risk an infection. Just fishing for ideas.

Cheers,

Newts

You could make one... Or lash out ten bucks or so at pretty much any home brew shop...
You mean something like this

Alternatively, consider buying yourself a refractometer.

Once used, you won't go back to hydrometers, nor waste precious beer on tests.

... But what about my taste samples warra?

I use a refractometer hot side and still use my hydrometer cold side, mostly so I get a taste of it, sure, I might only take one or two through the whole cycle, but I like having those sips

I just pour some beer into a shot glass to take my cold side samples, lets me get enough for the refrac and a little sip to see how it's progressing, unless it's a bitter, then I'm likely to pour a pint, bloody love bitter straight from the fermentor.

Does the diameter of the hydrometer sample jar even make a difference to the reading? And what about the height of the fluid? I'm pretty sure they don't - which would mean that any old jar, so long as its deep enough to hold enough liquid to prevent the hydrometer touching the bottom, should do the trick - though one that's tall and thin is obviously best, as then you can minimise the sample size.

does a refractometer always turn away from you when you go to read it

YES! The hydrometer is always facing the wrong way!
I got a 250ml cylinder from a hospitality place works well. As Tim said as long as the container is taller than the jar you should be fine.
I recently got a hydrometer jar from G&G it's 2 piece and allows you to fill then drop in the hydrometer so the liquid is level with the top of the jar. The base catches the over flow.

I also have a refractometer and use it all the way through the brew process and only really use the hydrometer for OG and FG.

No, unless the diameter is so small that the hydrometer can't fit.

I have had one of those that Bridges pictured in the second post for years.
100ml works perfectly for me, has a decent stand and doesn't topple.

You could make your own jars, use refractometer.... or use the old school method and see 'whether the liquor beareth an egg'. I'll have to try that sometime myself.

YES! ******* of a thing

Some hydrometers come as a retail pack in a plastic sleeve and if necessary you can use this sleeve to grab a sample for a hydro test.
They have a plastic push in bung in each end that wont be entirely watertight but will be good enough for your SG reading and a quick sip or two of the precious wort.
Unfortunately thay are a very low quality plastic and are generally scratched on the outside if used for general storage.

I got a big arsed glass one from the Keg King site to make up the free freight deal. It is a great test tube but holds "far too much wort"
Maybe a smaller one from the pics above would be good.

I often wish you could buy a smaller hydrometer purposely built with a larger scale for only measuring FG of wort and have a calibration card that has some space between the lines and the increments that are dead easy to read accurately...for example only reading from say 1.020 down to 1.000

You have to turn around when you spin your hydrometer to confuse it. Then after a bit turn around and it'll be facing the right way every time.




results may vary...

Just buy another hydrometer. It will come with another sample jar. I have broken 4 so far. The jar should outlive the hydrometer.

I also like having sips from my hydrometer cylinders. Y'know, I'm buggered if I can figure out why I always end up with short-filled kegs.......

Nope, but it certainly makes a difference to the "sips"

My first hydrometer was from Brigalow, bought at Kmart for 8 bucks from memory. Was the best I ever had. It was really short (about 10cm) and only went up to 1.040, and obviously the sample tube was really short as well.
Perfect for those who use a refractometer on the hotside.

sadly they don't sell it anymore.

 

[Newts]

Yeah, I did just buy another hydrometer and didn't realise it didn't come with a sample jar. Have 4 hydrometers and a refractometer so def don't need any more measuring devices. I prefer the hydrometer over refrac personally hence why I wanted a new container. Guess I should just order one with my next home brew order.

does not seem to be in the range now at G & G

Make one out of a bit of clear plastic tubing.
