what do you use to preserve urine & where can i buy it?

if you are buying and using you do not need to "preserve" urine (just store in a cool dark place) ... but if you really feel you need to ... you can use sodium benzoate but methyl paraben would be better

if you're looking for something to slow evaporation ... I'd suggest glycerine ... roughly four ounces to a gallon

*don't mix glycol with urines (suggestion of preference)

how come no glycol with urine? i have been adding it when it gets cold, just so the eye dropper will pull.

does the glycol "change" urine?

teach me something would ya.

After the season, put it in the freeer...

It will not change it one bit.. a Doctor friend of mine told me that they freeze urine samples all the time, and they can still put the DNA or cells that they need to study without any problem.....

Just don't put in a jug labeled 'apple juice'.

i have some fresh stuff and need to preserve it

ol' bulletbox pretty much hit the nail square on the head for storage ... that would be best ... followed by just keeping it in a cool dark place (if it's good, clean urine to begin with it'll get better with natural aging anyhow, probably another 'me" preference )

not sure who told ya that you need to preserve urine or why you are so heck bent on thinkin' you need to ... 'cause, honestly you really don't need to! ... seems to me you might be overthinking something that is so simplistic

ub - no real learnin' to be passed on, just my preference ... you and many others use or have used glycol in urine as an antifreeze ... to add and use, most likely you'll have no concern ... but for storage I think it's best not to have it mixed in ... time, urine and glycol can go wrong

ok i just have so much i was going to try to sell it
it`s fine fresh then?

Its fine fresh as long as it is strained well of food particles. It is food particles that will spoil and make the urine smell like a sewer. Food particle free urines will last for years stored in a cool dark place. When storing for extended periods of time it is best to do so is glass bottles as plastic containers being porous allow the amonia content to escape resulting in a flat smelling urine. If one really thinks they need a preservative one can add a cup of plain pickling salt per gallon of urine. This will not from my experience compromise the value of a urine as the urine already has a natural salt content. A cup of pickling salt also serves as an anti-freeze down to moderately cold temperatures. Asa

asa, is adding glycerin to the urine a good idea to keep it from evaporating on your sets quickly a good idea?

I have urine that has been in plastic for 12 years and its still very potent. I think it depends on the plastic it is stored in. I would never store urine in a gallon milk jug type of plastic, but I wouldn't hesitate to store it in the plastic gallon jugs sold by Sterling Fur, and probably others.

This urine is some that dad put up before he passed away back in 1997, and its still very good.

Now that is some good stuff Paul!

I collect my own coyote urine from penned yotes as i also sell them to the live market. I collect the urine everyday from the drain board setup and strain it through clean painters rags 2-3 times so it is clean as can be and it seems to hold over from season to season very well in the fridge in my shed. I do add about 4 ounces of glycerine to a quart of the pee but this is to keep it from freezing and turning into slush while trapping in the winter time. Really has nothing to do with preserving it...not for me anyway.

Definitely a difference between soft and hard plastics, the hard being less porous and more similar to glass. Asa

As Asa states if it is clean it will last indefinitely. If it contains alot of organic material these will become contaminates over time and compromise the urine completely. How bad it becomes is relative to how contaminated it is with food particles, blood and feces.

When it is real bad even straining wont help alot. Only pasteurization will stop the break down if caught early enough.

I only use glycerine in the Winter to keep from freezing. In warmer weather I try to soak the urine into something natural at the set like moss, rotten wood, etc as it will last a long time that way, even when dried out it will still give off odor. Asa

J...."What brand of apple juice did you buy honey? It tastes funny."

Reply from the laundry room..."It was on sale...a two for one deal. I think it was Dobbins brand or something."

i just throw it in the freezer till fall then set it out and use as needed....

its [Please excuse my language... I'm an idiot].. it ain't going bad for awhile...lol

Nothing...if its good it stays good (for years) Like paul said, i have urine that I first collected when starting up. been sitting in a hot barn for many moons and when you twist off the cap it will roll your eyes back in your head. Wouldn't hesitate on using it.

If its junk, then you better throw it away...or if they are selling junk it has been messed with (like above) with sodium benz/etc.

adding Gylcol in the winter is sometimes done to keep it from freezing at the set and slows the evaporation rate in the heat of summer. which is okay and doesn't hurt the urine aslong as the Glycol hasn't been compromised.

Good, clean, clear urine free of organic material and stored airtight in glass should last practically forever.

This post needs to be put into the archives when it dies...ALOT of good info in here from some really experienced pee men
