Is it possible?

Is it possible to dehydrate urine? I am clean right now, but I'm unemployed and looking for a job. I would like to start partaking again, and I would like to be able to have a clean supply on hand. Since I'm unemployed, I can't afford to buy a clean supply, otherwise I would! I've read that all you have to do is pee into a glass container and let the liquid evaporate, but I'm pretty sure that bacteria would form before evaporation was completed. Would heat, say from lights or even an oven, alter the sample? Any info would be greatly appreciated! Stay safe, everyone!

I'm pretty sure I heard that you can freeze it, and that is the only way to keep it preserved.
