Random Urine Collection for Urinalysis. Random urine samples are used for urinalysis, which can screen and diagnose metabolic disorders and urinary tract infections. Your doctor may order urinalysis to determine, for example, the cause of bloody urine, abdominal pains or burning sensations associated with urination.
1 Place potato slices into a large bowl of cold water as you slice. 2  Drain, and rinse, then refill the bowl with water, and add the salt. 3  Let the potatoes soak in the salty water for at least 30 minutes. 4  Drain, then rinse and drain again. 5  Heat oil in a deep-fryer to 365 degrees F (185 degrees C).
I don't know how exactly you fried them, but normally, the second time you deep-fry them is to get them crisp. Make sure you deep-fry them at a hot temperature (180-190Â°C or 355-375Â°F). If they aren't crisp enough for you after two minutes, leave them in for another minute and check again. Another thing I've heard a lot (but without actual proof) is that you best not rinse the potatoes after you've cut them.
