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).
Turn the deep fryer on and heat the oil to 350 degrees F. Donât let it get too much warmer: The BCCDC states that frying oils should not exceed 355 degrees F. If your deep fryer has a frying basket, remove it and place a handful of cut potatoes into the basket. Otherwise, place sliced potatoes into a metal skimmer. Slowly lower the basket or skimmer into the hot oil. Be sure to use an oven mitt to protect yourself from the hot oil.
