What is Synthetic Urine?

Synthetic urine is a great alternative when normal human pee can’t be used. It contains no toxins, including metabolites that may interfere with the calibration of scientific equipment used for urine testing. This synthetic pee is also shelf-stable, requiring no refrigeration or special handling. It has a shelf life of 3 years in most cases.

Quick Fix Plus 6.3, fake pee can be used in the laboratory for scientific projects without risking lab personnel’s safety. Product testing has never been easier. Quick Fix 6.3 has the same PH and specific gravity as normal human urine. It is perfect for testing the effectiveness of diapers, paper towels, and other products that deal with human body waste.

Easy to Use:

  1. Take it out of the box. 
  2. Heat it in a microwave for 7 to 10 seconds, and you’ll be ready. 

We have even included a heating pad to keep Quick Fix 6.3 Synthetic Urine warm. Each bottle has a temperature strip to identify that your synthetic urine is between 90-100 degrees.

Step 1: Initiate the hand warmer activation process before heating Quick Fix® Plus 6.3 (allow 30-45 minutes for the hand warmer to reach optimal temperature).

Step 2: Shake the Quick Fix® Plus bottle and heat it in the microwave on high for 7-10 seconds. Verify the temperature strip shows a green dot within the range of 94° – 100°F. If the bottle feels warm in your hand but the temperature strip shows no reading, it indicates overheating. Allow it to gradually cool until the temperature strip displays a reading. If the synthetic urine temperature is below 94°F, reheat in the microwave for a few more seconds until the green dot appears on the temperature strip within the 94° – 100°F range.

Step 3: Affix the hand warmer to the back of the bottle opposite the temperature strip using tape or a rubber band. This ensures prolonged heat, maintaining the bottle temperature around 100°F for approximately five hours.

Step 4: If microwaving is not feasible for Quick Fix® Plus 6.3, attach the hand warmer to the bottle at least 1 hour before your test. Shake the bottle both before and after heating, and before pouring into the cup.

Step 5: For unused product, reheat as necessary.
