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. 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 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.

Take it out of the box. 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 Synthetic Urine warm. Each bottle includes a temperature strip to identify that your synthetic urine is between 90-100 degrees.

  1. Activate the hand warmer before heating Quick Fix® Plus.
  2. Shake the Quick Fix® Plus bottle and microwave on high for 7-10 seconds. The temperature strip should display a green dot in a range of 94° – 100°F. The synthetic urine is overheated if the bottle feels warm in your hand but does not show a reading on the temperature strip. Let it cool down gradually until you see a green reading on the temperature strip. If the synthetic urine temperature is below 94°, heat again in the microwave for a few more seconds until you see the green dot on the temperature strip between 94° – 100°F.
  3. Attach the hand warmer with tape or a rubber band to the back of the bottle opposite the temperature strip. This will provide prolonged heat, keeping the bottle temperature near 100°F for approximately five hours.
  4. If you can’t microwave the Quick Fix® Plus, attach the hand warmer to the bottle at least 1 hour before use. Shake the bottle before and after heating and before use. **If your product remains unused, it can be reheated repeatedly thanks to Spectrum Labs patented biocide.
  5. Always check your batch number in the batch validation tool on our home page before using the product. Batch numbers are printed on the bottle. Expired products will be exchanged for retail customers at no charge.
