QF = Quick Fix synthetic urine. Its a 2 oz bottle of premixed laboratory urine that you use instead of your own dirty urine. It comes with a temperature strip already affixed to the bottle so you can be sure to get the sample up to proper temp (90-100 dg). A heatpack is supplied with the QF for maintaining heat for over six hours.

For more info on the QF, use the search feature here, keying in on Quick Fix synthetic urine.

Hope that helps
