Collection: Lab-Grade Synthetic Urine | Negative Control Samples

Laboratories, universities, and device manufacturers use Upass as a stable negative control sample for urinalysis workflows: dipstick validation, reagent QC, instrument calibration, and hands-on training. Each batch is tested for pH, specific gravity, urea, and creatinine before release, and the batch number printed on every box gives your QA documentation full traceability.

Because Upass is premixed and sealed with a 2-year shelf life, it eliminates the variability and biohazard handling of pooled human samples. Standing orders and case quantities are available through our wholesale program, or order single kits and multi-packs below with same-day dispatch.
