Collection: Upass Synthetic Urine

Shop the full Upass synthetic urine lineup direct from Safeguard Labs: the 3 oz single kit, the 2-pack and 3-pack bundles, and kits bundled with Hot Sacks hand warmers for longer heat.

What sets Upass apart is consistency. Upass is independently lab tested, and every batch is quality-checked in-house against the same specification before release, so bottle one and bottle one thousand behave identically. Safeguard Labs has manufactured Upass continuously since 2009, 17+ years, with millions of kits sold.

Every Upass 3 oz bottle comes premixed, with no powders to measure, and includes an air-activated hand warmer and a temperature strip to bring the sample into the 90 to 100 degree F working range. Sealed bottles carry a two-year shelf life, with the expiration date printed on the box next to the lot number.

Upass is sold for lawful uses: calibrating and validating urinalysis equipment and dipstick panels, scientific research and product testing, medical and laboratory education, demonstrations, and adult novelty use. Buyers are responsible for compliance with applicable laws.
