Peezy Midstream FAQ

How does Peezy Midstream capture a clean-catch sample?

The first flush of urine will wash natural bacteria and other debris out of the urethra and off the skin and into the sample. Peezy Midstream rejects the first 10-20ml of first-flush into the toilet; this moisture will prompt a compressed cellulose sponge to expand and block the outlet. Midstream urine is diverted into the appropriate collection tube. Once the tube is full, a vacuum is created to avoid dilution and excess urine is diverted into the toilet. Peezy Midstream is engineered to manage urine flows between 10ml to 40ml per second (min / max*) and cannot overflow.
