Urine Diluent – Synthetic Diluent for Urine Samples, pH 6.6 BZ502
Product Code: BZ502
Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L
Custom Bulk Quantities Available
Product Overview
Biochemazone Urine Diluent BZ502 is a sterile, ready-to-use synthetic formulation at pH 6.6 that closely mimics the physical, biochemical and rheological properties of human urine. It is designed for diluting, processing and standardizing urine samples: because the diluent has the ionic strength, pH and solute content of urine, a sample diluted in it stays in a urine-like environment, which water or saline would not give.
BZ502 is used to dilute concentrated urine samples for microbiological analysis and quantitative culture, in antibiotic susceptibility work and CFU enumeration, in pharmaceutical research on drug delivery and compound excretion, and wherever a protocol calls for reproducible, standardized test conditions. The standard formulation contains the electrolytes sodium, potassium, calcium, chloride, phosphates and bicarbonate, with urea and creatinine.
BZ502 is supplied not stabilized – without preservative, so that it does not inhibit the organisms in a sample – with a 6-month shelf life unopened; an antimicrobial (stabilized) version with a 1-year shelf life is available on request for work that does not involve culture. Buffer strength, solute concentration and composition can be customized. This simulated fluid is for scientific research and in vitro use only. For a urine medium that supports growth see Artificial Urine Medium for Growing Urological Pathogens (BZ103).

Frequently Asked Questions
Why dilute urine in a urine diluent and not in water?
Water or saline changes the ionic strength, pH and solute content around the organisms or analytes in the sample. A diluent with the composition of urine keeps the diluted sample in the same environment, so counts and measurements stay comparable.
How long does the diluent keep?
Unopened, the not-stabilized diluent has a 6-month shelf life at 2–30 °C. An antimicrobial (stabilized) version with a 1-year shelf life is available on request, for work that does not involve culture.
