Lab and Clinical Diagnostics

The Issue

Laboratories and hospitals utilize high-tech and precise equipment to analyze and diagnose patients. These high-throughput machines are very precise and require consistent care to maintain their accuracy. One element of care is consistent decontamination to prevent false readings caused by pathogens such as bacteria or viruses.

With some products, this decontamination sequence can cause a lot of downtime, precluding clinical analyzers and other machinery from running valuable tests. This will delay results and increase cost of testing.


SMT’s ultra-pure ClO effectively minimizes downtime for diagnostic equipment such as chemistry, immunoassay, and hematology analyzers by decontaminating and stripping organic matter from internal fluidic lines. Because ClO has no ionic charge, it quickly rinses from the system, usually in a single flush. Chlorine dioxide is also very effective at removing bioslime, reducing recontamination and increasing time between decon cycles.

Additionally, a neutral pH ensures the highest levels of material compatibility, minimizing effect on sensitive equipment. For years, SMT has provided effective products and solutions to companies such as Roche Diagnostics, Ventana, Siemens Healthcare Diagnostics, and Beckman Coulter.

Field Trial: Decontamination of USP water purification systems and distribution loop


USP Water System Distribution Loop
The water system and distribution loop included two 125-gallon water storage tanks plumbed in parallel. The tanks store RO/DI water that feeds the distribution loop. A system diagram is included in Figure 1. The storage tanks were full of water at the beginning of the decontamination process. Prior to starting the procedure, the DI tanks were removed from the system. Chlorine dioxide was generated directly in the storage tanks. During the generation period, water was recirculated through the loop, returning to the tanks. No make-up water from the RO unit was added to the tanks during the generation and recirculation period, and power to the in-line UV lights was disconnected.
