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, which means their analyzers aren’t running tests. This delays results and increases costs of testing.


SMT’s ultra-pure ClO  effectively minimizes downtown 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 the time between decon cycles. Additionally, a neutral pH ensures the highest compatibility, minimizing effect on sensitive equipment. SMT has provided 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.
