Process sterilizer MediPlas

ozonehydrogen peroxydein-line

Overview
MediPlas delivers on-demand, in‑situ sterilization by generating reactive oxygen and nitrogen species (RONS) that inactivate bacteria, viruses, fungi and spores on diverse surfaces. The low‑temperature DBD process is suitable for plastics, electronics and sensitive medical devices and offers a faster, chemical‑free alternative to autoclaving and ethylene oxide.

Principle
The system consists of two main components: a DBD reactor and an electronic driver. The reactor creates RONS through dielectric barrier discharge; the driver controls power and timing. RONS composition and concentration depend on multiple parameters:

• Type and humidity of the input gas
• Temperature inside the reaction chamber
• Driver power and timing settings

The system can be tuned in real time to obtain a tailored reactive gas composition without hardware changes or added chemicals.

Applications
Closed-loop systems (Cleaning in Place, CIP)
Continuous circulation of reactive gases enables sterilization of assemblies without disassembly; reactive agents are removed or neutralized after the cycle. Suitable for integrated medical systems requiring repeated in situ decontamination.

Batch setups
Items are placed in a sealed chamber that the reactor fills with reactive gases to ensure comprehensive surface exposure. Low-temperature operation makes the method appropriate for endoscopes, wound dressings, stents and other heat‑sensitive devices; cycles are faster and do not require added chemicals.

Plasma-activated water (PAW)
By ionizing the air or a specific gas over water, MediPlas produces PAW containing species such as ozone (O3), hydrogen peroxide (H2O2) and nitrogen oxides (NOx). PAW is used for microbial control in medical/dental sterilization and related hygiene applications.

Benefits

• On‑demand generation: reactive species produced in situ, avoiding hazardous chemical storage
• Chemical‑free, low‑temperature process suitable for heat‑sensitive materials
• Reduced cycle times and faster turnaround compared with EtO or long aeration autoclave cycles
• Adaptable: real‑time tuning of gas composition without hardware changes

Evaluation Kit
The MediPlas Evaluation Kit equips developers and technical teams with hardware, setup instructions, sample code and real‑time data access to:

• Explore core MediPlas functionalities
• Simulate real‑world use cases in a controlled environment
• Accelerate integration and validation

Documentation and resources
User guide, reactor and driver datasheets, evaluation kit datasheet and technical presentations are provided to support testing, integration and validation. Documentation includes microbiological contamination analysis and integration notes. No URLs are provided here.

Disclaimer
The term "sterilization" here refers to the system's microbial inactivation capability. Achieving complete sterilization depends on boundary conditions (exposure time, reactive species concentration, environment and validation protocols). Users must validate settings against applicable standards and regulatory requirements.
