Why high level disinfection for ultrasound probes?

What is trophon2?

Distributed by GE Healthcare, trophon2 is an automated high level disinfection for endocavitary probes. Smart Protection - trophon2 contributes to protect patients, staff and the environment by helping to reduce risk10.


trophon2 contributes to reduce the risk of ultrasound-related cross-infection in your facility

  • Offers effective bactericidal, fungicidal and virucidal protection11
  • Provides high-level disinfection, consistent and reproducible. Be ensured that you are protecting your patients while adhering to the high-level disinfection guidelines and standards of the ultrasound probe12,13


trophon2 helps to prevent exposure to hazardous chemicals, fumes and spills  

  • Sealed system with automatic door locking and sealed disinfectant cartridge
  • Enclosed chemical indicator. No manual test strips


trophon2 generates environmentally friendly by-products for safe and easy disposal

  • Recyclable disinfectant cartridges and greater than 70% recyclable components
  • Patented system breaks down the disinfectant primarily into oxygen and water with a small discharge tray for easy disposal of by-products

“Easier for users, simpler for the biomedical service”

Smart Flexibility

trophon2 streamlines set-up, can be customised to your workflow and has extensive probe compatibility to help improve efficiency.


Can be placed at point of care and set up in a wide range of locations, on a bench, on a mobile cart or on a wall mount. There’s no need for sink/plumbing or special ventilation and no open chemicals that could spill.

Whisper quiet disinfection cycle, ideal for use at point of care.

Compact size – fits in examination rooms.


Configure trophon2 to your unique needs so it is always ready when you are.

Sleep timer: Enters power-saving mode when not in use. Adjust in hourly increments or there’s an option to turn off.

Daily warm up: Adjustable ‘wake up’ times for each day, trophon2 is ready to start when your day begins.


Over 1000 probes have been validated for use with trophon2 by all ultrasound probe manufacturers14.

Extensive testing: In conjunction with probe manufacturers who give final approval.

>> Easy to check if your probe is compatible for use with trophon2

Smart Traceability

AcuTrace™ simplifies the creation of accurate digital records, all stored on your trophon2 to help increase audit-readiness.

AcuTrace™ PLUS delivers an upgradable option to seamlessly connect trophon2 to your hospital information system to simplify data access.
