Tristel ULT

Tristel ULT is a high-level disinfectant foam intended to disinfect cleaned, reusable, non-lumened ultrasound probes. Tristel ULT is intended to be used by qualified healthcare personnel. Tristel ULT does not sterilize.


Tristel ULT is a high level disinfectant foam for reprocessing ultrasound probes.

Tristel ULT can be used to high level disinfect endocavity transvaginal and transrectal probes, and skin surface transducers that may contact non-intact skin during use.

Tristel ULT is classified as a Class II Medical Device under the Canadian Medical Device Regulations SOR/98-282

Tristel ULT is based on Tristel’s proprietary chlorine dioxide (ClO2) chemistry. Tristel ULT generates chlorine dioxide foam from two “precursor” solutions (Base Solution and Activator Solution), which are packaged separately within two individual containers and secured together within a single dispenser apparatus known as the “pump”.

Chlorine dioxide is an oxidizing biocide. It deactivates microorganisms by attacking and penetrating their cell wall, disrupting the transport of nutrients across the cell wall by inhibiting protein synthesis.

As this action occurs regardless of the metabolic state of the organism, oxidizing biocides are effective against dormant organisms and spores.


3T is a fully featured, cloud-based device reprocessing compliance platform.

3T combines an intuitive mobile app for use at the point of care with an interactive web portal. It provides users with a valuable tool for record and traceability of device reprocessing.

3T guides users through the device reprocessing steps, tracking each event and making the record available to view in real-time.
Aggregated data from device reprocessing events are securely stored and can be found across interactive dashboards, allowing administrators to view and share customised reports.

For manual traceability, a log sheet is available to download.
