Tristel Duo NCU


The joint ACIPC and ASUM Guidelines for Disinfection of Ultrasound Transducers highlight that use of skin surface transducers in these areas may require a higher level of disinfection. With cleaning not equating to appropriate disinfection; low-level disinfection covering only a limited range of microorganisms and high-level disinfection being impractical or time-consuming, intermediate-level disinfection provides the answer.

Microbiological Efficacy

Tristel Duo NCU is effective in 30 seconds against microorganisms of concern, including:

  • Human Papillomavirus (HPV)
  • Herpes Simplex Virus Type 1
  • Candida albicans
  • Staphylococcus aureus


Tristel Duo NCU is a chlorine dioxide-based foam designed specifically for the intermediate-level disinfection of non-critical ultrasound probes and equipment such as skin surface transducers, cords, plugs, control panels and monitors. Tristel Duo NCU delivers the required level of disinfection, and is easy to implement in a wide variety of areas where POCUS is performed due to its size and simplicity. These include:

  • Emergency Services
  • Radiology
  • Intensive Care
  • Theatres
  • Renal Ultrasound
  • Birthing Suites & Maternity
  • Physiotherapy
  • General hospital portable Ultrasound

… and anywhere where Ultrasound is used for invasive procedures such as line insertion, musculoskeletal procedures (MSK), needle guided biopsies, anaesthetic blocks and areas proximal to mucosa or areas that come into contact with probe covers.

Product Options & Accessories

Tristel Duo NCU is available in boxes of 2 x 250ml and also boxes of 6 x 250ml.

Each Duo bottle comprises two seperate compartments, containing 125ml Tristel Base Solution (citric acid) and 125ml Tristel Activator Solution (sodium chlorite). When mixed upon pressing the foam pump, Tristel’s proprietary chlorine dioxide chemistry is generated.

Duo Wipes are designed to be less absorbent than standard dry wipes, resulting in enhanced cleaning and
disinfection performance. They are made of 100% non-woven, low-linting polypropylene (18gsm) and pre-cut to prevent shedding when dispensed from the tub.

Duo Wipes do not impede the chemical efficacy of Tristel Duo NCU, they ensure that foam is spread evenly, efficiently and economically and they do not
scratch device surfaces.

Duo Wipes are available in boxes of 6 x 200 Wipes/tub.
