The company’s latest model – Teal Stop n’Wash – not only solves the problem of providing hand wash units in areas where there is no access to mains water or drainage but can also be used as a useful educational tool.

It has a synchronised display which takes users through its automatic programme and seven rubbing actions as laid down by NHS guidelines. Fully automatic and completely hands-free, there are no levers or taps to re-infect hands. It is also pathogen-safe if a simple hygiene cycle using 500ppm chlorine solution is carried out every 24 hours.
