Cat S42 with Biomaster the first fully antimicrobial mobile phone

Reading, UK-based Bullitt Group, makers of military-grade smartphones and the global licensee for Cat® phones, has launched the first fully antimicrobial mobile phone - the Cat S42.

The entry-level Android smartphone with antimicrobial protection is designed for military use but is now also available to the public.

Every exterior component of the product including the screen made from Corning Gorilla Glass 5s has been treated with Biomaster antimicrobial technology and tested to ISO 22196.

Biomaster technology inhibits the growth of microbes on the phone surface offering protection for the lifetime of the unit. 

Research shows that mobile phones harbour thousands of germs, with one University of Michigan study finding in excess of 17,000 bacteria on handsets. According to research from Deloitte, on average we interact with our mobile devices around 47 times daily.

Bacteria or other microorganisms can easily transfer from the hard surfaces of your phone to your hands and face.

Biomaster technology combines with the existing Cat phone rugged credentials that ensure the device can be thoroughly and regularly washed with soaps and water, sanitisers and even bleach.

Peter Cunningham, VP Product Portfolio at Bullitt Group says: “Throughout 2020 we have consistently been driving awareness of the importance of mobile hygiene for us all, but this is vital for those among our customers working within a health or social care setting and those visiting multiple sites for their job.

“Using a Cat phone already allows them to have confidence that they can wash and sanitise their Cat phone regularly or between visits. The addition of antimicrobial product protection into the Cat S42 is another first for Cat phones and will make the Cat S42 more hygienic for users – such an important feature in the current climate.”

The Biomaster-treated Cat S42 is the first of a series of devices in the Bullitt Group phones range with antimicrobial technology with others coming later in the year.

The Cat S42 is extremely tough. Tested to Cat phones’ demanding standards, it features MIL SPEC 810H and IP68 and IP69 ratings and surpasses rigorous and repeated drop testing from 1.8m onto steel, including multiple drops onto every side and corner. It is fully waterproof, tested submerged in water at depths up to 1.5m for 35 minutes. 

All Cat smartphones are also put through vibration and tumble tests, salt mist conditions, and are built to operate in high and low extremes of temperature and to survive thermal shocks. 

The Cat S42 smartphone currently has an MSRP of £229 / €249. For more information visit
