Antimicrobial metal and plastic enclosures for medical equipment
Released 15 November 2011
To help reduce the incidence of hospital-acquired infections, Vero Technologies is now able to offer
its plastic and metal enclosures and panels doped with Biomaster®, a silver-based antimicrobial
additive in the material, which provides an effective means of reducing bacteria by up to 99.99% for
the active life of the product. The key benefit is that the silver ion material is added to the raw ABS
before the moulding process in the case of plastic enclosures. As the additive becomes an integral
part of the material, the efficacy of the protection does not diminish over time, giving far superior
protection to external coatings that will inevitably degrade through normal wear and tear, routine
cleaning and accidental damage. For front panels and extruded aluminium enclosures, where the
antimicrobial material is added to the anodising process, trials are currently being conducted;
preliminary results show similar reductions in bacterial growth rates to those found in plastic
enclosures.
Biomaster is produced by Addmaster, with whom Vero has a technology partnership agreement. It
has been tested on over 50 different species of bacteria, including the commonly encountered
MRSA, E.Coli, Listeria, Salmonella and Campylobacter species. Independent testing to ISO
22196:2011, using MRSA and E.Coli, has confirmed the effectiveness of the additive. In essence, the
test procedure consists of inoculating test samples with a nutrient mix containing a known amount of
bacteria. The samples are maintained at 37°C for 24 hours with the amount of viable bacteria
colonies being measured. The European test laboratory is the only one outside Japan to have SIAA,
Society of Industrial technology for Antimicrobial Articles accreditation. The SIAA is a cross industryacademic group for supervising antimicrobial technology.
