Anti-Microbial Technology

Anti-microbial test results on the BPMpro sensor

The housing of the BPMpro sensor contains Biomaster®, an effective, silver-based anti-microbial technology. Biomaster® is a broad spectrum anti-microbial additive independently tested and proven to reduce bacterial growth by 99.99% within 2 hours, providing lifelong protection against the threat of cross-contamination.

Biomaster® test results on the BPMpro Mark 2 Sensor array (Certificate #: 1034508.37/11877)

  • Samples of the BPMpro Mark 2 Sensor were submitted containing Biomaster® 542
  • Testing was carried out independently at Industrial Microbiological Services Ltd.
  • To determine anti-microbial efficacy all samples were tested to ISO 22196:2011 along with a lab control sample
  • Submitted samples were challenged against cultures of S. aureus (MRSA) & E. coli
  • Samples were inoculated using a known amount of the above cultures and incubated for 24 hours at 35°C according to ISO 22196:2011
  • TVC (Total Viable Count) of bacteria were then recorded and the percentage of reduction calculated
  • The BPMpro Mark 2 Sensor with Biomaster tested by Industrial Microbiological Services Limited to ISO 22196:2011 was shown to reduce MRSA by >99.94% and E. coli by >99.90%.

  • Acinetobacter baumannii: Pathogenic bacteria, resistant to most antibiotics. The illness can cause severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body.
  • Aspergillus niger: Black mould fungus. Irritant spores with mycotoxins. Pathogen, causing respiratory diseases and cutaneous and subcutaneous infections. Commonly found in bathrooms.
  • Candida albicans: Saprophytic yeast found in the nasopharynx and faeces. Causes thrush and skin infections.
  • Campylobacter: Gram negative, pathogenic bacteria. Causes Campylobacteriosis, resulting in cramps, fever and diarrhoea.
  • Enterococcus faecalis: Inhabits gastrointestinal tract of humans and other animals, can cause life-threatening infections in humans, especially in the nosocomial (hospital) environment.

  • Enterobacter aerogenes: A nosocomial (hospital-acquired) and pathogenic bacterium that causes opportunistic infections including most types of infections. It is generally found in the human gastrointestinal tract and does not generally cause disease in healthy individuals.
  • Extended spectrum beta lactamases (ESBL): These are enzymes which have built up a form of resistance to commonly used antibiotics, such as penicillin. ESBL enzymes are produced by two different forms of bacteria: E. coli (Escherichia coli) plus Klebsiella pneumoniae. The term ESBLs is used to refer to the types of bacteria that create ESBL enzyme.
  • Escherichia coli: Facultative anaerobic gram negative bacillus serotype, found in animal intestines and faeces. Strain 0157 H7 is particularly pathogenic, causing gastroenteritis, sometimes fatal.
  • Klebsiella pneumoniae: Aerobic gram negative bacillus, part of the normal intestinal flora of animals and humans. Pathogenic, causing hospital and community acquired infections.
  • Legionella: Gram negative, aerobic, pathogenic bacterium. Infection can lead to Legionellosis (Legionnaires Disease or Legion Fever) which can also lead to pneumonia.
