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.

The BPMpro sensors with Biomaster® Protection have been independently tested to ISO standard 22196:2011:

  • The submitted samples were challenged against stock cultures of S. aureus (MRSA) and E.coli
  • The samples were inoculated using a known amount of the above cultures and incubated for 24 hours at 37°C according to ISO 22196:2011
  • The Total Viable Count (TVC) of bacteria was then recorded and the percentage reduction calculated
  • The BPMpro sensors were awarded certificate #1021642.225/7681

The table below shows the results recorded by Industrial Microbiological Services Ltd. for the BPMpro sensors:

Key: Bacteria 0hrs – CFU of bacteria at 0 hours of testing, Bacteria 24hrs – CFU of bacteria at 24 hours of testing, CFU – Colony Forming Units

Key: Bacteria 0hrs – CFU of bacteria at 0 hours of testing, Bacteria 24hrs – CFU of bacteria at 24 hours of testing, CFU – Colony Forming Units

  • 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.
