Features supporting broad spectrum detection

  • Optimised growth conditions to facilitate culture of many species.
  • Mild process conditions ensures culture medium retains activity of heat labile growth enhancers allowing culture of a broad range of microbes including fastidious organisms and those that may be damaged, reducing false negative results.
  • Pressure transients are sensitive to a wide range of gaseous exchanges that reflect metabolic activity of contaminating microbes – the system is not limited to CO2 production as with other biochemically mediated systems.
  • Unlike other pressure detection technologies, Gemini’s detection algorithm can measure both positive and negative pressure transients, allowing early detection of important organisms such as Neisseria and Haemophilus which are invisible to less sophisticated technologies.
  • Each test includes both aerobic and anaerobic culture.
