Speedy Breedy

Manufacturer: Bactest Limited

Rapid detection of microbial growth on pressure differences

Speedy Breedy is a portable, sensitive, precision respirometer which detects and monitors microbial activity. Detection of microbial activity is determined as a consequence of pressure transients relating to gaseous exchanges within a closed culture vessel of 50 ml working volume, as a result of microbial respiration. The detection limit of the technology is just one CFU per tested sample. The system applies an advanced mixing technology and controls temperature, providing optimal culture conditions for rapid growth of microbes. Gaseous changes in the culture medium are efficiently converted into pressure variances, allowing detection of metabolic processes within a short time frame (Detection times ?10 hrs).


  • Flexible use for rapid on-site analysis
  • 50 mL sample volume in “ready to use” or own culture media
  • Simple operation without a PC; Start-up with only 4 button presses
  • Pasteurisation within the device for safe sample disposal
  • Numerous fields of application in process and product control , hygiene monitoring and stability analysis
  • Suitable for solid and liquid samples including food products, oils, beverages, cosmetics, etc.
  • For aerobes , anaerobes , facultative anaerobic and microaerophilic bacteria and yeasts
