Microbial Activity Measurement System Antares/Spica/Leonis

Capable of monitoring microbial growth activity in real time
This system measures “heat” generated from microbial cells in real time and evaluates the microbial growth activity. Even if a sample is non-uniform including solid or liquid, the system can measure in a non-destructive manner without changing the sample’s original shape.

Applications

  • Monitor how food goes rotten and how preservative is effective
  • Study on food fermentation/brewing
  • Research for preservation of pharmaceutical, cosmetics and detergent
  • Development of a wide variety of antibacterial
  • Preservative study of cosmetics
  • Refined evaluation of effect of medication

Features

  • Capable of measuring samples with every kind of shapes in a nondestructive manner
  • Capable of simultaneous measurement of up to 19 samples
  • Real-time monitoring
  • Capable of growth rate constant
  • Rapid measurement of 100% inhibition concentration MIC
