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
Specifications
- Spica (24s amples)
