The Laser Light Scattering based technology allows to follow the growing bacteria from the inoculum step in specific culture broths and to display the kinetic growth curves showing the bacterial count expressed in CFU/ml.
The scattering signals are analyzed, elaborated and converted into growing curves plotted in real time, the mathematical elaboration gives not only a qualitative evaluation of the micro-organism presence/absence but also a quantitative evaluation of initial bacteria amount expressed in CFU/ml
Analytical specificity
Samples are incubated at 37°C and constantly mixed avoiding sedimentation, flotation and growth anomalies typical of several micro-organisms.
Only alive bacteria are detected while the interference of non-bacterial materials like salts, erythrocytes, leucocytes, epithelial cells or dead bacteria signals are eliminated by the initial blank value reading.
Sensitivity
The system is flexible and can be customized, it is possible to set the cut off according to laboratory needs
Real walk-away system for rapid bacterial culture and plate streaking of liquid samples.
The system is composed of two units: Alfred 60AST and Sidecar.
Sidecar streaking unit stocks 240 Petri dishes and up to 12 different media.
The streaked dishes are incubated on board at 37°C for the requested analysis time.
