SYSTEM DESCRIPTION: FEATURES


Real time monitoring “Cell friendly” (Max. 30mV/30μA)

Immediate result Up to 8 cultures Wireless connectivity Data logging Long battery lifetime (100mA/10mA@±5V)

Compact and light-weight design (160x80x25mm)

CONCLUSIONS

Low cost & reusable “biological” oscillator for Cell Culture growing measurements.

Amplitude and frequency to characterize occupation. AGC for better noise inmunity Frequency and AGC control voltage (Vg) to extract Fill

Factor (ff) parameter. Potential fields of application: medicine and biology
