Identity

Trade Name: Q21 FDA UDI
Generic Name: Multiple physiological signal amplifier FDA UDI
Device Name: The Q21 is a 19 channel EEG amplifier with a low noise floor of 0.25 microvolts peak to peak from 0.1 to 10.0Hz, meaning that you can record brain wave data without worrying about noise contamination. On top of our low-noise design, the Q21 is a non-multiplexed, multi-channel readout amp, minimizing slew for the most accurate whole brain imaging, and giving you the exact readout of your EEG recordings, with no loss of data or smoothing.
