Brownlee Precision is a leading manufacturer of laboratory amplifiers for electrophysiological recording.  Neurobiology researchers in academia and industry find our products high in performance and easy to use. 
Our four-channel analog amplifiers feature differential inputs, high gain, low noise, advanced filtering, and convenient front panel controls.  The Model 410 is a low-cost general purpose amplifier ideal for conditioning signals from a patch-clamp amplifier or headstage.  Our high-performance Model 440 adds many advanced features including 8-pole Bessel lowpass filtering, highpass filtering, line notch filtering, and an ultra high impedance input stage.   Both products feature bright digital displays, simple front panel knobs for adjusting settings, and a rugged rack-mountable cabinet.
