Maxwell Biosysystems MEA

MaxOne High-Density Microelectrode Array (HD-MEA) System


Maxwell Biosysystems MEA MaxOne

MaxWell Biosystems’ MaxOne is a CMOS-based HD-MEA, an electrical imaging system for neuroscience, drug discovery, and cell assessment applications. MaxOne captures high-quality signals at sub cellular resolution from acute tissue experiments (e.g., brain slices, retina) and long-term culture experiments. Simultaneous recordings can be performed by running up to 4 recording units in one system.

MaxOne HD-MEA system allows for easy and vibration-free insertion of the MEA device. It can operate inside cell-culture incubators. Accessories are available for perfusion-compatibility. Microscopy of samples on the HD-MEA surface can be performed using upright objectives. Overall, MaxOne a powerful HD-MEA applicable to all in-vitro preparations.
