e4

Fully integrated 4-channel current amplifier for multichannel low-noise current measurements. Suitable for arrayed lipid membranes studies.

Design your setup with our PCB

A PCB is provided to connect the amplifier to your experimental setup (e.g. flow cell,
sensor etc.). In addition, a custom designed interposer can be provided to interface with your setup. This flexibility ensures a highly personalized experience, adapting to diverse experimental requirements, while keeping high quality multichannel signal acquisition with very low noise.
