Faraday Cages and Amplifiers

Amplifiers and sensing cages for seamless integration into your research workflow

FARADAY CAGES

Our customizable Faraday cages and adapters serve as an interface between the amplifiers in your lab and pores fabricated inside NNi’s flow cells. We support all common amplifiers and can easily adapt as needed.

VC100 - HIGH BANDWIDTH AMPLIFIER

The Chimera VC100 is a low-noise, high-bandwidth current measurement system well suited for nanopore sensing in the MHz range.

It consists of a small preamplifier connected by a cable to a custom data acquisition
unit. The system is controlled over USB.
