Type of option

Ultra Low Current

An Ultra Low Current (ULC) option is available for each channel of the VMP-300 instruments. This module lowers the base current range from 1 μA to 1 pA, thus the resolution of the low current option is 80 aA on the 1 pA full scale range.

It consists of a cell cable with a high sensitivity electrometer in-line that is located close to the cell.

This option is compatible with ARG option and current booster option.

ULC is only compatible with VMP-300 instruments and doesn’t take any slot in the potentiostat/galvanostat chassis.





  • Extend the current range down to 1 pA.
  • Current range becomes 1 pA – 1A
