The VersaSTAT LC Low Current Interface is a plug-in, research grade option compatible with many of the Princeton Applied Research potentiosntats/galvanostats, designed for the measurement of ultra-low currents with greater accuracy and resolution than the base system. With the addition of a VersaSTAT LC option, the minimum current range is reduced to 4pA (80 fA with the PARSTAT 4000) and the current resolution to 122aA (2.5 aA with the PARSTAT 4000).
The VersaSTAT LC is ideal for ultra-low current applications requiring high resolution. Applications involving ultramicroelectrodes, coatings research, corrosion testing of bio-implants, and sensor development are all areas where greater current sensitivity may be needed.
The VersaSTAT LC option can be purchased at any time as a plug-in option. It consists of an interface cable to connect to the potentiostat/galvanostat, a main body including the high input impedance electrometer and additional current ranges, and the cell leads. Once attached to the potentiostat/galvanostat and calibrated with the built-in DC Calibration routine, additional bandwidth stabilization filters are available to provide maximum stability over a wide range of experimental conditions and applications.
