The VersaSTAT LC Low Current Interface is a research-grade accessory for the VersaSTAT series potentiostats/galvanostats, designed to measure ultra-low currents with high resolution.
Description
🟦 VersaSTAT LC Low Current Interface
The LC Low Current Interface is a plug-in, research-grade option compatible with many of the Princeton Applied Research potentiostats and galvanostats, designed for the measurement of ultra-low currents with greater accuracy and higher resolution than the base system. With the addition of an LC option, the minimum current range is reduced to 4 pA (80 fA with the PARSTAT 4000A) and the current resolution to 122 aA (2.5 aA with the PARSTAT 4000A).
The LC option can be purchased at any time as a plug-in accessory. It consists of an interface cable to connect to the potentiostat and galvanostat, a main body including the high input impedance electrometer and additional current ranges, and the cell leads. Once attached to the potentiostat/galvanostat, users can execute the built-in DC Calibration routine. VersaSTAT 3 users will gain access to the improved E and I Filters as well as additional bandwidth stabilization filters.
➡️ Improves lowest current range of PARSTAT 4000A to 80 fA and current resolution to 2.5 aA
➡️ Enhances lowest current range of PMC-1000 and VersaSTATs to 4 pA and current resolution to 122 aA
➡️ Now compatible with VersaSCAN for high-resolution SECM experiments
➡️ Plug-and-play option that can be easily added to any laboratory setup
➡️ Provides access to more filtering than available with a standard VersaSTAT3
The 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.
