Ποτενσιοστάτες VersaSTAT
Η σειρά VersaSTAT της Princeton Applied Research (AMETEK) είναι ευέλικτοι ποτενσιοστάτες/γαλβανοστάτες σχεδιασμένοι για ένα ευρύ φάσμα ηλεκτροχημικών εφαρμογών. Προσφέρουν υψηλή ευαισθησία, προαιρετική δυνατότητα EIS και ευέλικτα εύρη ρεύματος, ιδανικά τόσο για ερευνητική όσο και για βιομηχανική χρήση.
VersaSTAT Series
The VersaSTAT Series consists of the VersaSTAT3A, VersaSTAT4A, VersaSTAT3, VersaSTAT4 and VersaSTAT3F.
This family of instruments combines our option-based hardware and software platforms to create the most popular line of potentiostats. The VersaSTAT3A, VersaSTAT4A and VersaSTAT3F all offer floating operation, enabling tests on grounded cells (energy applications include fuel cells, electrolyzers; corrosion tests on storage tanks, pipelines, autoclaves).
Hardware and software upgrades further extend the value of the VersaSTAT Series:
• Low Current Interface option (VersaSTAT-LC) extends current measurement to 4 pA range (122 aA resolution)
• FRA option can be added at any time (without return to service) for EIS measurements from 10 µHz to 1 MHz
VersaSTAT3, VersaSTAT4 and VersaSTAT3F all include 20 Amp booster as standard (except when included as part of the VersaSCAN systems). These units are able to operate with or without the booster enabled (20 A or 2 A) and can include the Low Current Interface and FRA options.
VersaSTATs operate within the VersaStudio software package. This software is the data acquisition program for all Princeton Applied Research potentiostats, including single-channel and multichannel designs. VersaStudio has dedicated techniques for most standard electrochemical experiments. This includes actions common in energy, physical electrochemistry, and corrosion applications.
Highlights
☑️ Floating capability included as standard with VersaSTAT3A, VersaSTAT4A and VersaSTAT3F enables tests on grounded cells including fuel cells, electrolyzers, storage tanks, pipelines, cells in autoclaves.
☑️ VersaSTAT3, VersaSTAT4, VersaSTAT3F all include 20 A power booster as standard, (except when VersaSTAT3F is supplied as part of VersaSCAN system).
☑️ Excellent current measurement resolution for corrosion, coatings, and micro-electrode analysis.
☑️ FRA option can be added at any time (without return to service) for EIS measurements from 10 µHz to 1 MHz.
☑️ VersaStudio software is included with all VersaSTAT systems.
Applications and Software
Users can select from the different groups of techniques that are available:
☑️ Energy providing charge-discharge curves (including CC-CV) for Capacity-vs-Cycle Number or Coulombic Efficiency as well as dedicated techniques such as Constant Power, Constant Resistance, and Potentiostatic / Galvanostatic Intermittent Titration Technique (PITT, GITT).
☑️ Voltammetry providing fundamental electrochemical techniques such as Cyclic Voltammetry, Chrono-techniques. The Advanced Voltammetry techniques also include Pulse Voltammetry methods.
☑️ Corrosion providing multiple corrosion analysis techniques, including the most common ASTM standards such as Linear Polarization Resistance (LPR, ASTM G59), Tafel (ASTM G5), Cyclic Polarization (ASTM G61), etc.
☑️ Impedance may be added to any system to provide Electrochemical Impedance Spectroscopy techniques.
VersaSTAT3A Potentiostat Galvanostat
VersaSTAT3A sets the standard for value and flexibility. Its floating measurement capability enables experiments on ground-connected cells including fuel cells, storage tanks, and autoclaves. When operating with another floating potentiostat, it is also well suited to bi-potentiostat RRDE experiments.
VersaSTAT4A Potentiostat Galvanostat
The VersaSTAT4A leads the VersaSTAT family with its high-speed 500 kS/s measurements. Its floating measurement capability enables experiments on ground-connected cells including fuel cells, storage tanks, and autoclaves. When operating with another floating potentiostat, it is also well suited to bi-potentiostat RRDE experiments.
VersaSTAT3 Potentiostat Galvanostat
VersaSTAT3 has similar product specifications to the VersaSTAT3A except that it does not have floating capability and is only available together with a 20 A power booster. If the booster is not needed, the VersaSTAT3A is recommended.
VersaSTAT4 Potentiostat Galvanostat
VersaSTAT4 has similar product specifications to the VersaSTAT4A except that it does not have floating capability and is only available together with a 20 A power booster. If the booster is not needed, the VersaSTAT4A is recommended.
VersaSTAT3F Potentiostat Galvanostat
The VersaSTAT3F has similar product specifications to the VersaSTAT4A and is only available with a 20 A power booster, or as part of VersaSCAN systems. If the booster is not required, the VersaSTAT4A is recommended.
