VersaSTAT 3F是VersaSTAT 系列的最新機型，儘管與VersaSTAT 3（10µs資料擷取、±650mA電流範圍）及VersaSTAT 4 (4nA較小的電流範圍、加強的濾波選購)有相似的規格，VersaSTAT 3F是專為搭配接地電解池的操作而設計。
VersaSTAT 3F的“F”意指“浮接”，用於說明系統電極導線和背面板連接器與接地的電隔離。在浮接模式中，VersaSTAT 3F的內部接地（及電解池導線與背面板上的外部連接端）是容許對接地的電解池浮接。比如，接地的電解池包括：高壓滅菌鍋、應變規器械、儲罐與管道，以及連接到不浮接的獨立恆電位儀的額外電極。
VersaSTAT 3F的設計，可採“一般”模式（同機型VersaSTAT 3和VersaSTAT 4 ）或“浮接”模式操作 – 可於操作軟體內選擇。
除了模式的選擇外，VersaSTAT 3F也提供某些電解池需要的額外濾波器，以加強信號對雜訊比。所提供的特殊“陷波濾波器”，可依需求應用於與電源（50/60Hz）有關的頻率；“EIS濾波器”，可應用於配備FRA選購的系統。
能以浮接模式搭配接地電解池及電極操作。
提供適用於浮接模式操作的特殊濾波器，可加強信號對雜訊比。
標準提供±650mA/±10V極化範圍。
內部的頻率響應分析儀選購，可提供在頻率範圍10µHz～1MHz上的阻抗分析。
額外的頻寬濾波選購，可在電容性電解池上提供更大的穩定性。

The VersaSTAT 3F is the latest addition to the VersaSTAT family. Although sharing similar specifications to the VersaSTAT 3 (10µs data acquistion, ±650mA current range) and the VersaSTAT 4 (4nA lower current range, enhanced filtering options) the VersaSTAT 3F was designed specifically to operate with earth-grounded cells.
The "F" in the VersaSTAT 3F name is for "floating," a term used to describe the electrical isolation of the systems electrode leads and rear panel connectors from the earth ground. In floating mode, the internal ground of the VersaSTAT 3F (as well as the cell leads and external connections at the rear panel) is allowed to float with respect to earth grounded cells. Examples or earth grounded cells include autoclaves, strain apparatus, storage tanks and pipelines, and additional electrodes connected to a separate potentiostat that is not floating.
The VersaSTAT 3F was designed to operate in either a "normal" mode (same mode as V3 and V4 models) or a "floating" mode, selectable in the operating software. In addition to the mode selections, the VersaSTAT 3F also provides additional filters that could be required with some cells in order to enhance the signal to noise. A special "Notch Filter" for those frequencies associated with line power (50/60Hz), and "EIS Filters" (for those systems equipped with the FRA option) are available as needed.

±650mA/±10V polarization range as standard
An internal frequency response analyzer option that provides impedance analysis over the frequency range 10µHz to 1MHz
Additional bandwidth filtering options for greater stability on capacitive cells
