The A.M.P.I. ISO-Flex Flexible Stimulus Isolator is an optically isolated electrical stimulation unit designed for electrophysiology and neuroscience research applications. The photographed instrument is clearly marked ISO-Flex and A.M.P.I. on the front panel. The ISO-Flex is designed to provide controlled electrical stimulation while electrically isolating the input stimulus source from the output side, helping reduce unwanted noise and stimulus artifacts. Micromécanique

The unit can operate in either constant-current or constant-voltage mode, selected through the front-panel CURRENT/VOLTAGE control. Published specifications indicate an output capability of up to 10 mA in current mode or 90 V in voltage mode, with three selectable output ranges of ×1, ×0.1 and ×0.01. The input signal is specified at 5–10 V. Science Products

The ISO-Flex is battery operated and uses a low-voltage internal battery for operation together with a replaceable high-voltage battery for driving the output pulses. Published documentation specifies compatibility with high-voltage batteries from approximately 9–100 V, with a 90 V battery supplied in the standard configuration. Science Products

The photographed unit shows cosmetic signs of previous laboratory use, including surface marks and discoloration. The condition of the internal circuitry, batteries, output accuracy and isolation performance should be professionally verified before experimental use.

Applications

The A.M.P.I. ISO-Flex is designed for in-vitro and in-vivo electrophysiology research, where controlled electrical stimulation is required while minimizing electrical coupling and noise between the stimulus generator and experimental preparation. Research protocols have documented the use of ISO-Flex as a stimulus isolator together with digital stimulators for neuroscience experiments. PMC

The unit can also be used in experimental neuroscience setups involving stimulation electrodes, nerve stimulation and other research procedures requiring isolated current or voltage pulses. Two ISO-Flex units can be coupled for generating bipolar stimulation pulses. Science Products

Benefits of Refurbished Laboratory Equipment

Refurbished electrophysiology equipment can provide a cost-effective solution for research laboratories requiring specialized stimulation and isolation hardware. A refurbished ISO-Flex can be particularly useful for maintaining legacy neuroscience setups or building experimental stimulation systems around compatible pulse generators.

Using refurbished equipment can also reduce replacement costs while providing access to specialized laboratory instrumentation that may otherwise be difficult to source. For stimulation equipment, however, electrical isolation, output accuracy, battery condition and connector integrity should be professionally checked before use.

Additional Information

The A.M.P.I. ISO-Flex is a research stimulus isolator and should not be represented as a device for direct human clinical stimulation. Published product information specifically states that the ISO-Flex is intended for research use and is not approved for direct patient use. Micromécanique

The photographed unit does not clearly show the high-voltage battery housing or battery condition. Therefore, battery availability, output performance, calibration and internal electrical condition should be verified before purchase or installation.
