Electronics Facility – Electrochemistry Hardware
Specialty Electrochemical Instrumentation can be purchased from the UNC Electronics Facility. These instruments are specifically designed for performing various types of Fast Scan Cyclic Voltammetry in freely moving or anesthetized animals, in tissue slices, or simply in “beaker” experiments.
Three main instruments are offered, but many options and modifications are also available. All of these instruments operate with the HDCV Acquisition and Analysis Programs which can be licensed free of charge . UEI instruments have been provided to laboratories worldwide. Please contact Collin McKinney for price lists and information.
Universal Electrochemistry Instrument – UEI
This is a mainframe-based instrument that is customizable by the customer. It can be configured to provide up to four channels of Fast Scan Cyclic Voltammetry, FSCV, and two channels of simultaneous Electrophysiological measurements, EPhys. It interfaces with Med Associates experiment controllers through an 8-bit Superport and it also interfaces with Plexon neurophysiology instrumentation. A wide variety of headstages are offered for in-vivo and ex-vivo measurements. A minimal system consists of a mainframe, power supply, breakout box, ramp filter plug-in, headstage controller, and a headstage.
This is a simpler instrument that allows the user to perform FSCV experiments without the capability of performing EPhys measurements. It also utilizes the HDCV software, but does not require a breakout box. It does, however, support the Med Associates Superport. It requires a headstage to form a complete measurement system.
This instrument is intended for benchtop FSCV-only experiments. It does not utilize either a breakout box or a headstage. Instead of the fixed-gain headstages used with the UEI systems, this unit provides a built-in headstage with computer adjustable gain settings. This unit is ideal for bench experiments or for teaching students about CV and FSCV.
UEI Ancillary Equipment
Other equipment available that interfaces with the UEI system are:
- Specialized or custom headstages for bench, tissue, or behaving animal use.
- Multi-electrode systems.
- Iontophoresis pumps for injection of small amounts of neuro-active compounds directly into tissue.
- Commutators, also known as “Swivels,” used in experiments with behaving animals.
- Flow cell systems for calibrating electrodes.
- Video character generators for annotating real time videos of behavior during experiments.
- Custom systems for real-time, multi-parameter measurements, for example simultaneous FSCV, EPhys, and patch-clamp.
