Extracellular Applications Utilizing Glass Microelectrodes

Extracellular Applications Utilizing Glass Microelectrodes


For rare instances when using extracellular amplifiers with glass, you could use the setup shown below. In this setup, a DAM80 is shown, but you could easily substitute an ISO-80. Likewise, this setup shows the 2505 handle (1/4" - 6.3mm), but if you have a smaller micromanipulator, you may need the 5444 handle (3/16" - 4.8mm). In this illustration, MEH7W-10 is used, but any glass-size MEH7W could be used. (MEH7W-10 is 1.0mm glass, MEH7W-12 is 1.2mm glass, MEH7W-15 is 1.5mm glass and MEH7W-20 is 2.0mm glass.) EP2 is used for grounding in the illustration.

For single-ended applications, however, a 2033 wire adapter on the black connector socket can be connected to the 3294 cable. The tip used depends on your specific needs. In the illustration, TIP1TW1 was suggested. NOTE that the glass is not shown in the illustration below.

ISO-80P

ISO-80P

Replacement ISO-80 Probe

  • ISO-80P is a high impedance probe that can be plugged into the PROBE INPUT socket of the ISO-80. Insert the electrodes that will connect with the preparation/subject under test into the two sockets—one red, one black—on the probe. The probe headstage is epoxy encapsulated within a miniature gold plated metal case. The use of a probe, close to a recording site, minimizes the shunt capacity normally associated with long wire leads from the electrode to the amplifier.

    CAUTION: The probe headstage is sensitive to static discharge and can be damaged by a high voltage shock.
