Features

The improved ISO-80 provides low noise AC coupled amplification and offers excellent recording performance for monitoring extracellular nerve action potentials in vitro and in living animals. The ISO-80 is provided with a remote headstage (1 m cable) which incorporates an electrode impedance test function and a constant current stimulator. The constant current stimulator can be used for cell marking, stimulation or electrode cleaning. Typical applications include measuring EMG, EEG, extracellular and action potentials in vitro or in vivo. The ISO-80 system is DC isolated from the subject ground and employs state of the art electro-magnetic shielding for improved noise rejection. The amplifier employs both high pass and low pass filtering with gain from 100 to 10,000. The lowest low-pass setting is 5Hz and the upper passband is 10 kHz.

Start-up kit included

Included with the ISO-80 is a Startup Kit containing the following accessories needed for basic metal electrode electrophysiology research: two CBL102 Cable, BNC-to-3.5mm plug, 6 ft (2m), two 5469 Adapter, mini-banana to 0.031 skt, two 13388 Adapter, mini-banana to 2mm skt, one 3294 Cable, ground clip to wire (3 ft), one 2033 Mini-banana plug (black), one 2034 Mini-banana plug (red), two 2035 Mini-banana plug solderable turrent, one EP1 Ag/AgCl pellet (70 mm wire) 1mm diam x 2.5 mm long, two M3301EH Electrode Holder, 14cm, and one package of four 5470 0.031-inch jack on 12-inch wire.

Mutliple applications are available with a variety of options. Here you can see two setups.

DIFFERENTIAL APPLICATION FOR METAL ELECTRODES

In this setup, metal electrodes are used with a differential amplifier. In this setup, a DAM80 is shown, but you could easily substitute a DAM50 (with 5489), ISO-DAM8A (with 74040) or ISO-80.

EXTRACELLULAR APPLICATIONS UTILIZING GLASS

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 ISODAM8A (with 74040) or 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.
