Features
WPI’s DAM series amplifier’s are well known as a standard of the industry for extracellular potential amplification. These battery powered bio-amplifiers are designed with a compact chassis profile that enables the user to locate the unit closer to the preparation and thereby minimize long lead lengths which contribute to noise. Each amplifier is equipped with selectable high and low filters, and a position control to offset galvanic potentials which may develop during recording. A choice of models offer additional features that are useful for certain applications.
Current Generation
Gated or manual current generation for histological marking, iontophoresis, or cell stimulation.
Remote active headstage
DAM80, an AC amplifier only, features a very low noise headstage probe which can be mounted in micromanipulators for up-close cortical recording, for extracellular recording from high impedance glass or metal microelectrodes. Also provides a gated current for tissue marking. Microelectrode holder MEH3SB is recommended.
Portability
DAM series amplifiers can be used as standalone units on any tabletop, or use optional clamp-mounting hardware to locate them conveniently within the work area. Alternatively, a pair of amplifiers can be mounted into a standard equipment rack with a rack mount kit (#3484 ). A variety of hook up accessories are available to configure your application

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.
