DAM Series Bioamplifiers With Ele ctrosta tic Disc harge P rotectio A family of very low noise battery-operated amplifiers • Gated or manual current generation for histological marking, iontophoresis, or cell stimulation. n! • A very low noise remote active headstage (DAM80 only) is useful for very high impedance amplification utilizing glass or metal electrodes. DAM series amplifiers can be used as standalone units on any tabletop, or use optional clampmounting 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. AMPLIFIERS, ELECTROMETERS Dam50—Basic Amplifier (optional #5447 electrode adapter not included) Optional probe #5489 for use with DAM50 also includes microelectrode adapter #5469. 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: Application Examples DAM50 DAM50 #5447 Adapter GND A GND B Electrode Adapter #5371 Cable #5371 Cable #3294 Grounding Clip #5489 Probe #2033 Adapter #3578 Cable A B Light Stimulation #300102 electrode extension, held by micromanipulators Micromanipulator #5469 Metal Microelectrode Adapter Metal Microelectrode (i.e., TM33B01) Petri Dish Metal Microelectrodes Central Ground EP2 Ag/AgCl Half Cell Immobilized specimen Ag/AgCl pellet Central Ground Extracellular recording using metal microelectrode ERG recording of fly eyes 74 ORDER TOLL-FREE: 866-606-1974 (U.S. only) World Precision Instruments • Tel: 941-371-1003 • Fax: 941-377-5428 • E-mail: sales@wpiinc.com • Internet: www.wpiinc.com
