or manual current generation for histological
marking, iontophoresis, or cell stimulation.
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.
