The LABORATORY MODEL series 820 of MEDICRAFT STIMULATOR is
designed to fulfill the various parameters generally required by an
experimentor in the laboratories of Pharmacology, Neuro-Pharmacology
Physiology, Experimental Medicine, Bio-sciences, Surgery and such allied
field.
The
MEDICRAFT ELECTRONIC STIMULATOR - LABORATORY MODEL is a rigid unit with
variable controls to select a pulse of desired repetitive rate, width and
amplitude facility to operate from a timer and with synchronizing input and
output.
