Universal Kymograph with or without Stimulator

Universal Kymograph with or without Stimulator

The Universal Kymograph has a spindle 320 x 19 mm OD (12-1/2 x 3/4 in OD) for mounting a cylinder (not included). The speed range, dependent on circumference of cylinder chosen, is infinitely variable by use of two controls. Models 50-7376 and 50-7368 have a built-in square wave stimulator with a maximum output of 25 volts with less than 25Ω impedance.

  • Two fully adjustable support arms each with a 9.5 mm OD upright rod for mounting accessories
  • Adjustable, double contact arms are fitted to the spindle base for external trigger applications (e.g. stimulators)

The Universal Kymograph has a spindle 320 x 19 mm OD (12-1/2 x 3/4 in OD) for mounting a cylinder (not included). The speed range, dependent on circumference of cylinder chosen, is infinitely variable by use of two controls. A manually operated stop is provided to allow the spindle to revolve either continuously or for a single revolution.

Models 50-7346 and 50-7368
The built-in square wave stimulator has a maximum output of 25 volts with less than 25Ω impedance. The frequency range is continuously variable from 0 to 100 Hz. There are six preset pulse widths. The output has three selections: continuous, single pulse by push button, and external trigger via the contact arms on the Kymograph spindle. All the controls are located on the front panel.

Models 50-7343 and 50-7350
These models are supplied without cylinder of stimulator.

Cylinder 50-5560

The Kymograph Cylinder is for use with the 19 mm (3/4 in) diameter spindles of the Harvard Apparatus Universal Kymographs. Each Cylinder has 2 mounting plates for fitting it concentrically onto the Kymograph spindle. A lockable split ring fixes the Cylinder to the spindle at the desired height. This cylinder is plastic and is for ink writing only
