Variable Interrupter
Product Code : JA-VI-2404
The Variable Interrupter (SKU JA-VI-2404) makes and breaks an electrical circuit repeatedly at a rate the user can change, and is used with an induction coil or stimulating circuit to deliver a series of stimuli to a nerve-muscle or isolated tissue preparation. Changing the rate lets students see how stimulus frequency alters the muscle response, from separate twitches to fused tetanus. JaincoLab manufactures it for physiology and pharmacology teaching laboratories.
